Abstract

An image delivery device is, for example, implemented which is capable of better preventing delays even when real-timeness is required. The image delivery device includes operation information acquisition means, image information acquisition means, allocation information generation means, compression means, and transmission means. The operation information acquisition means acquires operation information. The image information acquisition means acquires image information generated on the basis of the operation information. The allocation information generation means generates allocation information representing allocation of numbers of bits during compression of the image information on the basis of the operation information. The compression means compresses the image information on the basis of the allocation information. The transmission means transmits the compressed image information.

Claims8

Dependent claims

An image delivery device comprising:

an operation information acquisition section operable to acquire operation information;
an image information acquisition section operable to acquire image information generated on a basis of the operation information;
an allocation information generation section operable to generate allocation information representing allocation of numbers of bits during compression of the image information on the basis of the operation information;
a compression section operable to compress the image information on a basis of the allocation information;
and
a transmission section operable to transmit the compressed image information,
wherein the allocation information generation section includes a base information generation portion adapted to generate, on a basis of act information representing behavior of a target to be operated in accordance with the operation information, base information with which image quality information is associated, the image quality information representing image quality level of each of a plurality of blocks into which the image information is divided, the image quality level being proportional to a number of bits allocated to each of the blocks, and
the allocation information generation section generates the allocation information on a basis of the last allocation information and the base information,
wherein the allocation information generation section includes:
a weighting block adapted to assign a predetermined weight to the last allocation information;
and
an addition block adapted to add the last allocation information with the predetermined weight to the base information.
