Abstract
An image coding device including: an edge detecting section configured to perform edge detection using an image signal of a reference image for a coding object block; a transform block setting section configured to set transform blocks by dividing the coding object block such that a boundary between the blocks after division does not include an edge on a basis of a result of the edge detection; and a coding processing section configured to generate coded data by performing processing including an orthogonal transform of each of the transform blocks.
