[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.

[0063] see image 3 , image 3 It is a flow chart of the shooting and focusing method provided by the embodiment of the present invention, such as image 3 As shown, the method is applied to a mobile terminal with a radar device and a touch screen, comprising the following steps:

[0064] Step 301. After starting the camera, when a touch operation on the touch screen is detected, acquire a touch position of the touch operation.

[0065] 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. After starting the camera, the mobile terminal can detect the user's touch operation on the touch screen, and can acquire the touch position of the touch operation.

[0066] Step 302, if the touch position is located in the shooting button area, determine the object with the closest distance to the camera as the target object.

Abstract

Examples of the present invention provide a shooting focus method and mobile terminal, where the method is applied to a mobile terminal with radar device, including: determine the target object after starting the camera;The target distance value of the camera is focused.In this way, the embodiments of the present invention obtain the distance value of the target object to the camera through the radar device, and then focus on the target object according to the distance value.Because the radar device uses electromagnetic waves to calculate the distance of the target and object characteristics, it is not limited to the brightness of environmental light.It can be seen that the shooting focusing method of the embodiment of the present invention achieves the purpose of accurate focusing on weak light conditions.

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...
