Light source brightness control system and control method

Abstract

The invention discloses a light source brightness control system and a light source brightness control method. The light source brightness control system comprises a camera, a control device and at least one strip-shaped light source. The strip-shaped light source comprises a plurality of light source monomers which are arranged in a straight line and are used for emitting the light to a shootingtarget. The camera is used for carrying out shooting and imaging on the shooting target so as to form a light-emitting brightness image corresponding to the strip-shaped light source. The control device is used for sequentially controlling the strip-shaped light source to emit the light during the brightness adjustment of the light source, and carrying out image treatment on the light-emitting brightness image. In this way, the light-emitting brightness of each light source monomer of the corresponding strip-shaped light source is controlled according to the image treatment result, so that thestrip-shaped light source can uniformly illuminate the shooting target. According to the invention, the brightness of a shot image can be more uniform.

Description

technical field [0001] The invention relates to the field of camera technology, in particular to a light source brightness control system. Background technique [0002] When shooting an object with a camera, currently a supplementary light component (such as an LED light) is generally used to supplement light on the object, but since a supplementary light component is used to supplement light on an object, no matter how the control of the supplementary light component Luminous brightness, the image of the object captured by the camera is that the part of the object close to the light-filling element is brighter, while the part of the object far away from the light-filling element is darker, that is, the light-filling element cannot illuminate the object uniformly, which will make the image appear brighter. The brightness of the image of the object is not uniform enough. Contents of the invention [0003] In view of the above problems, the object of the present invention i...
