color shift problem #8

Closed StephanPan closed 2 years ago

StephanPan commented 3 years ago

i met the color shift problem that when i use customed rgb image to reconstruct the raw image, the result will dominate by one channel. After reversing demosaicing refering to "unprocessing", the color of img is shifted to the aforementioned channel. image

Hi, I am not sure if I understand the 'color shift problem' correctly. But have you 'unprocess' the white balance before you reverse the demosaicing step? My another guess is your raw data may not be the 'RGGB' pattern. You can check your exif file. It would be helpful if you can post the wrong results here.
