Claim Text:
1. An image processing device that processes a captured image signal output from an imaging element including a plurality of capturing pixels and a plurality of phase difference detecting pixels, the image processing device comprising: a gain correction processing unit that performs gain correction processing of correcting an output signal of the phase difference detecting pixel included in the captured image signal by multiplying the output signal by a gain value; an interpolation correction processing unit that performs interpolation correction processing of correcting the output signal of the phase difference detecting pixel included in the captured image signal by replacing the output signal with a signal generated based on output signals of capturing pixels adjacent to the phase difference detecting pixel and detecting the same color as a color of the phase difference detecting pixel; and an image processing unit that corrects each output signal of the plurality of phase difference detecting pixels included in the captured image signal using one of the gain correction processing unit and the interpolation correction processing unit, and record the captured image signal after the correction in a recording medium, wherein within a range including a correction target phase difference detecting pixel and a plurality of capturing pixels adjacent to the correction target phase difference detecting pixel and detecting the same color as a color of the correction target phase difference detecting pixel, when a minimum value is Smin, a maximum value is Smax, a value obtained by subtracting a first value from the minimum value Smin is TH the first and second values are based on a value of the output signal of the correction target phase difference detecting pixel and the gain value.
