1. A learning image generation device comprising:
a memory; and
a processor coupled to the memory, the processor configured to:
acquire supervised data including a learning image and a correct region defined in the learning image as a pair;
acquire a limitation range of allowable pixel values for a first designated pixel belonging to the correct region in the learning image;
generate a plurality of variable pixel values for the first designated pixel belonging to the correct region in the learning image according to the limitation range; and
generate a plurality of variation learning images, wherein a pixel value of a second designated pixel in each of the plurality of variation learning images is respectively a different pixel value among the plurality of variation pixel values, and wherein the first designated pixel in the learning image and the second designated pixel in each of the plurality of variation learning images have same pixel coordinates.
