I have got another camera with OV7725 and the image colors are more hot and more red compare to the M7 which the colors are more white and cold.
This whiteness seems to blur the images like big aperture reduce depth of field.
This other camera uses the OV529 ftom omnivision too, i dont know the dont use special algorythm for AEC, AGC, Gamma correction or whiteblance....
I red the camera datasheet and i tried to modify register to get hotest the camera colors and better quality.
I changed :
- AEC ROI at address $0D
AEC before and after Gamma at address $67
Do you have an idea except to use manual control ?
