PROBLEM TO BE SOLVED: To reduce degradation of image quality in a screen center area in an image pickup apparatus that assumes distortion aberration by image processing.SOLUTION: Degradation of resolution performance of a screen center is prevented by specifying a residual distortion amount at a time of lens design, prioritizing image processing distortion correction on the periphery, limiting sharpness recovery processing in a meridional direction, and setting an amount of correction on the basis of a design value as a reference. |
