Image processing apparatus, image capturing apparatus, and image processing method
There is provided an image processing apparatus. A first correction unit sets each of a plurality of pixels included in an image as a target pixel in sequence, determines whether or not the target pixel is a defective pixel, and corrects the defective target pixel using peripheral pixels. The first correction unit does not use, in the correction of the target pixel, a defective pixel in the peripheral pixels that is known. A second correction corrects each corrected pixel that has been corrected by the first correction unit using a defective pixel which was unknown at the time of the correction, using the peripheral pixels used by the first correction unit. The second correction unit uses, for the defective pixel in the peripheral pixels used by the first correction unit, a corrected pixel by the first correction unit.
