1. An imaging apparatus comprising:
an imaging element including imaging pixels and at least one phase-difference detecting pixel arranged among the imaging pixels to detect a focal point; a reading scheme setting unit configured to set a reading scheme for reading pixel data from the imaging pixels and the at least one phase-difference detecting pixel of the imaging element in a mixed manner to provide mixed pixel data; and an image processing unit configured to correct any of the mixed pixel data including pixel data of the at least one phase-difference detecting pixel, the image processing unit including
a gain adjusting unit configured to adjust a gain of any of the mixed pixel data including pixel data of any of the at least one phase-difference detecting pixel, in accordance with the reading scheme set by the reading scheme setting unit, to provide gain adjusted pixel data,a pixel interpolating unit configured to perform weighted arithmetic addition of (1) the gain adjusted pixel data, and (2) the mixed pixel data of pixels surrounding one or more pixels corresponding to the gain adjusted pixel data, andan interpolation ratio determining unit configured to determine a weighting coefficient used in the weighted arithmetic addition performed by the pixel interpolating unit, in accordance with the reading scheme set by the reading scheme setting unit, wherein a mixing ratio of the pixel data of the at least one phase-difference detecting pixel in the mixed pixel data read in accordance with the reading scheme is determined in accordance with an arrangement of any of the at least one the phase-difference detecting pixel included in the mixed pixel data, and wherein the pixel interpolating unit changes the weighting coefficient of the gain adjusted pixel data, depending on the mixing ratio determined. |
