Has anyone got any knowledge or can point me in the right direction to mod the trinitys main camera to see in the dark with IR leds? if possible hooking these up to the trinity. I don't mind running the phone without covers if possible.
In normal case can your camera "see" IR in the dark. I have tried, my camera on my trinity does it. Hold an IR-remote control to your camera, press any key on it and you will see flashing the IR-LED, you can't. I test so my remote controls. If it works, try it with a big IR-lamp or many IR-LED's.
any digital cam can see ir-remote's led flashing

Well I just got my JasJar and when I press the camera the app comes up and then nothing but a black screen. Is there any software update out there? The camera that is on the screen works but not the one on the back.
Jr...
I believe that you able to do an exchange...most probably your camera hardware is faulty.
having the same problem with camera. Screeen is black but video cam still works
.. any suggestions?
dont point it to the ground? ensure you are in a vary bright place! make sure you dont have the cover over it!!! adjust the settings by clicking on the tools on the bottom right and adjust ambience and settings, really get creative and perform your own manual adjustments. switch the flash on?
the camera is **** and dark, so dont expect miracles.
alternatively, send it back. it should work.
Do what Simon suggested but if that doesn't help, change the settings in Camera to Auto incase its on something else. You mentioned that video cam works but camera mode doesn't. What about the other modes like Burst, Sport etc etc?
If nothing helps, try a soft-reset. If that doesn't help, try a hard-reset. If that too doesn't help, then a ROM re-install is in order. Now, if that too doesn't help, then i'm sorry but you will need to send it to the service centre.
I just bought a new Logitech mouse with tons of customizable buttons on it, and it got me thinking...what if you could use your PPC as a mouse for your PC? That would be the ultimate in customizability!! Think of it...not only would you have a bunch of hard buttons to play with, but you could also have a customized screen for whichever app has the focus on your PC!
I am nowhere near advanced enough to do this, nor do I know if it's even possible...just throwing it out there as an idea for whoever wants to take up the challenge. I figure it could work on most devices because the camera and flash LED are on the opposite side from the screen and buttons, and BT could be the wireless link. Heck, for that amount of customizability in a mouse I'd even settle for a wired USB version :wink:.
Well enough fantasizing for today...
you're talking about using the camera as the optical sensor?
you'd need it on a special mouse mat that emits light of some kind, and I doubt the feedback would be quick enough.
and i wouldn't fancy pushing my expensive xda around on the desk like a mouse.
Right, I was thinking of the camera as the optical sensor, and the flash LED as the light source. I have a XV6700/Apache, and when I turn on the camera and the flash and set it down on my desk, the screen isn't completely dark because the camera isn't flush against the surface...there's still enough space for light from the LED to reach the lens. Obviously this would vary from device to device...but even in cases where it's completely dark, you could put the "mouse" on top of a few mm of clear plastic or plexiglas to give the LED enough room to bounce the light over. Actually, this option might be desirable as it would address your concern about pushing your device around and getting scratches on it.
In fact, now that I'm thinking about it, using plastic/plexiglas might be better for battery life too. Instead of having the flash stay on all the time, the "mouse" could use the ambient room light to detect initial movement, which in turn would trigger a "wake event" for the flash, and then obviously the flash could be timed to turn off after so many seconds of being idle.
I know speed would likely be an issue as far as feedback goes. Sure, it wouldn't be as quick as my new Logitech laser mouse, but in video mode the camera (at least on the Apache) can go up to 19 fps...so perhaps it would be doable. Obviously you're not going to use Photoshop or play Quake with the thing . I was just thinking added convenience for everyday usage.
well all optical mice i've used have gon crazy on shiny surfaces
their cams are even made directly for this purpos
so i would think using the pda as a mouse would mean it would go even more crazy on a shiny surface
try search i recall posts about this in the past
Issues
light souce: prolong usage of you flash is bad. The life span of the flash may be different for different devices, but I'm pretty sure HTC doesn't give you a nice LED flash to be used for more than 30 seconds per usage. There are reports of 'dying' flash after using it as flashlight.
camera (major issue): phone camera is a fix lense camera (there are a few new Nokia/Sony model that arent). Such camera is not able to take clear picture of close distance object. Try taking a picture of something at a range of 3 inches , at best possible light condition. You won't get a decent picture. Even high tech digital camera is not able to take any picture of any object that is in range of less than 3 inches (even with Macro e.g. the flower, mode on). You can't do much 'mous-ing' with blur images.
It is a good idea though.
just an idea, but what about just using it as a touch pad??
dahquim
Very expensive mouse :lol:
Just get an optical RF mouse.. so much cheaper..
Come to think of it, better get a bluetooth mouse that you can use with both your PC and PPC!
Hmm, I don't know. I just imagined a Universal used as a mouse. Not a pretty picture.
Any way, as for the touch pad idea, it's fairly easy to implement, but it doesn't have the resolution to handle even blow average PC screen which is 800x600 pixels.

OK, so let's say you have a clear glass desk and you attach a board underneath it at a distance of 3 inches so it can focus... j/k

I don't think dahquim meant "touch pad" to mean "tablet PC" or a remote touch-screen clone of your PC monitor (you can do that with LogMeIn). I think he meant simply losing the "mouse" functionality and keeping the ability to have the device's screen display "soft buttons" that could execute commands and that would change depending on whichever app has the focus on your PC. That would somewhat relieve one of having to remember different keyboard shortcuts for each different PC app you use. Same idea as the Optimus Keyboard but on a smaller scale.
touchpad.. ?
Touchpad idea is nice - it could work just like touchpads on laptop; ie. moving finger on mobile device screen causes mouse cursor to move on PC screen, tapping mobile device screen causes mouse click.... who'll implement this ? ;-)

hanmin was right pointing these issues. i'll add some more, from a developer's point of view:
-so you want to have this as a wireless device: think of the power consumption: on one hand you need the camera to be on, with the led, and also a wireless connection for transmitting the data like BT or WiFi.. The baterry wont last long
-even if we cant get the camera to focus at nearly 1-2mm, we could still detect movement of some kind (so the idea would work..in a way or another :roll: ). but please note: there are tens of types of devices, you cant get to make the trick for all.
-it wouldnt be very precise: did you even tried to create an icon? you need to tap over the right pixel, do you think it will work with this?
-ok so you're a fanatic gamer : poor device and poor you, on one hand you'll ruing the device, on the other you'll go nuts because... : slow reaction times, low accuracy...
I see that you've thought about the idea of creating a touchpad out of the pocketpcs. I worked on such a project once. It was indeed interesting. The only problem was that: (issues again)
-the screen is not so sensitive to finger pressure as a touchpad is
-you'll mostly have to use the stilus
But at least this approach is functional.

Yes was thinking more the "set of buttons on [email protected] that let you do quick and easy thinkgs to whatever program your using.
For example, how about being able to switch virtual desktops or having a list of programs on the ppc screen that you switch between... a la Alt-Tab??
just ideas, but of course would be completely customisable (macro buttons)

Looks like this guy got the concept up and running on his Nokia...
http://www.pyrofersprojects.com/nokiamouse.php
This is just a very vague idea, but wouldn't it be possible to build an external flash controlled via the headphone jack?
There are several cheap flashes on the market, and almost all can be triggered manually. Whenever you take a picture, the phone simluates that shutter sound of a real DSLR camera.
I'm not big with electronics or even soldering, but shouldn't it be possible to build a device that uses that sudden change of voltage on the headphone jack (the "sound signal" is nothing else than a change of voltage) to trigger an external flash?
Sounds good, but there are so many parameters for syncing a flash device which make it very difficult (I think)...
The phone makes the sound by the looks of it after it has taken the picture, the flash needs to be before the photo is takes so for the method you're thinking a custom app would be needed to make a sound before/as the picture is taken.
I'm no real whiz when it comes to electronics but outputting a sound/signal from the audio jack and have it picked up by some device designed to trigger a flash shouldn't be too complex (more than complex enough for myself ) The problem is going to lie in the program itself. To do it you're going to have to have a camera program load and play a sound and almost instantaneously take a picture. There can not be ANY lag or allowance for latency in this or the flash will be out of time with the snapshot. If the phone is in the middle of doing something else while a photo is taken (background apps or something) then this might delay the loading of the audio file and put the flash out of sync with the snapshot.
just my 2 cents
Perhaps the sync doesn't have to be perfect. If you set a large shutter time (if that is possible at al) the flash would only have to be somewhere between start and stop.
An interesting idea, but if you are going to carry around a DSLR type camera flash, then you might as well carry a small compact camera with a built in flash because size wise there wont be much of a difference. Or if you are thinking of a small LED light to simulate the LED flash of a camera phone, then get something like this turn it on, point and take the picture. I have a dual LED key chain light that I have used once or twice as a flash for the camera (all manual of course).
true but a long shutter time means more chance of blurring the image if it's not held steady
The device wouldn't need to be large, just big enough to hold a battery or 2 (most LEDs require 3v the super bright ones a bit more) and the circuitry to receive the signal and turn the LED on. Unless you can work out a way to power it off the USB port or run a wire inside and run from the battery, then the device wouldn't be bulky or anything.
since you'd need a special app anyway you could just do everything via the usb port then

Not really if the Flash is a real 'flash' and not just a led turning on and of.
this sounds interresting for all flashless devices, i´d suggest to build a camera app thet supports this and gives a signal to trigger the flash. also you could just build the device and suggest support for it to other camera app developers.
can't the usb port of the SGS give out +5V? If yes one can simply attach a led+resistor to the usb port, and you've got flash.
Moved thread to general discussion section
Hey guys/gals, while chatting about the constant autofocus on the camera yiancar suggests we try other camera apps.
He installed "fxcamera" and said it has an autofocus toggle. And suggested I try it.
So I download and loaded it, selected the normal camera, it started autofocusing even without tapping the screen or selecting the autofocus toggle.. Making that focus clicking sound.
His does not... I remember there being mentioned somewhere that they were having issues with quality control with the cameras, don't know if this has anything to do with it.
So if you have a chance, could you please download "fxcamera" and test your camera's autofocus and report your findings here? (mention if your unit does or does not auto focus click constantly, which model, and rom version you're on)
Thanks in advance!
Hi clockcycle
My camera does the continuous autofocus only in difficult light situations, for example in a dimmed lecture hall. When I have enough contrast in the picture it just perform the autofocus when I moved the camera/tablet. This happens with the standard camera app and I also tested fxcamera - the same result.
Can you find a light scenario where your constant autofocus stops?
stefan
Hey all!
I normal only get one long autofocus unless light is really low (very similar to strahl actually) and fxcamera makes no difference (with autofocus turned off and on)
Thia is from an Adam rooted and running utopia.
Please excuse the awful spelling on the above. I'm too new on this forum to be trusted with the edit button yet!
hi CC,
Just want to report to all that I m using EdenX 2.4 rom which is based on latest NI rom 040811. And in this latest rom NI has fixed the constant refocusing of camera issue. I have tested it and camera stops refocusing after few seconds of delay.
now some hacker/developer might want to take on this.. to help us..to get a toggel switch in camera app for manual and auto options...
@clockcycle I would second whatever strahl's mentioned. Seems to work the same for me too.
On a separate note, one bloke in a thread at tabletrom opened up adam, disconnected the auto focus motor of the camera and he's put up a video after doing it. The camera is now fixed focus and works well for him.
I report 3rd then as someone whose camera will keep focusing in bright areas such as a classroom or when pointed upwards towards any lights.
I can also report that while pointing into dimmer directions the camera stops auto-focusing.
While I think that opening it up and disconnecting the wire is cool, I don't want to have to do that to mine.
What files/drivers work with the camera, can we not just replace the ones that are in the working updates with our current roms?
MY REMOTE IS NOT WORKING - REMOTE TESTING
In the event that your TV is not responding to your remote, this could be because of either an issue with the remote, or the TV's I/R recipient, the accompanying test will help figure out which.
On the off chance that it is an issue with the remote, this can be settled essentially with another remote, as opposed to fixes to the TV.
To start with, if you don't mind guarantee that you have new batteries in your remote.
1) If you approach an advanced camera that has a screen, or a telephone that has a camera, turn it on and coordinate the remote at the camera's focal point. On an iPhone, if it's not too much trouble utilize the forward looking camera, the back camera won't show the light.
2) While glancing through the camera, take a stab at squeezing any of the buttons that are having issues and search for a blaze of light. The glimmer is not visible to the unaided eye, and must be seen through the camera's display.
In the event that the remote is working, there will be a blaze of light visible on the finish of the remote.
On the off chance that you see a blaze of light and the remote is as yet not working accurately, or on the off chance that you see flashes while you are not squeezing any buttons, check to ensure none of the remote's buttons are trapped.
On the off chance that the remote is seeming to work effectively (lights showing up just when you press buttons) and the TV is still not responding, there might be an issue with your TV's I/R beneficiary.
In the event that no lights are showing up, and you have tried supplanting the batteries, your remote seems, by all accounts, to be broken.
Trade remotes for your TV might be accessible on our site if your guarantee period has lapsed, on the other hand, if it's not too much trouble contact our Support Team to ask about the accessibility of a substitution remote or ex-guarantee fix.
If your sheild Android TV remote is out of warranty period visit to trust worthy team by dialing 1(866)201-2001
