Is there a way to get the camera on the Streak to take pictures faster? I thought we had a fast phone here... why do I have to stay completely still for 15 seconds so I don't end up with blurry images?
If you're not exaggerating you have some serious problems. Either it's not focusing or there's something else eating up processor cycles.
My camera is faster than any phone I've had before, not as fast as a proper digital camera but fast enough.
i do experience a lag as well but not as bad as other phones and it is manageable. I've noticed if you increase the brighntess you don't have to hold too still and causes less motion blur in the pics.
Also look up vignette, its a 3rd party camera app which has many filters and effects.
I have the exact same issue. The camera takes forever to take a picture. I use the fine 2048*1536 resolution and it takes a good ten seconds from button press to shot. If anyone has any advise on how to speed it up, let me know.
Coreth5
On 2.1 (build 8105) it takes about 2 seconds on a bright day when pressing the on-screen shutter button. When using the 2-stage hardware camera button, it takes close to a second to auto-focus on the half-press, and about a half second to take the shot after proceeding to a full press.
It's no speed demon. It seems noticibly slower than my iPhone 3GS on iOS4.
If it's taking 10 seconds, there's someting really wrong.
My settings are Fine, 5MP, GPS ON, and everything else on auto/default.
I do agree that the camera on the streak is dreadful.
Especially compared to my Nexus which also has a 5MP Camera (ported over from the Desire) which takes absolutely amazing photos.
The Streak's photos are always way over saturated, over sharpened and the focusing takes a very long time.
Hopefully this will be improved in 2.2 or maybe we can even port over the camera from the Desire or something
Is it software that controls the camera function or hardware? Is it possible to have an app to improve the camera?

I've tried many different camera apps on the market and whilst they do offer some improvement (image stabilization, etc.) It still is limited by the slow shutter speed.
I imagine it's either hardware controlled and can't be changed (which i doubt) or it's controlled from the Kernel or something (which could offer room for improvement).
I don't know enough about android really, so i could be completely wrong
I've found a few apps that actually take faster pictures. Fast camera, which has a terrible resolution, takes pictures almost instantly. Retro camera (also low res) also takes pictures quickly. I think the camera speed must be limited by the hardware, which is unfortunate as I would say the camera is this device's weak point.
Ive also noticed my camera shutter pretty slow. Its slow indoors mostly. Outdoors is decent though.

I don't get why its a hardware issue. I tried the option in the camera setting to snap four photos in a row. It take great pictures and quickly maybe its because it lowers the resolution.

How did you set that resolution?, on my Dell with Android 2.2 I can only get 640x480 ubber ugly pictures...
Make sure your camera is in 5 MP mode and not VGA...it will set to vga if you've switched to the front camera and then back...when mine does that it takes several seconds to take the picture and then they are grainy and blurry.

I don't see any option to set it up. I'm running Android 2.2 from Dell (no custom firmware)...
See attached images.
Hmmm, it wasn't obvious that you had more options after scrolling. Thanks!
I honestly can't figure out which is better for the life of me.
Stock camera is awesome. But if only I am taking photos with shutter button. On screen button makes the camera focus again after initially locking focus with touch, although it remembers where to focus.
This may cause some lost moments due to delay in shutter speed.
Now, Google Camera, on the other hand, takes photos instantaneously. Much faster than stock camera from my observation. Lock focus with touch, then either on-screen or shutter button takes photos instantly. This makes me a very happy photographer.
But this might mean that I am losing out on Sony-powered enhancements they made for the stock camera, so I am doing various of tests to see which camera is superior.
As for now, both camera takes exceptional photos, but I can noticing differences in color, where Stock makes colors colder where Google makes it bit warmer.
Which camera do you guys prefer?

can you post some samples from both apps
For me stock all the way. I had a phone with very Shutter speed without focus before. Problem was half of my pictures came out blurry. I'd rather wait a milisec for the focus and have a sharp picture than hammering that button and hope for the best plus for me it's always really hard to keep the cam steady when pressing the touch button. As I said half my pictures came out blurry and out of focus with my sgs3. With the z3 every picture is perfect so far. Never had so much fun with a smartphone camera. And that because of the ergonomics and not because of megapixlz.
But why not have both apps side by side and use the one better suited for the situation?

Galaxy phones are the same i guess. I have an s5, previously moto x and iphone 5 user. Never had blur in my photos, but with galaxy s5 out of 10 i take 7 will be blurry but camera quality is really good if its not blurry on the s5 especially day light
Speaking of cameras, can you turn off the shutter sound in either of these camera apps?
I could turn it off on my old xperia acro s, but apparently Sony has decided this feature was too powerful for the z3 compact.

What settings are you guys using for the stock sony cam? I cant seem to get photos that are as sharp as I'd like. They look great on the z3c display, then i look at them on my laptop and am disappointed. Tried SA, manual, 8mp, 15mp, and all sorts of other settings.

Haha ok. Sometimes it's hard to figure tone on the internet. :silly:
Last time I tried the Google Camera it didn't like the 2 stage shutter. I think Sony did a decent number on the Camera app, so will be using it for the time being.
I am also using the default camera app. Its awesome!
I think the google camera needs a overhaul. Its good for just point and shoot but it lacks features. Lets hope Android L apis can help with this.
I figure I'll keep the stock camera as well as Google camera installed for different purposes. Stock camera for everything else, and Google camera for panoramas and photo spheres. Have not compared the difference in panorama shots between stock and google camera yet though.
I found google camera to be worse in low light situations. However the app Camera jb+, gave me better results allround compared to the stock camera.
Sorry to dig up that rather old thread...but something is bugging me! I can't seem to find the setting to turn out ff the sound
Can someone help me?

This is quite weird since I have a "sound" option in the same menu as you posted.. What firmware are you on?
Crazy...then I'd think its based on what country's firmware is installed...I'm from Germany and some users report (on older Sony xperia z's) that they can't disable the shutter sound.
What coutry are you from? Is there a way to get the camera app from another software? I heard there are also complications with DRM

Sweden :good:
Maybe with the google camera app you can switch off the sound
The DRM complications might relate to unlock/root where some lowlight functions get lost for good - but if rooting/unlocking isn't a matter of life and death I wouldn't do it until a safe method is found.
I'm from germany (german stock .77 ROM, no branding etc.) and I have this option.
I'm a Google camera fanboy now. The stock app isn't consistent enough and too much time consuming. I like simplicity above the ultimate shot. Also like the photosphere ability. This way I can relive the moment in VR.
... not the features we all want like manual exposure, focus and RAW shooting, not even 4K or 120fps video, but:
We can now record Full HD video at 60fps
Real-time ISO: The viewfinder may seem less smooth but the image is more accurate to what you get: at ISO-50 you immediately see if the image will turn out too dark!
New metering setting: "face"!
Touch Block integrated in the settings menu!
Front facing camera now seems to expose on yo face (also, the timer seems added, and did this mode always come with software image stabilisation..?)
Pause while shooting video (thanks HSNalfar3)
Last but not least: a fancier design, obviously :angel:
EDIT: I believe the camera algorithms themselves were updated too. Remember you used to see oversharpening so clearly? Even at ISO-50 you could see these two dark pixel lines everywhere over your photo - well, I can't see those now, and images seem a bit softer anyway. Me likey!
EDIT 2: The option for 60fps Full HD video isn't working for some reason, as confirmed by Hanafubuki. Might be a remnant of newer Lollipop devices...
Mainly the first two points are is very interesting. I've always found it annoying that I couldn't see in the viewfinder how photos at ISO-50 would turn out. That is, if it's dark, then images would turn pitch black but you would only see when you took the photo. Now it's already visible in the viewfinder, so it's easier to change ISO (although the setting is still buried in the menu and having to scroll down in landscape... (c'mon Sony you could've easily done better here as well) ). Also, the 60fps Full HD video is a very welcome addition in my opinion.
Another feature
In the superior auto application, in camera options appears the option Burst with longpress that allows you to keep several pictures while holding the camera button. I think that this is new on lollipop.

I was wondering about the DRM: if I have unlocked bootloader and lost the TA partition, will the camera miss noise reduction after update to Lollipop? Also, there's a DRM fix for KitKat UB, will it work on Lollipop?
Thanks.
Yeah, I saw on the videos that now we have 60FPS recording. That will allow us to do timeshift videos without the app, instead in the actual movie editor. I am still waiting on my T-Mobile Macedonia Europe firmware... :/
I think our device can shoot 4k and timeshift video,perhap sony will get that on the next update. For this update I think it's less smooth than last firmware but less focus time too. :good:
no 60fps!!!
if you dont believe, make a video, open on windows and there it is 29 fps....

Actually, I may have spoken too soon indeed. I posted right before I went to bed and when I tried the 60fps mode afterwards and slowed it down by half in the phone's video editor, it did indeed seem as choppy as 15fps video...
Either Sony forgot to implement it or, which I think is more likely, it was a remnant of Lollipop for newer Sony phones. Either way, it's a shame it isn't working.

Wasn't this possible before? My Sony Ericsson Satio and Nokia N8 could both do this already.
I'll add it to the list
Same here with the FHD 60FPS . It olny records at 30 FPS . I smell a new update prety soon from Sony to fix the bugs .
Overall the z1 takes better pictures than before and the camera is fast now
Real time ISO is not a excuse for a laggy view finder... Even My Tablet Z with and old SoC and lower ISP running 4.4.4 has also Real time ISO and doesn't lag as the Z1/C.

on cm12 UB it worked fine
I think the pictures quality got very better than before. especially on 20MP it takes very good images with good details. on the kitkat 20MP took blurry images for me. also the images size got bigger. on kitkat with 20MP was around 5MB and now it's around 9MB :good:

Hi there,
As everyone knows, default camera app of sony sucks. I have tried a lot of alternative applications. For me the best results is from Snap Camera with settings 20mpx, camera api2, jpeg quality Best, opengl2, auto scene auto whitebalance, auto flash. These settings allows me to take much sharper images tested on my small facial hair. BUT! Camera is very overheating, after few minutes (5-6 shots) i have started sony camera and it alerted that camera is too hot, so it shuts down.
Snap camera allows HDR in 20mpx also any scene, its not limited as sony-s camera
Also snap camera produced the best images on my old low quality mtk based phone. So i recommend it, its paid but as far i know it have trial version.
I will be happy if someone will tell how is satisfied with this app.
PS.: FV-5 is worse, for my eyes.
in the play store info, there is setting for ISO. but why is there non when i check in setting...?
ive taken some kick ass photos in good light/ low light / bad light with the stock app. IDK what everyone is on about. but to each their own =)

In Auto mode or Manual?
Both.
Basically, when you unlock your boot loader, the great photo quality will be gone. If you have backed up your "TRIMM area" before unlocking it (where the DRM keys are stored), then you'll be able to get it back, by re-locking the BL, but this means you'll lose your ability to use costom ROMs, only modified stock ROMs are possible after that.
The reason for this is that Sony uses some pretty amazing software magic to get great pictures in low light (noise reduction algorithms) which aren't meant to be accessible for others to reverse engineer, so they lock them away with the DRM keys. So with a locked boot loader, the camera makes awesome pictures even in low light, with an unlocked BL, meh... (not so much any more)
Of course, these algorithms are only available to the Sony default camera app for the same reasons...
Have you tried this
It will let you have scene's and HDR in 20mp, also it has more ISO options.
I've used FV-5 from the start and imo it's a lot better for me then the stock app. I can't work with the stock app that has limited control
Sent from my D5803 using XDA Free mobile app
stock camera is the only one...'cause of manual iso... fv-5 has good auto but you can't force iso 100, 200 and so on
Recently I have the Z3 Compact therefore not yet tried everything, but the camera does not seem anywhere near what they sold me in reviews. The original camera seems poor choices, the automatic mode leaves much to be desired, especially in low light because when you have a lighthouse in front can not interpret well and properly handle white balance and contrast.
I was testing the Open Camera app and gives me better results than stock. The only thing I use it now for the stock camera is for timeshift and sometimes for panoramic shots.
I have almost forgot about this post, thanks for cleaning my bookmarks.
Thanks for everyone’s reply, I have figured out that another phones also uses that sensor and they make better pics, so probably problem is with sony's software developers who are doing a weak job. I am very addicted to zooming pictures and when I compare zoomed 5mpx downscale shot of lumia 1020 and 8 or 20mpx shot of Z3C, then shot of lumia is sharp and clear, full of details.... the shot of sony is like blurred and without details. So i think that they algorithm is wrong somewhere or they are compressing raw to too low quality and when jpeg is created then its final quality will be even worse regardless of 97% or 100% jpeg quality. Need to note that nokia's sensor is three times bigger in its physical size that captures the light.
But the video quality is epic i have never seen so good video quality from phone.
Currently i am waiting for availability of 5.1.1 in slovakia
Have you ever checked this folder /system/etc/camera? You can tune noise reduction, sharpness, contrast, hdr, night mode, light mode, nice food, scene recognition and many other algorithms as well. I have no knowledge and experience but if you want you can try and share your experience.

LOL! Why did nobody recognized before??
There was a mod that tuned camera long time ago, but in a different way - https://forum.xda-developers.com/honor-7/development/mod-camera-mod-100-jpeg-compression-t3340978
Anyway, Honor 7 camera is amazing and highly underrated - mostly because of too much noise reduction and too big jpeg compression. Just by changing camera app to a third party one (like Snap Camera for example) that allows you to change jpeg output quality to something about 90-95% makes REALLY BIG difference. Stock camera app simply compresses files too much and in effect reduces quality and amount of details. Files from stock camera are like 5-7mb each, while the ones from third party app are like 14-20mb! One problem though - sometimes, when image photographed scene has actually too much detail and resulting image exceedes 20mb you get nothing. Probably some memory issue.
Thing is, Honor 7 had great potential (and camera was just a part of it), but the interest in this device was killed by Honor itself. People who owned it mostly already sold it as there are big issues in current software that will most likely never be fixed. Therefore i would not expect to get much developement in camera area as the userbase is now reduced. It wasn't big year ago and it's only getting smaller and smaller.
Not much replies here. Anyone oriented on this matter yet?
First of all, I tried third-party camera app (Open Camera) that gives me 100% jpeg quality option, but I haven't tested real life quality out yet. Definitely bigger file size.
Video is the one I'm trying to focus on, tho. Open Camera gives me options for bitrate. Tried 50 and 40 Mbps. With higher dynamics real life framerate didn't go over 14 fps. With locked and somewhat under adjusted exposure, it can handle 30fps on 1080p. But it's no good when trying to shoot "professional" video. Didn't check the real life bitrate either.
As supevixen stated there's some threshold on bitrate and/or jpeg compression buffer. Any idea why?
So what I'm trying to solve is;
- Why there's so low threshold on buffer and can it be optimized? Could it buffer better if I used fast external SD instead of internal?
- How to optimize buffer to match hardware maximum?
- Should I continue using third-party apps or should I try to optimize stock camera .xml files?
- How to reduce denoising? (xml optimization)
- How to lock frame rate and/or shutter speed on video recording? (xml optimization)
I'm not very familiar with jquery or imx230 or much about the Honor 7 SoC either. I'm fast learner and very interested on optimizing the camera.
Ok, here we go. I'd figure that: "/system/etc/camera/multidenoise" -> "multidenoise.xml" is for the "selfie camera" as it states attributes for IMX134 and IMX135. So this doesn't need optimization, if I'm getting this right. "/system/etc/camera/davinci/imx230" has "hdr.xml", "imgproc.xml" and "multiframe.xml" files. "imgproc.xml" I believe has everything to do with the image processing. "multiframe.xml" has everything to do with denoising and luma enhancing, I recon. How to properly reduce denoising? Should I also tinker with luma enhancement or image processing? Also, as I stated I'd like to lock down the shutter speed on video recording, with frame rate set to 25. "/system/etc/camera/bshutter/imx230/" -> "algo.xml" has algorithms for shutter behavior. Any way to optimize those?
Or should I simply throw this peace of crap out of my life? Camera has great potential anyway, would be shame to toss it away.
If there's someone with some knowledge on the matter, I'd be more than grateful. Thanks in advance.
anamorphica, i didn't try modding original camera app by editing various files as i don't wan't to lose warranty, but i've tried many different camera apps and best one i've found is Snap Camera which paid version i'm using right now. Why? Simply because it can save jpeg files with 100% and it makes HUGE difference. Just imagine - files saved by stock camera are about 5-6MB each where files saved by Snap Camera are about 16-20MB each! And difference is really BIG when you zoom just a little bit and as we have 20mpix camera sensor it actually does make sense to "zoom" by just cropping full image to desired part and gues what - it is possible with good quality images. Of course you can save jpeg's with different quality in most third party apps (like Open Camera or Zoom FX for example), but Snap Camera seems to work best for me (it's interface is ok, it does have many useful options) and it also has amazing HDR mode (three images with different exposure are stacked together for final one - there are other apps that work that way but believe me - results from Snap Camera are by far best)
There is however one downside - sometimes, when detail quantity is to big and output image exceeds ~20MB files are not saved. It happens rarely (really) but it has to be somehow connected with amount of memory needed to that amount of data (in RAW data it has to be much more than just compressed 20 megabytes) and that's probably one of the reasons why stock camera app saves such highly compressed images. Take note, that every other "creative" mode in stock camera doesn't output full res images (light painting and night mode - they're about 8 or 10mpix as i remember) and i'm pretty sure that's also connected with memory limitations (probably not whole RAM - just the part available at the moment for camera sensor and GPU)
As for video quality, there's probably not much we can do, as our Kirin SOC is limited. Where Sony smartphones with same IMX230 can record up to 4k and have OIS, we can do only 1080p with just electronic image stabilisation and pretty low bitrate. Slow motion is also pretty bad with framedrops...
Anyway, as for me, Snap Camera is the best and i'm not going to mess with stock one. Just when i need those light painting modes or night mode - it's ok. But in good light i'll stick with Snap.
Thanks for your reply.
I'd like to know if buffer is really low/restricted due to hardware limitation. As I see it, Kirin is overkill for the needed buffer and RAM should be more than enough.
Someone made 100% jpeg quality mod to "media_profiles.xml", but every bitrate etc. values were set to very odd numbers. It's just hard time to believe that this phone couldn't handle more than what it does now.
btw. I read somewhere that Honor 7 GPU would be plenty for OIS as it should be implemented on IMX230 and people was waiting for firmware update to fix much of those restrictions, well we all know that update never came.
Our Kirin is not that good actually. Not only it does have issues with energy management (that's why apps in background are killed on stock roms and why battery times are much less impressive with CM roms - without agressive app killer built in stock firmware) but it is also crippled on GPU part (no Vulkan compatibility) and not really video capable - like i've said, phones based on different SOCs with same camera sensor are more capable (different codecs etc.) Our phone can't even record perfectly fluent slomo video with stock app - just try it, it's never without freezes.
All in all, i don't think it's worth mess with internal configuration files - you won't get too much probably, at least on video part.
