Adding special effects to a camera app. - Android Software Development

Does anyone know how to add special effects to a camera app? I'm wanting to do things like vignette and playing with the contrast. There are plenty of constants for the camera object, like white balance, various focus styles, scene modes, some color tinting, etc... But there are apps that do things like creating a vignette (darkening around an image edges) and playing with contrast. How are these things done?

Pictures Themes

A gimmick on the camera is to overlay a picture frame/graphic when taking photos.
Does anyone know how the rules for making these picture themes ?
The one example we have, the faux magazine cover, is a 4 frame GIF,
with no set transparency. It seems to remove the black (#000000) instead?
I have tried to replicate my own, without any success.....
I tried:
A single frame with black
A single frame with transparency
A 2 frame with black
A 2 frame with transparency
etc.. etc...
All at 256 colours..
Does anyone know what is the correct process?
As I need to get an idea sorted before tomorrow morning
cheers

[Q] color control...

just picked up the tab about an hour ago, and just started playing with it... so far, so good
the one thing that stuck out at me so far is the color... it's at least 300-500K too warm, and waaaaaay to vibrant...
is there anyway to tone it down a bit ?
I couldn't find a way to adjust/calibrate the color on the device. I wanted my photos to look correct ... so I created an action in Adobe Photoshop that correctly adjusts the photos before I download them to the SGT 10.1.
Below is a copy of a post I made on the post processing forum on fredmiranda.com:
A little work allowed me to create a Photoshop action that will take images from my normal calibrated NEC 2690 work environment and apply a transform that preps them for use on the Galaxy Tab 10.1. In case anyone needs to get images looking good on a tablet, here is what worked for me.
In Photoshop, I created three adjustment layers.
1. Hue/Saturation - Reduced saturation (this was to overcome the highly saturated LCD on the Samsung).
2. Curves - I adjusted the individual RGB channels in the curves adjustment layer to get the right color balance on the tablet.
3. Exposure/Gamma - I reduced the exposure slightly and adjusted the gamma value to offset the gamma on the tablet.
Then resized the image for the small screen and applied appropriate sharpening.
I standardized on using sRGB for output. I left the original images intact ... this action can be used to create a a custom set of images for display on the tablet.
The good news ... I ended up with a beautiful tool for sharing images.

i guess that's the workaround...
not sure i like having to work around the color issue, but i guess it's better then sitting in front of a booker explaining why the model looks like she just took a bath in orange juice
I think turning off Auto adjust screen power in the screen settings helps the reds a little. There is also an app in the market that will let you adjust the RGB but for the life of me I can't remember what it is called. I uninstalled it because it made the launcher laggy but other than that it worked OK.
Found it: color filter service is the app. Its 99 cents.

will definitely try this app...
rgb controls would be ideal, and will allow me to use a colorimeter...
thanks

Samsung Gallery mod?

Question, Is there a mod or a way to remove the ugly over sharpening filter that the gallery adds to photo's. In google's photo album the pics look great, but in the default samsung gallery photos get over sharpened once you select a photo things get real noisy and hard looking. especially the indoor darker pictures suffer from the added noise.

Changing Focus Peaking color in Manual Focus camera apps

I played around camera apps and founded out the color of peaking focus is annoying with green-ish color. Are they anyway to edit the camera configuration xml and changed it into different color?
Not annoying to me at all.
