MOVING IMAGE ENCODING APPARATUS, IMAGE CAPTURING APPARATUS, MOVING IMAGE ENCODING METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM

摘要

A moving image encoding apparatus comprising, an encoding unit, a decoding unit, a filter unit and an offset processing unit wherein the encoding unit performs predictive encoding based on a decoded image having undergone an offset processing and the offset processing unit selects and executes a first offset processing for a low-frequency component image when an image of the block has a feature associated with the low-frequency component image in accordance with a feature of an image of a processing target block, and selects and executes a second offset processing for a high-frequency component image when an image of the block does not have a feature associated with the low-frequency component image.

1. A moving image encoding apparatus comprising:
an encoding unit configured to perform predictive encoding for an encoding target image on a block basis; a decoding unit configured to generate a decoded image by decoding the target image having undergone the predictive encoding; a filter unit configured to apply deblocking filtering to the decoded image; and an offset processing unit configured to perform an offset processing for the decoded image having undergone the deblocking filtering, wherein the encoding unit performs the predictive encoding based on the decoded image having undergone the offset processing by the offset processing unit, and the offset processing unit selects and executes a first offset processing for a low-frequency component image when an image of the block has a feature associated with the low-frequency component image in accordance with a feature of an image of a processing target block, and selects and executes a second offset processing for a high-frequency component image when an image of the block does not have a feature associated with the low-frequency component image.
