[THINKTANK] Inverted Colors for WebBrowsing

I'm sure you all know our Vibrant's SUPERAMOLED uses much less/no power when dysplaying black and a TON of power when having to dysplay white pixels.
You also all know that most websites are white with black text. My idea is to invert this in browsers such as DolphinHD, the default Android Browser, and whatever other browsers there are.
How would it work? Ideally as a browser plug in (DolphinHD already supports addons) that inverts background color on websites if it detects white and inverts text color to white. It would NOT touch any other color nor the images, video, animations on websites. Just the static background would be black if it's white by default and the text would be white.
That way, a lot of power will be conserved, even on full screen brightness.
Since I do not have the time or expertise to do this, I am just offering the idea for a dev to look into if interested.

Good idea but what about black within photos and such? that'd be insane.

Umm...Inverting colors in photos would just ruin the pictures I think.
I was talking about making the addon look for the html/php/etc tags that specify color for the background and text of a page upon load and alter them before passing it to the browser to load.

Just change the white background to black, and white text to black. No need to invert colors.
Some one must be able to do this... come on!

Looking desperately for the same funcionality!

I think that is a great Idea, I was thinking about that. In the app youverison
It's a bible app. They have a low light setting, turns background black and font white.. I was thinking how great that would be for web browsing.. it seems like an impossible task.

Somebody posted a thread about this a while back. I would love to see oit done, easier on the eyes as well as battery. Steel had this option for one version a while back, or it might have been Dolphin, so it can be done. Adilko and most of the Ereaders have this functionality.

I am using Galaxy S I9000 and I would love such an app. One of my favt website popurls.com is one such site, uses black background and blue text. Also Blackle is a website which is Google Search with black background. Gr8 idea. Wish some developers are reading it.
There should b a quick button for inverting the colors. So that it can b turned off when not required.

I got in touch with the DolphinHD team, and feedback looks promising. Probably I will write the add-on myself so stay tuned!

Thread moved to General.

Have you tried using cyanogen's screen rendering app? You can choose to render the screen in different colors my G1 has it. I can render the screen in red. I haven't seen this porter to the vibrant though.

I created a bookmarklet to invert colors for people using the stock browser, and perhaps more... http://forum.xda-developers.com/showthread.php?p=17149892#post17149892

Small Request to whoever has the Note

Hey! Can someone with a note set a pre black background a the lock screen background and report whether it looks normal? Someone had reported a problem with the gallery background with a black image, but I couldn't find a mention of lock screen there. Just google image search "black" and download and set it as lock screen. Seems to be giving me pinkish hues... same image works fine as a desktop background...

Most lockscreen wallpapers look horrible on my Note, not sure if my 240dpi is causing this. I use another lockscreen app set to transparent, so I don't care.

The Note's screen is 24 bit, so a picture with 16 or 8 bit depth might not be rendered properly.
Best to find a 24 bit image to test, try Google search.

Same here.

Good to know that I'm not alone. Every other background seems fine. Same thing happens with the gallery background when the only image in the folder is a pitch black one, right?

Well all those images render fine in other applications on the phone so its the lockscreen wallpaper 'setter' wich messes it up I think.

Ya, I'm pretty sure too that that is the case...

I have a black lockscreen and it looks great.
I have noticed that when I have 'screen filter' app running, it dims the foreground but causes the background to do the 'grey' thing.
I have most of the auto display stuff turned off (auto brightness, auto adjust screen power)

Looks like the same problem as with the video playback:

That guy mentions that his blacks aren't completely black. Our problem here is that setting a completely black image as the lockscreen leads to a messed pattern with greyish/pinkish stripes...

edit ; same thing occurs on mine. I even created two black background non compressed, 24 bit, one even with 285 dpi.. both show the wierd little gray stripes on lock screen. only notice it in very dim light by the way and even then if i look very close.
this is what i use. both screens look black as night.

So no lock screen issue with your phone?

Use the darker red "sun" wallpaper gallery image - awesome on mine!

I have the same problem...
Has anyone tried restoring?

I set a black image and got the very dark grey bars others have described. However, I reset it to the original wallpaper and noticed that the white-ish parts of my background has bars as well! Just not as noticeable, and its only on the lock screen.
This is my background picture by the way:
http://interfacelift.com/wallpaper/details/2754/yellow_autumn.html

There seems to be some kind of gradient over the image on the lock screen - I'm just using the default for now, but if you set the default as your normal background as well as lock background, there's quite a difference. Could it be this gradient which is causing the issue with pure black backgrounds?

I'm using widget locker and here is my lockscreen with the homescreen wall paper which uses solid black background color

I am having the same issue. I just noticed it yesterday. I really thought it had something to do with the phone going below the minimum brightness it was designed for, but if you look at the notification bar it's still a clean black.
My guess is the phone is compressing the lockscreen wallpaper to save memory.

Can people try WL (If you've purchased it) and see if it does the job?

bug or something i9505 noticed on f8 and before fw

So to make it short. When you install any app with black icon like offitial 9gag app from market try to scroll left and right in app drawer and yo will see black trail behind icon. It also happens in some apps with blaxk background and in galery with zoom in and out. I wonder is it amoled issue or just software. Just try it for your self. And if sombody is on aosp try it too so we know if you have it too.

It's called smearing and it caused by the fact that the pixels are simply turned off when the display need to show black color.
The screen isn't quick enough to "wake" the black pixels so it looks like smearing on the display.

Google ROM doesn't have it, because Google replaced the black with grey, so dark that it almost looks like black. If you set your brightness to full though in a dark room you'll see it's grey. This way your pixels will never be turned off
Me Gusta!

Does it have to do with refresh rate?

[Q] Screen Mode: Standard VS Professional Photo?

I've been trying out Professional Photo mode for awhile now but it just seems yellow-ish.
Standard seems to be okay.
Does anyone else have similar issues?
I was told that Professional Photo mode is more color-accurate

That mode has a larger colour space meant for certain professional photo apps. For movies, and everyday normal life use Movie mode. If you like exaggerated colours go for one of the other options.

Adapt Display Yes.
Auto-brightness No.
I use a Black Background on my Homescreen with White Text (DashClock) and it looks yellowish in either Pro Photo Mode or Movie Mode

I have tried professional photo as well, but somehow went back to standard mode. But for reading books, professional mode is nice as the screen looks warmer.

Weird, I use Ocean HD (beautiful live wallpaper) mostly since I got mine on a charger 90% of the time and discharge it fully every 2-4 weeks. Maybe I forgot to mention a setting or it is a defect of some kind (software or hardware).
Worst case you could reset your phone to default and immediately set it to Movie mode to see if your clean phone already has these problems. Hope you get this resolved soon, and by simple means.

maybe it is something wrong with my eyes. Standard is definitely more blue whereas Pro Photo and Movie are more warm in color.
there's a switch when I reboot my phone from Blue hue to warm.

Yes, after a reboot it starts at a default screen mode setting and after a couple of seconds it checks your settings and then changes it. I noticed this an hour or so ago on my Note 3.

The default is Adapt Display, which on your homescreen exaggerates colours, so my blue underwater Ocean HD screen looks even more blue. It switches to 'normal' blue.
I just checked some more settings, but are you by any chance using Power saving mode or any of those other fancy settings? Having owned 7 Samsung Galaxy devices by now I always immediately make a round through all settings and switch off everything that is useless (to me). I hate stuff like auto-brightness, which may be great in a car if you use the phone hands free.

hmm I use power savings mode but only Limit CPU and Disable Haptic Feedback. I unchecked Auto Adjust Screen Tone too (it supposedly saves power)
Do you use Lux to adjust brightness?
hmm. mine is a black background with just DashClock in White Text. it gets a little yellowish.
In Standard. it is like mint white.

I would disable Power savings etc. for now to see if it helps. I remember some option with "Lux" in it, but really I just disabled Auto-brightness and adjust the brightness level in the notification panel.

I gave it a try before but it still looks kinda warm/yellow. it is not like there is a yellow tint/screen but the screen just looks warmer.

I've actually never seen an Amoled with Perfect white color.. always a bit to the warm side..
I tried both Movie and professional mode, don't like them at all more yellowish/greenish on the white
especially when comparing it to an IPS LCD screen... then the NOTE 3 is very warm and a tiny bit greenish on white (standard mode) only really visible when side by side with example LG G2...
But then on the LG G2 skin tones looks a bit pale, and with to blueish/cold
so it comes down to what you prefer
I'm a bit torn between them... but when it comes down to choosing I think i prefer the Note 3 screen...
Remember NOTHING IS PERFECT

Some apps make screen B+W

I just noticed that some apps, when running in the FG, fade the screen to black and white. Whe these apps are put in the BG the screen fades back to color. Even more weirdly, if I take a screenshot of the screen while it is faded the B+W the image is in full color.
So far I have noticed AFWall+ and Adaway do this. Any idea what is going on? Did I accidentally turn on some obscure setting?

Probably because you added those apps to reading mode (settings - display - reading mode).
