Abstract

The invention provides a current value adjusting method and device for a lens lamp panel, and the method comprises the steps: determining an environment brightness value of a target image photographedby target monitoring equipment, and a white balance parameter of each statistical block in the target image, wherein the target image comprises N statistical blocks, and N is greater than or equal to1; determining the infrared component ratio of the target image according to the distance between the white balance parameter of each statistical block and a preset white balance parameter, wherein the preset white balance parameter is the average white balance parameter of a first preset image shot by the target monitoring equipment in a closed environment; determining an infrared light brightness value of the target image according to the ambient brightness value and the infrared component ratio; and adjusting the current value of a lens lamp panel on the target monitoring equipment according to the infrared light brightness value. According to the invention, the problem of overexposure of the object shot by the monitoring equipment due to the fact that the object is close to the lamp panel is solved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for adjusting the current value of a lens lamp panel. Background technique [0002] With the improvement of people's safety awareness, monitoring equipment is more common in daily life. For example, monitoring equipment in factories, homes, elevators and traffic roads. In a darker environment, the surveillance camera will turn on the infrared light on its own light board to supplement the light to improve the monitoring effect in a darker environment. However, if there is an object in the monitoring environment that is close to the light panel, due to the infrared reflection, the object will be overexposed, and the brightness of the dark area around the background of the object will become darker, which cannot meet the monitoring requirements. Illegal and criminal events will lead to the loss of important monitoring details. [0003] In the related art...
