Abstract

The present invention proposes a dual-camera zoom processing method, device, and mobile terminal, wherein the dual-camera zoom processing method includes: detecting that the user starts the main camera when the camera is turned on, and detecting whether the user triggers the zooming operation; if the If the user triggers the zooming operation, the secondary camera is started, and a composite preview image is generated according to the first preview image obtained by the main camera and the second preview image obtained by the secondary camera; when it is detected that the user stops the zooming During operation, determine the proportion value of the first preview image and the second preview image in the corresponding composite preview image; control the dual camera according to the proportion value of the first preview image and the second preview image working status. The zoom processing method of the dual camera of the present invention can reduce power consumption while ensuring the user's focusing experience and photographing effect, and effectively improve the available working time and working efficiency of the device.

Description

technical field [0001] The present invention relates to the technical field of photographing processing, in particular to a zoom processing method, device and mobile terminal for dual cameras. Background technique [0002] Currently, more and more mobile terminals can implement a zoom function through dual cameras. Among them, the dual-camera design is mainly composed of a wide-angle camera and a telephoto camera. The principle of realizing zooming is: after opening the camera, enter the wide-angle camera (also called the main camera) and the telephoto camera (also called the sub-camera) at the same time, and synthesize the pictures of the two cameras for the user to preview. When users want to use the zoom function, they can zoom in through the zoom-in box on the touch screen. At this time, the image ratio of the main camera will gradually decrease, and the image ratio of the sub-camera will gradually increase, and the composite display will be performed to achieve zooming...
