Problems solved by technology

[0003] However, in practical applications, because the dome cover and lens surface of the dome surveillance camera may reflect the light from the outside or inside of the surveillance camera, the reflected light or the reflected image formed by it will cause halos Or glare, which affects the quality of the video recorded or captured by the surveillance camera, which may cause difficulties in image recognition

Abstract

The invention provides an image capture device. The image capture device comprises a base, an image capture unit and a hemispherical cover body, wherein the image capture unit is arranged on the base and provided with a lens, the lens is provided with a surface, and the hemispherical cover body is arranged on the base and coats the image capture unit. A light axis is defined by the lens of the image capture unit, a focal point and a center are defined by the hemispherical cover body and intersect with the light axis, and the focal point is arranged on the surface of the lens. According to the image capture device provided by the invention, the focal point is arranged on the surface of the lens, so that reflected images formed by light rays reflected by the surface of the lens and the internal surface of the hemispherical cover body can be imaged at infinity as far as possible, and halos or glares formed by the reflected images are eliminated or reduced.

Description

technical field [0001] The invention relates to an image capture device, especially an image capture device with a hemispherical cover that can eliminate or reduce halo or glare. Background technique [0002] At present, the use of surveillance cameras has become quite popular, and they are widely installed in various places indoors and outdoors, and the recorded or photographed images can be used for various purposes. Among the many forms of surveillance cameras, hemispherical surveillance cameras are widely installed indoors, such as in elevators, because they are smaller and lighter than ordinary cylindrical surveillance cameras. [0003] However, in practical applications, because the dome cover and lens surface of the dome surveillance camera may reflect the light from the outside or inside of the surveillance camera, the reflected light or the reflected image formed by it will cause halos Or glare, affecting the quality of images recorded or captured by surveillance c...
