Abstract

The invention discloses a shooting method by use of cameras with different focal lengths and a terminal. A high-quality image can be still acquired under a condition that the lens module is not increased. The method comprises the following steps: starting a first camera for focusing before shooting; judging whether to start a second camera for focusing according to the imaging effect of the first camera after focusing, wherein the focal length of the second camera is less than that of the first camera; if the second camera is judged to be required to be started for focusing, starting the second camera for focusing; and shooting a focused object by the camera after focusing; as the focal length of the second camera is less than that of the first camera, when the object in a close range is shot, the second camera is only started for focusing and shooting, and the high-quality image can be acquired; and besides, the lens is ensured not to protrude out of the terminal, so that the space of the lens module is reduced, the terminal of the camera can be manufactured to be light and small, and the process requirements of a user for the terminal can be met.

Description

technical field

[0001] The invention belongs to the field of image processing, and in particular relates to a method and a terminal for taking pictures using cameras with different focal lengths. Background technique

[0002] The development of intelligent terminal technologies such as smartphones and tablet computers has made these terminals more and more powerful, far beyond the single function of communication. It is no exaggeration to say that smart terminals such as smartphones are no longer simple communication tools, but handicrafts that integrate leisure, entertainment and communication functions. For example, general smart phones are equipped with cameras to realize the functions of taking pictures and / or video recordings.

[0003] An important index to measure the shooting function of the above-mentioned smart terminal is the clarity of the image. According to the imaging principle in the optical field, a telephoto (or far-focus) camera can clearly capture distan...
