PROBLEM TO BE SOLVED: To improve an SNR without reduction in the aperture ratio of a photoelectric conversion region.SOLUTION: An image correction apparatus 20 comprises: a dark noise corrector 21 which subtracts dark noise correction data Ad(x, y) of each pixel from plural first pixel data D1(x, y) obtained by plural photodetectors P(x, y) forming an image sensor 11 and thereby generates plural second pixel data D2(x, y); and a sensor sensitivity corrector 22 which multiplies plural second pixel data D2(x, y) with sensor sensitivity correction data As(x, y) of each pixel to generate plural third pixel data D3(x, y).SELECTED DRAWING: Figure 4 |
