Method for switching sun vision and night vision of web camera image

Abstract

The invention provides a method for switching day vision and night vision of a web camera image. An image brightness algorithm is used for identifying images to switch working modes of the camera in the daytime and at night to replace a photoresistor or a photosensitive diode to judge the working modes of the camera in the daytime and at night so as to make the camera switching working mode stable, so that the problem that the camera working mode is inaccurate under the backlight condition is solved, a photoresistor or a photosensitive diode of camera hardware is abandoned, the cost is reduced, and environmental protection and nature are achieved; and meanwhile, no hole needs to be formed in the appearance of the product, so that the product is more attractive and diverse in appearance design.

Description

technical field [0001] The invention relates to the field of video security monitoring, in particular to a method for switching between day vision and night vision of network camera images. Background technique [0002] In the field of video security monitoring, with the development of network technology and the increasingly diverse needs of users, 24-hour uninterrupted live broadcast and video recording are required in various scenarios for safety or real-time understanding of on-site conditions. [0003] Almost all cameras in camera night monitoring use photoresistors or photodiodes to judge the working environment of the camera. When the light at night is low, the photosensitive device detects the night, and the infrared light is turned on. At this time, the camera uses infrared visible light to cooperate with the optical The filter presents users with high-definition night video. However, as users use more and more fields of video security monitoring, various applicatio...
