Terminal device and depth-of-field controlling method therefor

Abstract

The present invention discloses a terminal device and a depth-of-field controlling method therefor. The depth-of-field controlling method comprises: A, setting a device type to register a light sensor for assisting a depth-of-field effect; B, generating a node file and saving a preset luminance range of ambient light to the node file; and C, detecting a current luminance value of the ambient light, and determining to implement a depth-of-field algorithm when the luminance value of the ambient light is within the luminance range of ambient light by the light sensor. According to the terminal device and the depth-of-field controlling method therefor disclosed by the present invention, the light sensor is used to replace a camera that is added in the prior art, so as to perform object sheltering detecting, a CPU that supports dual ISP channel is not needed, thereby reducing CPU costs and software complexity of the terminal device, reducing higher loads caused by the dual ISP data processing on the system, and improving depth-of-field operation speed and effects.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment, in particular to a terminal equipment and a method for controlling the depth of field thereof. Background technique [0002] At present, mobile phones can also take pictures with depth of field effects. The so-called depth of field is that when the focus is on a certain point, the front and back are still clear; it can determine whether to blur the background to highlight the subject, or to shoot a clear background. In the prior art, it is necessary to install two rear cameras (cameras) in the mobile phone, that is, to add a new rear camera on the basis of the existing rear camera to detect whether there is an object occlusion, and judge whether to start it according to the occlusion situation. Depth of field blur effect. Since these two rear cameras need to work at the same time, there are certain requirements for the CPU (Central Processing Unit, central processing unit) of...
