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.

Abstract: There is provided an image processing device including an inverse transform unit that transforms transform coefficient data of a frequency component of an image including one or more blocks into an image signal by executing an integer inverse discrete wavelet transform, wherein an integer transform function used in the integer inverse discrete wavelet transform has a function graph that is symmetrical about an origin as a reference.
