Abstract

The invention provides a zoom processing method and a device for dual cameras and a mobile terminal. The method comprises steps: a main camera is started when the user is detected to start the camera, and whether the user triggers zoom magnification operation is detected; if the user triggers the zoom magnification operation, an auxiliary camera is started, and according to a first preview image acquired by the main camera and a second preview image acquired by the auxiliary camera, a merged preview image is generated; when the user is detected to stop zoom magnification operation, the occupancy ratio of the first preview image and the second preview image in the corresponding merged preview image is determined; and according to the occupancy ratio of the first preview image and the second preview image, the working states of the dual cameras are controlled. According to the zoom processing method for the dual cameras, power consumption is reduced while focus experience of the user and photographing effects are ensured, the available working hour and the working efficiency of the device can be effectively enhanced.

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...
