Patent ID: 7880778

Claim:
An image pickup apparatus, comprising: an image pickup device having a plurality of pixels which have a plurality of different photoelectric conversion characteristics different from each other on each side of an inflection point; and a characteristic variation correction section which corrects an error of the photoelectric conversion characteristic of the pixels, the error being a distance from standard photoelectric conversion characteristic, wherein the characteristic variation correction section includes: a correction data storing section which stores correction data; an error correction section which corrects the imaged data by using the correction data; a characteristics transformation section which transforms imaged data converted by one of the different photoelectric conversion characteristics into imaged data fitted to another of the different photoelectric conversion characteristics; an correction manner decision section which decides, based on an inflection point of the standard photoelectric conversion characteristic and the correction data, whether the imaged data is corrected by using the correction data or not and whether the imaged data is transformed by using the characteristics transformation section or not.
