摘要:
An image encoding apparatus configured to perform sub-band encoding, the apparatus includes: a plurality of encoding units configured to encode an image signal separated into a plurality of sections; a plurality of storage units configured to hold data encoded by the encoding units; and a control unit configured to determine capacities of encoded data of the section of the separated image signal on the basis of statistical information capacities of the section of the separated image signal and data capacities after encoding by the encoding units.
摘要:
A transcoding device (100) includes a decoding unit (10) that decodes both motion vectors of macroblocks and images from encoded images in a first encoding format; a first decoded image storing unit (10f) that stores therein the decoded motion vectors of macroblocks and the decoded images generated by the decoding unit (10); a vector searching unit (20a) that searches for motion vectors of macroblocks for encoding in a second encoding format by using the decoded images stored in the first decoded image storing unit (10f) as reference images and by using the decoded motion vectors of macroblocks stored in the first decoded image storing unit (10f); and a motion compensating unit (20c) that reads, from the first decoded image storing unit (10f), areas in the decoded images, which are indicated by the motion vectors of macroblocks for which the vector searching unit (20a) has searched, and performs motion compensation by using the areas in the decoded images and the motion vectors of macroblocks for which the vector searching unit has searched.
摘要:
An image encoding method causing a computer to execute a process, the process includes: calculating, from an encoding throughput for image data to be encoded that is obtained based on a parameter regarding an encoding throughput, and a maximum throughput of an image encoding apparatus, an available throughput that occurs in a process of encoding the image data to be encoded; allocating, in accordance with the calculated available throughput, a function of enhancing precision of encoding to the image data to be encoded; and encoding, by using the allocated function, the image data to be encoded.
