IMAGE PROCESSING DEVICE, IMAGE SHOOTING DEVICE, IMAGE PROCESSING METHOD AND PERMANENT MACHINE-READABLE MEDIUM Russian patent published in 2017 - IPC H04N9/00 

FIELD: physics.

SUBSTANCE: image processing device comprises an acquisition unit configured to acquire an image formed by capturing the image through the optical system; and a processor configured to provide the image processing with an unsharp mask by using a filter formed based on the information of the optical point dispersion function in accordance with the image pickup parameter of the optical system. And the filter used to process the image with the unsharp mask includes a filter, in which the two-dimensional data on the taps are distributed axially. Herewith the inventive image shooting device comprises an image sensor configured to photoelectric converting an optical image of an object formed through the optical system; and an image processor configured to process the image obtained from the image sensor. The image processor provides image processing with an unsharp mask by using a filter formed based on the information of the optical point of the optical system, and the filter used to process the image with the unsharp mask includes a filter, in which the two-dimensional data of the taps are distributed axially.

EFFECT: ensuring sufficient aberration correction of the complex shape and increasing the sharpness of the image.
