AI Technical Summary

Technical Problem

Existing video coding technologies face challenges in improving encoding efficiency, image quality, reducing processing volume, and circuit size, as well as selecting appropriate elements or operations such as filters, blocks, motion vectors, and reference pictures.

Method used

An encoding device that determines the size of an image block relative to a predetermined size, deriving correction parameters using surrounding reconstructed images for correction processing, and dividing blocks if necessary to perform consistent correction processing on each unit, thereby reducing memory requirements and improving processing speed.

Benefits of technology

This approach enhances coding efficiency, simplifies processing, reduces memory requirements, and ensures consistent results by deriving correction parameters from surrounding reconstructed images, thus improving processing speed and reducing load.

Abstract

Improve the processing speed during the correction process. [Solution] The encoding device comprises a circuit and a memory connected to the circuit. In operation, the circuit determines whether the size of the image to be processed block is larger than a predetermined size. If the size of the image to be processed block is not larger than the predetermined size, it derives correction parameters using reconstructed images of the area surrounding the image to be processed block and performs correction processing based on the derived correction parameters. If the size of the image to be processed block is larger than the predetermined size, it derives correction parameters using only the reconstructed images of the area surrounding a processing unit of a predetermined size located in the upper left of the image to be processed block (S4001), and performs correction processing based on the derived correction parameters (S4002).
