Photographing processing method and device, photographing method, device and system and terminal equipment

Abstract

A photographing processing method and apparatus, a photographing method, apparatus and system, and a terminal device, the photographing processing method comprising: after receiving a photographing request sent by an application layer, collecting image data; performing pre-hardware processing on the image data to obtain YUV data; performing post-algorithm processing on the YUV data; returning first picture data to the application layer at a first time node during post-algorithm processing, so that the application layer displays a first picture according to the first picture data; after the post-algorithm processing is completed, second picture data are obtained, and the second picture data are returned to the application layer so that the application layer can store the second picture data, and the resolution ratio of a second picture corresponding to the second picture data is larger than that of the first picture. The photographing experience of the user can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of photographing processing, in particular to a photographing processing method and device, and also to a photographing method, device and system, and a terminal device. Background technique [0002] The photo taking process of the camera on the mobile device is as follows: the user presses the camera button, the camera application initiates a photo taking request and sends it to the underlying driver module, and the underlying driver module starts the photo taking process after receiving the photo taking request, which includes collecting image data, processing Collected image data, software post-processing algorithm to process image data, generate jpeg data and a series of operations, return the processed jpeg data to the application, and the application displays the photos. Each processing node runs serially from data collection to jpeg data generation, and the upper layer application will wait un...

Problems solved by technology

In order to achieve perfect picture quality, in addition to continuously improving the hardware image processing pipeline capabilities, it is also necessary to carry various effect processing software algorithms, such as beautification, AI denoising, etc. These software algorithms run on the CPU (Central Processing Unit, central processing unit) , VDSP (Vision DSP, visual information processor), GPU (Graphics Processing Unit, graphics processing unit) or NPU (Neural-network Processing Units, embedded neural network processor), even if hardware acceleration is used to speed up, these algorithms The use of the mobile device will still increase the time-consuming of taking pictures with the camera on the mobile device. The process from data collection to generating jpeg data sometimes takes 2s to 4s. Such time-consuming photography will seriously affect the user's photography experience
