Problems solved by technology

[0002] At present, in the face recognition, vehicle recognition and night color image cameras, due to the serious lack of ambient light at night, most cameras usually use white light for supplementary light, but the light emitted by the supplementary light will not only cause certain glare to people, Moreover, since both the face and the license plate will reflect light of a certain band, it will affect the recognition rate of the face and license plate.

Abstract

The invention discloses a camera. The camera comprises a fill-in light device and a camera shell, the light supplementing light source comprises a main light supplementing part and a mixed color lightsupplementing part, light emitted by the main light supplementing part is located in a first wave band, light emitted by the mixed color light supplementing part is located in a second wave band, andlight emitted by the mixed color light supplementing part and light emitted by the main light supplementing part are mixed to form exposure compensation light. According to the light supplementing light source, the wavelength of the main light supplementing part is adjusted in the first wave band; the recognition rate of the to-be-photographed object is improved; in addition, the color mixing andlight supplementing part is arranged on the basis of the main light supplementing part, and the color of the mixed light mixed with the light emitted by the main light supplementing part is adjustedthrough the light emitted by the color mixing and light supplementing part, so that the color of the exposure compensation light emitted by the light supplementing light source is softer, and glare topeople is avoided.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video camera. Background technique [0002] At present, in the face recognition, vehicle recognition and night color image cameras, due to the serious lack of ambient light at night, most cameras usually use white light for supplementary light, but the light emitted by the supplementary light will not only cause certain glare to people, Moreover, since both the face and the license plate will reflect light of a certain band, the recognition rate of the face and the license plate will be affected. [0003] Therefore, a technical solution is desired to overcome or at least alleviate at least one of the above-mentioned disadvantages of the prior art. Contents of the invention [0004] It is an object of the present invention to provide a video camera that overcomes or at least alleviates at least one of the above-mentioned disadvantages of the prior art. [0005] To a...
