Image processing method, device and equipment

Abstract

The embodiment of the invention provides an image processing method, device and equipment, and the method comprises the steps: obtaining a plurality of images obtained through the photographing of thesame scene, and enabling the photographing focuses of the plurality of images to be different; determining at least one first image in the plurality of images; acquiring an image parameter corresponding to each first image; and performing compressed encoding on the at least one first image and the image parameter corresponding to each first image. Image coding efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of image coding, and in particular, to an image processing method, device, and equipment. Background technique [0002] Multiple images with different focal points may be obtained by zooming in on the same scene, and the multiple images with different focal points may be called a focus stack image sequence. [0003] When storing or transmitting the focus stack image sequence, in order to save storage resources or transmission time, multiple images can be compressed and encoded. In the prior art, the method of video compression is usually used to compress and encode multiple images, and the data amount of the area that changes (for example: different brightness, different chrominance) in adjacent images is retained, and the data of the area that does not change is removed. amount, thereby reducing the data volume of multiple images, so that multiple images occupy less resources in the process of ...

AI Technical Summary

Problems solved by technology

However, when the change of adjacent images is only the focus, the brightness or chrominance does not change, and the method of video compression cannot identify this change well, resulting in low coding efficiency
