IMAGING DEVICE, CAMERA SYSTEM AND IMAGE PROCESSING METHOD

摘要

An imaging device includes an optical information acquiring section that acquires optical information of a photographing optical system to form an image in the imaging element, an optical function calculating section that calculates an optical function to determine the correction function based on the optical information, a pixel function calculating section that calculates a pixel function to determine the correction function based on the pixel outputs of pixels positioned around focus detecting pixels, and a correction function selecting section (2172d) that selects the correction function to correct the pixel output to be output from the focus detecting pixels corresponding to current frame, based on the optical function, the pixel function and the optical information.

1. An imaging device comprising:
an imaging section that performs imaging by an imaging element in which focus detecting pixels to perform focus detection are disposed at positions of parts of imaging pixels, and outputs image data; an image processor that corrects pixel outputs to be output from the focus detecting pixels in the image data by a correction function; and a control section that allows the imaging section to repeatedly execute an imaging operation, and acquires the image data corresponding to frames, wherein the image processor includes: an optical information acquiring section that acquires optical information of a photographing optical system to form an image in the imaging element; an optical function calculating section that calculates an optical function to determine the correction function based on the optical information; a pixel function calculating section that calculates a pixel function to determine the correction function based on the pixel outputs of the pixels positioned around the focus detecting pixels; and a correction function selecting section that selects the correction function to correct the pixel output to be output from the focus detecting pixel corresponding to each of the frames, based on the optical function, the pixel function and the optical information.
