I saw a previous issue about this, but I don't think there's anything wrong with it. Is there any convention that a valid image should have at least two rows and two columns?

amacle commented 3 years ago

Nope! A 1px by 1px image is perfectly valid

Then for demosaic, if there is only one row, we might not have any red/blue to average, what should the value be then? Should it be zero?

amacle commented 3 years ago

yes, the image would not be tall enough to encode/store any red channel values when applying the Bayer filter as-described, so the red values when demosaicing would be zero
