Image capturing apparatus, storage medium and controlling method for correcting a second image by correcting a pixel value of the second image corresponding to a detected defective pixel

摘要

To perform high-accurate correction while securing high-speed process, an image capturing apparatus comprises: an image capturing element having plural unit pixels; a first obtainer obtaining a pixel value of a first image generated by a first method, based on an output signal of the image capturing element; a second obtainer obtaining a pixel value of a second image for autofocus generated by a second method different from the first method, based on the output signal of the image capturing element; a first detector detecting a defective pixel based on the pixel value of the first image; a second detector detecting a defective pixel based on information of the defective pixel detected by the first detector and the pixel value of the second image; and a corrector correcting the second image, by correcting the pixel value of the second image corresponding to the defective pixel detected by the second detector.
