Problems solved by technology
[0003] However, the internal components of the camera are usually deployed in a concentrated manner at the front end of the camera, so there will be mutual occlusion between the components deployed in the front due to space competition
[0004] In order to avoid this kind of occlusion, it is difficult to provide free and flexible deployment space for the light source lamp beads of the fill light module. As a result, not only the fill light effect of the fill light module is not good, but also it is easy to cause the light source of the light bead to the imaging module. The imaging field of view leaks light, which leads to poor imaging effect

The invention discloses a video camera. Based on the present invention, the cylindrical main housing of the camera can have a front cylindrical cavity and a rear cylindrical cavity separated by a mounting partition, wherein the supplementary light module can be installed in the front cylindrical cavity in a substantially exclusive manner, thereby enabling Avoid occlusion and avoidance caused by the space competition of the supplementary light module, so that the light source lamp beads of the supplementary light module can be flexibly deployed in the exclusive space surrounding the imaging field of view of the imaging module, which helps to improve the performance of the supplementary light module. The fill light effect provided by the camera. Moreover, by setting the light-blocking boss on the installation partition, a closed and surrounding optical path block can be formed between the supplementary light module and the lens escape hole, thereby preventing light leakage from the supplementary light module to the imaging field of view of the imaging module. The video camera disclosed by the present invention can further have the functions of adjustable shooting angle, touch adjustment function of supplementary light brightness and extended function of automatic auxiliary focusing.
Description
technical field [0001] The invention relates to the assembly technology of a video camera, in particular to a video camera with a supplementary light function. Background technique [0002] In addition to the imaging module, the video camera usually can also have a supplementary light module. In particular, in scenes with specific requirements for ambient brightness during imaging, the supplementary light effect provided by the supplementary light module for the camera is particularly important. [0003] However, the internal components of the camera are usually deployed in a concentrated manner at the front end of the camera, and thus, the components deployed in a centralized manner in the front part may be mutually occluded due to space competition. [0004] In order to avoid this kind of occlusion, it is difficult to provide free and flexible deployment space for the light source lamp beads of the fill light module. As a result, not only the fill light effect of the fill...
