Pixel correction method and image capture device

An image capture device comprising:

• a color image sensor having a plurality of normal pixels and two or more phase difference pixels, the normal pixel isotropically receiving incident light, the phase difference pixel selectively receiving a part of the incident light;
• a pixel combining unit for performing a same type combining process, in which first pixel signals from the normal pixels of the same color or second pixel signals from the phase difference pixels of the same color are combined to generate a first combined signal, and a different type combining process, in which the first pixel signal and at least one of the second pixel signals of the same color are combined to generate a second combined signal, to produce a composite image, the composite image being composed of a first combined pixel that is based on the first combined signal and a second combined pixel that is based on the second combined signal;
• an edge detector for detecting an edge of a subject by detecting a first direction in which a difference between the first pixel signal and the second pixel signal of the same color or a difference between the first combined signal and the second combined signal of the same color is at a maximum, the edge being vertical to the first direction;
• and
• a corrector for correcting the second combined signal of the second combined pixel through an interpolation process using the first combined signal of the first combined pixel in a case where the different type combining process is performed across the edge, the first combined pixel being disposed in a second direction which is along the edge and vertical to the first direction, the first combined pixel having the same color as the second combined pixel to be corrected.
