Document Type and Number:
Japanese Patent JP6404794
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an image information acquisition method, an image evaluation method, an image information acquisition device, an image evaluation device and an image processing program, for precisely evaluating picture quality of an image in which repair process is performed on a missing region.SOLUTION: An image information acquisition method includes a feature amount extracting step of extracting a feature amount from a pixel corresponding to a profile of a missing region, in an input image. The feature amount includes at least one of a first feature amount that is obtained based on a color of a pixel on the profile and a color of a pixel that is not included in the missing region positioned in a periphery of the pixel corresponding to the profile, a second feature amount that is obtained based on an edge intensity of the pixel on the profile and an edge intensity of the pixel that is not included in the missing region positioned in the periphery of the pixel corresponding to the profile, and a third feature amount that is obtained based on an edge orientation at the pixel on the profile and an edge orientation at the pixel positioned in the periphery of the pixel corresponding to the profile, not included in the missing region.SELECTED DRAWING: Figure 6
