Embodiment Construction

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the related application, not to limit the application. It should also be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings.

[0043] Auto Focus (AF) uses the principle of object light reflection, and the reflected light is received by the sensor charge-coupled device (CCD) on the camera, and processed by a computer to drive the electric focusing device to focus. There are two types of auto focus: one is active and the other is passive.

[0044] At present, when the user turns on the shooting device configured on the terminal, the terminal will complete auto-focusing. The default focus point is in the center of...

Abstract

The embodiment of the invention discloses an image acquisition method, a terminal, a chip and a storage medium. The image acquisition method comprises the steps of determining a photographing mode according to a detected touch operation signal; if the photographing mode is a preset mode, determining a plurality of focal lengths according to a preset step length, and determining a white balance parameter and an exposure parameter at the same time, wherein the preset mode is used for shooting by using different focal lengths; performing shooting processing according to the white balance parameter, the exposure parameter and the plurality of focal lengths to obtain a plurality of frames of images of the current scene, wherein one focal length corresponds to one frame of image; determining a mapping relationship between pixel positions and focal lengths based on the multiple frames of images; and obtaining a target image according to the multi-frame image and the mapping relationship between the pixel position and the focal length.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image acquisition method, a terminal, a chip and a storage medium. Background technique [0002] At present, when the user turns on the shooting device configured on the terminal, the terminal will complete auto-focusing. The default focus point is in the center of the screen. If the user needs to focus on a specific object, the terminal can complete the focusing by receiving the user's click on the screen. Function, it can be seen that the autofocus method can effectively complete the focus processing in most cases. [0003] However, when the terminal is shooting, if the object to be photographed is small, the efficiency of the terminal in focusing will be relatively low, and it will often fail to focus, thereby reducing the shooting efficiency and shooting effect. Contents of the invention [0004] Embodiments of the present application provide an image a...
