[0024] see figure 1 , figure 1 It is a flow chart of the shooting and focusing method provided by the embodiment of the present invention, such as figure 1 shown, including the following steps:

[0025] Step 101, after starting the camera, determine the target object.

[0026] In this step, when the camera is started, the mobile terminal can control the camera to collect images of objects within the shooting range, and can display the collected images in the imaging preview area. The above-mentioned process of determining the target object can be completed automatically by the mobile terminal, or it can be completed by the mobile terminal according to the user's operation instruction; it can be based on the existing technology for determining the target object, or it can be based on a new technology for determining the target object . In this regard, the embodiment of the present invention does not make a limitation.

Abstract

The embodiment of the invention provides a photographing focus method and a mobile terminal. The method is applied to the mobile terminal with a radar device. The method comprises the steps of determining a target object after a camera is started; and carrying out focus according to a target distance value obtained by the radar device from the target object to the camera. In this way, according to the embodiment of the invention, the distance value from the target object to the camera is obtained through the radar device, and the focus is carried out on the target object according to the distance value. Information such as the distance to the target and an object feature is calculated by the radar device through utilization of an electromagnetic wave, so the influence of environment illumination brightness is eliminated. Visibly, according to the photographing focus method provided by the embodiment of the invention, the focus is carried out accurately under a weak light condition.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a shooting and focusing method and a mobile terminal. Background technique [0002] At present, the commonly used focus methods for mobile terminal shooting mainly include phase detection auto focus (PDAF, Phase Detection Auto Focus) or laser focus (LDAF, Laser Diode Auto Focus). Among them, the phase-type focusing needs to use the shaded pixels on the photosensitive element for phase detection, which requires relatively high light intensity; the laser-type focusing calculates the distance of the target object based on the time difference between emitting and receiving infrared rays. The bottom focus effect is poor. It can be seen that the current shooting focusing method of the mobile terminal has the problem of poor focusing effect under low-light conditions. Contents of the invention [0003] Embodiments of the present invention provide a shooting and focu...
