An image processing apparatus includes processing circuitry. The processing circuitry is configured to detect a positional shift amount of each of a plurality of images; select a composite target image from the plurality of images based on the detected positional shift amount; and obtain a composite image based on the positional shift amount and the selected composite target image.

A shake correction control device includes circuitry to control an ON/OFF timing of horizontal synchronizing signals of an image capture element, and an ON/OFF timing of one or more drive signals used for correcting a shake of the image capture element, shift at least one of the ON/OFF timing of the drive signals used for correcting the shake of the image capture element so as to be out of a period of time during which analog/digital (A/D) conversion processing is collectively performed on pixel signals for one or more horizontal lines of the image capture element, and adjust the at least one of the ON/OFF timing of the drive signals used for correcting the shake of the image capture element with respect to the horizontal synchronizing signals based on the number of the one or more horizontal lines of the pixel signals collectively subjected to the A/D conversion processing.

An image processing unit includes a candidate pixel group determiner to specify each pixel of an image to be processed as pixel of interest, extract pixels having divergence in position in a certain range from the pixel of interest, and determine, from the extracted pixels, pixels having divergence in pixel value in a certain range from the pixel of interest as a candidate pixel group, an associator to associate the candidate pixel group with the pixel of interest, and an image processor to perform image processing on the candidate pixel group associated with the pixel of interest. The image processor selects, from the candidate pixel group, pixels having divergence in pixel value in a certain range from the pixel of interest as a pixel group to be processed, and smoothes the pixel value of the pixel of interest in accordance with each pixel value of the candidate pixel group.
