Abstract

The present disclosure relates to an image processing device and method that can suppress increases in decoding processing load. A secondary transform identifier is set so that a secondary transform is performed only when information about a block size indicates a value equal to or less than a predetermined threshold value. The secondary transform is applied to coefficient data derived from image data based on the set secondary transform identifier, the set secondary transform identifier is encoded, and a bitstream is generated. The present disclosure can be applied to, for example, image processing devices, image encoding devices, image decoding devices, information processing devices, electronic devices, image processing methods, information processing methods, and the like.
