The application discloses a supplementary light control method and device for an image acquisition device, and an image acquisition system. Wherein, the method includes: starting the supplementary light equipment for supplementing light to the image acquisition device; acquiring the gray value of the picture captured by the image acquisition device; comparing the gray value with the first threshold; and gradually adjusting the brightness of the supplementary light device according to the comparison result. Fill light intensity until the gray value of the picture is less than the first threshold. This application solves the technical problem that if the image clarity captured by the camera meets the requirements, the required light intensity is less than the fixed light intensity of the supplementary light device, resulting in waste of power consumption of the supplementary light device.
Description
technical field [0001] The present application relates to the field of cameras, in particular, to a supplementary light control method and device for an image acquisition device, and an image acquisition system. Background technique [0002] With the enhancement of people's security awareness, home security cameras are becoming more and more popular, and many home appliances will also be equipped with cameras for human body recognition in home scenes. At night, the camera cannot detect a clear camera picture, so infrared LED lights are generally used for supplementary light. However, the current fill-in light control method cannot adjust the fill-in light intensity, causing the picture to sometimes be bright, and sometimes unable to fill in the light effectively, resulting in unclear pictures and poor imaging effects. Furthermore, some biometric functions cannot be realized. In addition, when the supplementary light equipment supplements the camera with a relatively high a...
