Abstract
An image processing device comprising: a recording unit configured to record a previous frame image input before a target frame image that is to be a processing target or an output frame image from the previous frame image; an alignment unit configured to align the target frame image with the previous frame image or with the output frame image from the previous frame image; a correction unit configured to perform a temporal correction process to correct a pixel value of the target frame image by use of a pixel value of the previous frame image or a pixel value of the output frame image from the previous frame image that has been aligned by the alignment unit, with reference to the recording unit; and a generation unit configured to generate an output frame image from the target frame image by use of the target frame image corrected by the correction unit.
