Image processing to control synthesizing results of shading correction when generating wider dynamic range image

Abstract

The present disclosure relates to an image processing device, an image processing method, and a program capable of appropriately synthesizing images respectively including pixel signals generated by a plurality of pixels having different sensitivities. The image processing device includes a synthesis rate calculation unit which calculates a synthesis rate by using at least one of results of predetermined filter processing on a plurality of captured images including outputs from the plurality of pixels having different sensitivities, a plurality of shading correction units which performs shading correction processing on each of the plurality of captured images, a moving subject detection unit which detects a moving subject on the basis of the result of multiplying each of the plurality of filter processing results by a gain of the shading correction processing, a synthesis rate control unit which controls the calculated synthesis rate on the basis of the result of the moving subject detection, and a synthesis unit which synthesizes the plurality of shading processing results according to the controlled synthesis rate. The present disclosure is applied to a case of generating a WD image.
