Dear SK-Hardwired,
First of all, thank you for creating the sony_pixel_shift_processor code repository. I have a question to ask you. I have a Sony A7RIV camera that can shoot Pixel Shift images. For one scene, I can get 4 ARW files and one ARQ file. I found that the ARW files are 6376×9568 in size, while the ARQ file is 6376×9568×4. By reviewing your code, I believe you are averaging the two G channels of ARQ as the final demosaicing G channel. I'm not sure if the actual Sony camera ISP adopts this processing method, as it would result in noise reduction for the G channel while leaving the R and B channels unchanged.
Best regards,
