Abstract

The invention discloses an image data processing method and device, a mobile terminal and a computer readable storage medium. The method is applied to the mobile terminal with more than two cameras. The method comprises the steps that in the process of generating a night scene image, when an application interacts with a hardware abstraction layer, related image buffer blocks carry initial description information used for describing the maximum size; and when the hardware abstraction layer calls the corresponding assembly line flow to process the image buffer blocks, the initial description information carried by the image buffer blocks is changed into the target description information used for describing the real size, so that the mobile terminal can transmit raw images of different sizesin the night scene generation process, and optical zooming is supported during night scene shooting.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image data processing method, an image data processing device, a mobile terminal, and a computer-readable storage medium. Background technique [0002] In order to meet people's shooting needs, existing mobile terminals are often equipped with various types of cameras. A typical example is that a mobile terminal can be equipped with a main camera, a wide-angle camera, and a telephoto camera. In the night scene shooting scene, in order to obtain a clear night scene image, the mobile terminal often collects multiple frames of raw images through a camera, synthesizes them, and then sends them to the driver for format conversion to obtain a YUV image. The above process can usually only be done on the main camera, which makes the existing night scene shooting unable to support optical zoom. Contents of the invention [0003] In view of this, the pr...
