Abstract

An object of the present invention is to provide an image processing apparatus, an image processing method, and a program capable of interpolating a gain of a pixel value of a phase difference detection pixel using a gain value even in the case of generating a display image requiring a real-time property. An image processing apparatus (60) sequentially obtains each frame image in time series order of a motion picture and calculates a gain value to be used in gain interpolation of a pixel value of a phase difference detection pixel of a current frame image based on a past frame image obtained in the time series order. The image processing apparatus (60) interpolates the pixel value of the phase difference detection pixel of the current frame image using the gain value.

Dependent claims

An image processing apparatus comprising:

a sensor in which a plurality of phase difference detection pixels and a plurality of normal pixels are two-dimensionally arranged;
an interface that sequentially obtains each frame image in time series order of the motion picture from the sensor during imaging of the motion picture, the frame image having pixel values of the plurality of phase difference detection pixels and pixel values of the plurality of normal pixels;
a gain value calculator that calculates a gain value to be used in gain interpolation of the pixel value of the phase difference detection pixel of a current frame image based on a past frame image in the time series order obtained by the interface;
a first gain interpolator that interpolates the pixel value of the phase difference detection pixel of the current frame image using the gain value;
and
a display image generator that generates a display image of the current frame image based on the pixel value of the phase difference detection pixel of the current frame image interpolated by the first gain interpolator and the pixel value of the normal pixel.
