Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] figure 1 It shows the implementation process of a method for reducing the current when taking pictures provided by the embodiment of the present invention, and the details are as follows:

[0037] Step 101, after detecting that the camera preview mode is turned on, start the face detection function.

[0038] When the camera or camera is turned on to take a picture, the camera captures the scene or people or objects, and then performs a camera preview. After detecting that the camera preview mode is turned on, the face detection function is activated.

[0039] Step 102, performing face dete...

Abstract

The invention belongs to the technical field of cameras, and provides a method and device for reducing a current in the shooting process. The method comprises the steps that when the starting of a camera preview mode is detected, a human face detection function is started; human face detection is carried out on obtained preview data, whether the human face detection is paused or not is determined according to the human face detection result, the power consumption of a handheld device in the shooting process can be greatly reduced by interruptedly starting or pausing the human face detection occupying a large number of CPU operations and under the situation that the human face detection is paused when there is no human face, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of cameras, and in particular relates to a method and device for reducing current when taking pictures. Background technique [0002] With the advent of the era of intelligent mobile terminals, the configuration of mobile terminals (such as mobile phones and IPADs) is becoming more and more powerful, and higher and higher requirements are placed on the battery life of mobile terminals. However, when the existing mobile terminal turns on the camera to take pictures, the mobile terminal consumes power very quickly. The camera basically has the function of face detection. After adding the face detection, the current consumption is faster. The reason is that the system needs to preview The face detection and analysis of the data takes up a lot of calculations of the CPU, so it consumes a lot of power. Contents of the invention [0003] The purpose of the present invention is to provide a method for reducing t...
