Embodiment Construction
[0057]In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0058] In the field of security monitoring, in order to adapt to various lighting conditions, the automatic exposure time range of the ISP of the camera equipment is generally 1 / vin frame rate to 1 / 32000. Surveillance camera equipment requires that it can truly restore the image of the actual scene when the lighting conditions are good. In order to make the color true without color cast, an infrared filter device is generally added in front of the image sensor to eliminate the influence of infrared light on the color cast of the image. When the lighting conditions are poor,...

The present application relates to a camera mode switching optimization method, device, computer equipment and storage medium. The method includes: determining the switching target camera mode; according to the illumination requirement corresponding to the target camera mode, turning off the first light control element in the camera device that is in the open state and adjusting the initial exposure mode and recording the number of adjusted frames; When the adjusted frame number reaches the preset frame number, the second light control element in the closed state is turned on in the camera device, and when the second light control element is turned on for a preset time, the exposure mode is restored to the initial exposure mode. According to the switching target camera mode, control the opening and closing sequence of the first and second light control elements, adjust and control the exposure mode, and increase the processing time delay in the adjustment process, which solves the problem that the monitoring screen is prone to failure when the mode is switched. The problem has achieved the effect of mode switching optimization.
Description
technical field [0001] The present application relates to the field of security technology, in particular to a camera mode switching optimization method, device, computer equipment and storage medium. Background technique [0002] With the development of security monitoring technology, day and night surveillance cameras have emerged to achieve uninterrupted target monitoring day and night. [0003] In order to adapt to the different lighting conditions of day and night, and the color is true without color cast, an infrared filter device is generally added in front of the image sensor of the day and night surveillance camera to eliminate the influence of infrared light on the color cast of the image. In order to obtain a clearer image at night, it is required that the camera can automatically switch to the night mode under low light conditions, by removing the infrared filter element and turning on the infrared supplementary light element to increase image clarity. [0004] ...
