Abstract
In a conventional angular mode derivation, comparison of a magnitude relationship is required multiple times to convert gradients of pixel values into an angular mode, and this hinders parallel processing. A gradient derivation unit configured to derive a first gradient being a gradient of a pixel value included in a gradient derivation target image, and an angular mode derivation unit configured to derive an angular mode, using the first gradient, a second gradient different from the first gradient, and two prescribed tables are included.
