1. An image processing apparatus comprising: at least one processor; and at least one memory storing a program which, when executed by the at least one processor, causes the image processing apparatus to: identify a plurality of contour regions, each respectively including a contour component, in an image; determine a scatter degree of the plurality of contour regions in the image; increase, in a case where the scatter degree of the plurality of contour regions is greater than a first predetermined value, an emphasis degree of the plurality of contour regions in comparison to a case where the scatter degree is equal to or less than the first predetermined value; and output, to a display unit, the image including the plurality of contour regions, in which the emphasis degree of the plurality of contour regions is the increased emphasis degree, wherein the scatter degree is a degree to which the contour regions are spatially scattered in the image.
