Electronic device and image processing method therefor

A method of processing an image of an electronic device, comprising:

• obtaining a focus map based on importance information per region included in an input image;
• obtaining reliability information per region of the focus map based on at least one of brightness information or contrast information of the input image and information included in the focus map;
• identifying sensitivity information of the focus map according to each of at least one type of image quality processing;
• image-quality processing the input image according to the at least one type of image quality processing based on the focus map, the reliability information per region of the focus map, and the sensitivity information;
• and
• displaying the image-quality processed input image.

A non-transitory computer readable medium storing computer instructions that when executed by a processor of an electronic device, cause the electronic device to:

• obtain a focus map based on importance information per region included in an input image;
• obtain reliability information per region of the focus map based on at least one of brightness information or contrast information of the input image and information included in the focus map;
• identify sensitivity information of the focus map according to each of at least one type of image quality processing;
• image-quality process the input image according to the at least one type of image quality processing based on the focus map, the reliability information per region of the focus map, and the sensitivity information;
• and
• display the image-quality processed input image.
