Abstract:
1. An image processing apparatus, comprising: a storage unit that records position information for a defective pixel; a setting unit that sets the defective pixel as an interpolation subject pixel, based on the recorded position information; a selection unit that selects an optimum calculation equation for an interpolated value from among a plurality of calculation equations for an interpolated value to interpolate a pixel value of the interpolation subject pixel; and an interpolation unit that interpolates the pixel value of the interpolation subject pixel by using the optimum calculation equation for an interpolated value selected by the selection unit, wherein the selection unit decides whether each of the plurality of calculation equations for an interpolated value can be applied to the interpolation subject pixel, based on the position information recorded in the storage unit; and the optimum calculation equation for an interpolated value is one of the plurality of calculation equations for an interpolated value that can be applied to the interpolation subject pixel, and uses a largest number of reference pixels for an interpolated value among the plurality of calculation equations that are decided to be possible to be applied to the interpolation subject pixel.
