Since I am using a 3 Mbits FIFO to capture the image I am limited to 512 x 378 pixels maximum for raw images. I can play with the size (e.g.: 640 x 307, 600 x 327, etc), however, to keep the 4:3 ratio I will stick with 512 x 378.
I manage to take some pictures with various resolutions. The pictures are captured raw either RGB555 then “converted” to 16 bits/pixel BMP or YUV then the luminance component is used to create a 8 bits/pixel BMP files. Files are converted to PNG for convenience.
160 x 120 RGB
160 x 120 B&W
320 x 240 RGB
320 x 240 B&W
512 x 378 RGB
512 x 378 B&W
I did not bother playing with the white balance or saturation, the colors may be a bit off.
