CAMERA LENS AND VIDEO CAMERA
Document Type and Number:
WIPO Patent Application WO/2018/064903
Kind Code:
A1
Abstract:
Disclosed, in the embodiments of the present application, are a camera lens and a video camera. A light splitting device is provided in the camera lens to split an incident light into visible light and near-infrared light; and a zooming group lens and a compensating group lens are further provided in the camera lens for achieving zooming and aberration correction. The camera lens is provided in the video camera to separate the visible light from the near-infrared light; a visible light acquisition module is further provided in the video camera to acquire the visible light emitted from the camera lens and convert the visible light into a color signal and a first brightness signal; a near-infrared light acquisition module is further provided in the video camera to acquire the near-infrared light emitted from the camera lens and convert the near-infrared light into a second brightness signal; and a fusion module is further provided in the video camera to fuse the color signal, the first brightness signal and the second brightness signal to output a fused image. Hence, the video camera provided in the solution can process the visible light and the near-infrared light respectively and then perform fusion, thus avoiding color cast due to mixed processing for said lights, and outputting an image under a color mode in a low-light scene.
