Image processor, imaging apparatus including the same, and image processing method, with blurring processing of background image
Abstract:
An image processor performs blurring processing on an image acquired via a lens system and including a main subject image and a background image, and includes an image processing section having a reduction rate determiner part which determines a reduction rate of the background image based on at least one of a focal length of the lens system, a distance between the main subject image and the background image, level of the blurring processing, and an image size of the background image; an image reduction part which reduces the background image at the reduction rate determined by the reduction rate determiner part; a spatial filter processing part which performs spatial filter processing on the background image reduced by the image reduction part; and an image enlargement part which enlarges the background image processed by the spatial filter processing part at an enlargement rate as an inverse of the reduction rate.
