Classification: CPC H  G | IPC G  H

Claim 4:
5. The parallax detecting apparatus according to claim 2, wherein the interpolation computation is linear interpolation computation based on two pixel values that are continuous in the second direction,
wherein the at least one processor and/or at least one circuit further functions as a control unit configured to, with respect to at least one of the first viewpoint image and the second viewpoint image, perform control to calculate, with respect to each of a plurality of combinations of two pixel values that are continuous in the second direction, a pixel difference value representing a difference between the two pixel values and record the pixel difference value into a recording unit, and
wherein in the first correction processing, when linear interpolation computation based on two pixel values corresponding to the pixel difference value recorded in the recording unit is to be performed, the calculation unit performs the linear interpolation computation using the pixel difference value.
