1. An image processing device comprising:

  • an image sensor having phase difference detection pixels for focus detection arranged at positions of some imaging pixels;

    a first mixing section, arranged within a first region of the image sensor, for mixing pixel values of a plurality of same color pixels including pixels that have been affected by crosstalk from the phase difference detection pixels;

    a second mixing section, arranged within a second region of the image sensor, for mixing pixel values of a plurality of same color pixels that have not been affected by crosstalk from the phase difference detection pixels;

    a crosstalk effect level estimating section for estimating crosstalk effect level of mixed pixel values within the first region and mixed pixel values within the second region, from the respective mixed pixel values; and

    a correction processing section for correcting pixel values of pixels that have been affected by crosstalk from the phase difference detection pixels within the first region in accordance with the crosstalk effect level that has been estimated by the crosstalk effect level estimating section.
