Abstract
An image processing device includes a weighted image generation section that generates a weighted image in which at least one of an object-of-interest area of an input image and an edge of a background area other than the object-of-interest area is weighted, a composition grid generation section that generates a composition grid that includes grid lines that are weighted, and a composition evaluation section that performs composition evaluation calculations on the input image based on the weighted image and the composition grid.
