Problems solved by technology

When the user uses the zoom function in low light and switches to the telephoto camera, since the aperture of the telephoto camera is relatively small and the amount of light entering is small, in order to keep the brightness of the preview image of the telephoto camera consistent with the brightness of the preview image of the wide-angle camera, the telephoto The ISO and exposure gain of the camera will be increased, resulting in serious noise

Abstract

The embodiment of the invention provides an image processing method and a terminal. The method comprises the following steps: obtaining a brightness value of an image frame in an image collected by a wide-angle camera; if it is detected that a user triggers a preset operation of a zooming function, and the brightness value is smaller than or equal to a preset brightness threshold, performing digital zooming processing on the image, and generating a first preview image, wherein the brightness value of the image frame in the image collected by the wide-angle camera is matched with the brightness value of the first preview image. By adoption of the image processing method provided by the embodiment of the invention, when zooming is carried out in a weak light shooting condition, it is guaranteed that the brightness value of the image frame in the image collected by the wide-angle camera is matched with the brightness value of the first preview image that is finally formed after the zooming processing, and the quality of the first preview image generated by weak light zooming is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and terminal. Background technique [0002] At present, more and more terminals (mobile phones, tablet computers, etc.) have dual cameras, and the terminals can realize zooming through the dual cameras. Among them, the dual camera is mainly composed of a wide-angle camera (main camera) and a telephoto camera (secondary camera). [0003] In the structural design of the terminal, it is usually required that the height of the wide-angle camera module is consistent with the height of the telephoto camera module. Therefore, the aperture of the wide-angle camera will be designed to be larger than that of the telephoto camera. For example, the aperture of the wide-angle camera is designed to be F2 .0, the aperture of the telephoto camera is designed to be F2.8; while in the camera module, the aperture represents the amount of light entering t...
