Patent ID: 11928843
Assignee: CANON KABUSHIKI KAISHA
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A signal processing apparatus comprising:
a local decoding unit configured to generate lossy compressed image data, and generate a locally-decoded image;
a decoding unit configured to generate a decoded image by decoding the lossy compressed image data; and
a restoration processing unit configured to perform image restoration processing on the decoded image,
wherein an encoding unit configured to calculate a maximum bit position where a difference occurs between each pixel of the locally-decoded image and an original image, the original image being an image before encoding, for each of predetermined blocks, and calculate a bit greater than or equal to the maximum bit position as an unrestored bit, and the decoding unit, are capable of communicating over a network, and are capable of transmitting and receiving at least the lossy compressed image data, the decoded image, and the unrestored bit, and
wherein the restoration processing unit determines whether or not to perform the restoration processing for each of blocks in the decoded image in accordance with specific image information, and for a block on which it is determined that the restoration processing is to be performed, performs the restoration processing on the basis of an inference made using a coefficient learned in advance.
