Intelligent control strobe light supplementing method and device of camera

Abstract

The invention discloses an intelligent control strobe light supplementing method and a light supplementing device of a camera. The method includes that step one, a luminance signal of continuous snapshot images is calculated by the camera according to a snapshot signal to obtain an average luminance value, whether a light supplementing lamp is switched on or not is determined according to high front lighting luminance threshold value, if the average luminance value is higher than the threshold value, an on-off signal is output to the light supplementing lamp, a power source of the light supplementing lamp is automatically turned off, and if the average luminance value is lower than or equal to the threshold value, the power source of the light supplementing lamp is automatically turned on; and step two, when the light supplementing lamp is switched on, the average luminance value of the snapshot images is calculated again, if the average luminance value is in the optimal luminance range of the snapshot images, the luminance signal of the camera and a synchronization pulse signal of the light supplementing lamp are not required to be adjusted, if the average luminance value is lower or higher than the optimal luminance range of the snapshot images, the output increased or decreased luminance signal of the camera and the increased or decreased synchronization pulse signal of the light supplementing lamp are adjusted, and the adjusted average luminance value is in the optimal luminance range of the snapshot images. By means of the intelligent control strobe light supplementing method and the light supplementing device of the camera, the light supplementing effect and efficiency are improved.

Description

technical field [0001] The invention relates to camera supplementary light technology, in particular to a camera control stroboscopic supplementary light method and device. Background technique [0002] In a low-light environment, non-low-light high-definition cameras cannot effectively image in areas with insufficient light, or the picture is noisy and the picture quality is poor. Generally, when the light changes significantly for high-definition cameras, the parameters of the camera and the fill light cannot be updated in real time, and the image quality varies greatly in different time periods and when the weather changes. Image quality is always unsatisfactory. [0003] In order to make up for the lack of illumination of high-definition cameras in low-light environments, fill lights are generally used to assist in illuminating the camera shooting area. The fill light usually adopts LED strobe light with constant brightness or white light with constant brightness. Thi...
