Embodiment Construction

[0039] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0040] It should be noted that ZSL refers to zero-delay photography, which is mainly to reduce the time delay caused by traditional photography methods, so that users can obtain images at the moment of taking pictures. In actual implementation, the current ZSL camera solution is that after the camera starts to preview, the camera sensor starts to output data frames. Generally speaking, the latest few frames (such as 5 frames, 8 frames, etc.) will be used as the frame data of the snapshot. , is stored in the cache area such as the cache queue (buffer) of DDR (Double Data Ra...

Abstract

The invention relates to an image processing method, an image processing chip, an application processing chip and electronic equipment, and the image processing method comprises the steps: obtaining a continuous frame image, and carrying out the variation parameter analysis of the continuous frame image, so as to segment the current frame image into a plurality of image regions; selectively caching each image region of the current frame image to obtain cached image data; and when a photographing request is received, the cached image data being sent to the application processing chip. Therefore, on the basis of ensuring the photographing effect, the cached data volume and the data transmission pressure are reduced, so that the system resource occupation is reduced, and the image transmission processing efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image processing method, an image processing chip, an application processing chip and electronic equipment. Background technique [0002] In the current photographing scheme, it is mainly divided into two categories: traditional photographing scheme (non-ZSL) and ZSL (Zero Shutter Lag, zero-delay photography). The multi-frame cache of frame data, when there is a photo taking request, the cached data frame is transmitted to the backend, and the backend performs frame picking processing to select the appropriate image frame for subsequent image processing to generate the final photo image. However, during the storage and transmission of image data, since the entire frame data is stored, a large amount of system resources will be occupied and the efficiency of image transmission and processing will be affected. Contents of the invention [0003] Based on thi...
