Pickup apparatus and its light source angle control method

Abstract

The present invention is applicable to the field of imaging, and provides an imaging device and a method for controlling the focal length of its light source, wherein the imaging device includes: a zoom camera with multiple imaging focal lengths; a light source with multiple illuminating bodies with different focal lengths; The focal length of the lighting corresponds to the focal length of the camera; the focal length controller of the light source is used to obtain the focal length of the zoom camera, and turn on the corresponding illuminant in the light source according to the obtained focal length of the camera. The present invention adopts a plurality of illuminants whose luminescent focal length corresponds to the imaging focal length of the camera, and turns on the corresponding illuminants according to the current imaging focal length of the camera, which not only saves energy, but also improves the imaging quality.

Description

technical field [0001] The invention belongs to the field of imaging, and in particular relates to an imaging device and a method for controlling the focal length of a light source thereof. Background technique [0002] Camera equipment has been widely used in many fields such as industry, medicine, and transportation. There are many types of camera equipment, among which the cameras used as monitoring equipment are mainly zoom cameras, which can change the focal length to shoot objects with different angles. Zoom cameras are used in the monitoring of banks, docks, urban roads and indoor and outdoor environments have good performance. [0003] The zoom camera needs a light source for lighting to clearly record the surrounding environment, especially in a dark environment, the light source is a necessary device. At present, the luminous angle of the light source of the zoom camera is fixed. When the focal length of the zoom camera changes, the camera angle changes according...
