Image processing device and method

摘要

The present invention pertains to an image processing device and method that enable the performance required for decoding to be more accurately understood. The image processing device: generates a file that has an MP4 file format and stores information specifying a plurality of NAL units corresponding to independently-decodable partial images within a whole image in a moov, and stores encoded partial images in an mdat; and transmits the generated file. The present invention may be applied, for example, to an information processing device such as an image encoding device or an image decoding device.
