Patent ID: 8547386

Claim:
An image processing device comprising: a main object detecting unit that detects a main-object image piece from an image represented by image data; and a painterly conversion unit that converts the image into a painterly image based on a ratio of a region representing the main-object image piece to the whole image, wherein the painterly conversion unit: converts the main-object image piece into a painterly image piece by a first touch with a predetermined roughness and converts an image piece in a region other than the region representing the main-object image piece in the whole image into a painterly image piece by a second touch rougher than the first touch when the ratio of the region representing the main-object image piece to the whole image is less than a predetermined threshold; and converts the image into a painterly image by a third touch with a predetermined roughness when the ratio of the region representing the main-object image piece to the whole image is equal to or larger than the predetermined threshold.
