Abstract:
1. A method of detecting a correction region of an image, comprising: using a processor to perform the steps of: inputting point information indicating a point which is designated by a user in the image; setting a plurality of origin pixels corresponding to start points of region expansion in a region including one eye, the region having a predetermined size which includes the point indicated by the point information; executing the region expansion from each of the plurality of origin pixels in the region including one eye; and deciding on an area, which includes a plurality of regions expanded from each of the plurality of origin pixels as an image region to be corrected, wherein said setting step sets at least two pixels as the plurality of origin pixels, the two pixels including a first pixel corresponding to the point indicated by the point information, and a second pixel selected on the basis of its predetermined evaluation amount in the region having the predetermined size, wherein the executing of region expansion occurs by calculating a difference Vj between the evaluation amounts E of the first pixel or the second pixel and four contiguous neighbor pixels, calculating a difference Vk between the evaluation amounts E of a contiguous neighbor pixel and surrounding pixels surrounding the contiguous neighbor pixel, denoting R
