Determination of main object on image and improvement of image quality according to main object
First Claim
1. An image processing device that determines the main object which characterizes an image, the image processing device comprising:
- image data acquiring module that acquires image data that is data of the target image and that is composed of a plurality of pixel data;
color range determining module segmenting that segments the image data into a plurality of pixel data groups according to the plurality of areas into which the image is split, analyzes the image data in terms of pixel data units, and determines the color range exhibited by the pixel data groups;
color range area defining module that defines color range areas by associating pixel data groups that exhibit the same color range and that are adjacent to each other among pixel data groups exhibiting specific color range;
position data acquiring module that acquires position data for the color range areas;
position condition acquiring module that acquires position conditions stipulating the position where an object that corresponds to the specific color range to be present; and
main object determining module that determines the main object corresponding to the color range areas using the color range and the position data of the color range areas as well as the position conditions.

Abstract
A CPU 411 splits selected image data GD into a plurality of areas (pixel data groups), analyzing the image data GD in terms of area units, and determining the color range of the areas of the image data GD. The CPU 411 determines color range areas by associating adjacent areas of the same color range when determining the color range for the areas of the image data GD. The CPU 411 acquires position data for the color range areas that have been determined. The CPU 411 acquires position conditions (main object conditions) from ROM/HDD 413, and narrows the main object candidates to “sky, green, or people.” The CPU 411 finally determines the main object by comparing the position data of the color range color areas and the position conditions corresponding to the narrowed main object.
