Embodiment Construction

[0034] The process flow of the ambient light frequency detection method in a preferred embodiment of the present invention is as follows: figure 1 As shown, the following steps are included: S1, enter the high-speed camera mode; S2, in the high-speed camera mode, shoot the current ambient light source according to the preset camera frame rate, and display the captured video image; S3, detect whether the video image is Flicker occurs; S4, if it occurs, it is considered that the frequency of the current ambient light source is lower than the preset camera frame rate; S5, otherwise, it is considered that the frequency of the current ambient light source is higher than the preset camera frame rate. In this way, when the flickering of the video image screen is detected, the user can be prompted that the current ambient light quality is poor, and activities such as surfing the Internet and reading books cannot be carried out in this environment for a long time, or the user can be pro...

Abstract

The invention relates to a method, a device and a mobile terminal for detecting an ambient light frequency. The method comprises the following steps of: photographing a present ambient light source in a preset photographing frame rate in a high speed photographing mode, and displaying a photographed video image; detecting whether a video image has flicker or not, if so, judging that the frequency of the present ambient light source is lower than the preset photographing frame rate; or else, judging that the frequency of the present ambient light source is higher than the preset photographing frame rate. When the video image having flicker is detected, a user can be promoted that the present ambient light is poor in quality, so that people can not have activities such as surfing the Internet and reading a book in such environment for long time, or the user is promoted to select and purchase a light source having better quality, and meanwhile, the user is promoted to pay attention to the eye health and protect eyes to prevent shortsightedness.

Description

technical field [0001] The present invention relates to the field of communication technology, and more specifically, to a method, device and mobile terminal for detecting ambient light frequency. Background technique [0002] With the development of science and technology, the application functions of mobile terminals are becoming more and more abundant. The camera function has become an indispensable function in mobile terminals. In previous mobile terminal devices, due to the limitations of hardware devices such as camera sensors and CPUs, the shooting of dynamic images can only reach 720P 30 frames per second or 1080P 30 frames per second. The frame rate of the frame, so that the recorded dynamic picture cannot see a relatively complete track of the moving object when it is played at a slow speed. In the existing mobile terminal equipment, through the use of high-speed camera sensors combined with software technology, the mobile terminal can shoot dynamic images at a fr...
