Hello.
I try to write method to make converion from rgb_565 byte array to argb_8888
array.
I need this becouse I want to make a lot of image processing from taken
photo and I get image data in byte array rgb_565 format (as I believe).
Firstly after creating reference to Camera i do:
>
> parameters.setPictureFormat(PixelFormat.RGB_565);
>
and push it to Camera.
mCamera.setParameters(parameters);
Then I implement:
onPictureTaken(byte[] imageData, Camera c)
method in Camera.PictureCallback
After I use my own method like this:
convert2ArgbArray(imageData, imageData.length);
Result is a little crappy ;( Maybe someone has ever try to do this, have the
same problem or just can help or have another idea for image processing??
Here is my method:
> private synchronized int[] convert2ArgbArray(byte[] imageData, int
> arraySize){
>
> int argbArray[] = new int[CameraView.PICTURE_HEIGHT*CameraView.
> PICTURE_WIDTH];
> int argbCounter = 0;
>
> int r = 0x00,
> g = 0x00,
> b = 0x00;
>
> for (int i = 0 ; i < arraySize; i++){
>
> if (i%2==0){
> r = (imageData[i] >> 3 & 0x0000001F) << 19;
> g = (imageData[i] & 0x00000007) << 3;
>
> } else {
> g = (((imageData[i] >> 5) & 0x7) | g ) << 10 ;
> b = (imageData[i] & 0x1f) << 3;
>
> //insert into new array
> argbArray[argbCounter] = 0xff000000 | r | g| b;
> argbCounter = argbCounter + 1;
>
> }
> }
> return argbArray;
> }
