Description

[Technical field]

[0001] The utility model relates to the technical field of image lighting control circuits, in particular to a high-resolution remote sensing image lighting control circuit with reasonable circuit design and outstanding application effect. [Background Technology]

[0002] The specific operation process of the imaging device generally needs to be carried out under a certain lighting environment. Different lighting environments have a greater impact on the work of the imaging device and may directly affect the quality of the content. For example, when the light intensity is very low, the light color quality is very poor, and the color rendering is very low, this requires that the light-emitting device that cooperates with the imaging device can generate appropriate output light according to the ambient light of the target area. However, in the prior art, the light emitted by the light-emitting device is often unable to be associated with the ambient light of the target area, which results in poor matching between the light emitted and the target area, affecting the actual viewing experience.

[0003] For example, the utility model patent with application number CN2015206989417 and patent name "Light Generator, Imaging Device and Imaging System" specifically discloses a light generator for providing auxiliary lighting for imaging devices, including a light source for generating light, a light source driving circuit connected to the light source and driving it to emit light, and a control circuit connected to the light source driving circuit and outputting a control signal thereto, wherein the light source driving circuit drives the light source to emit light according to the control signal, and further includes a spectrum detection device connected to the control circuit and used to detect the spectral information of the target area and send the spectral information to the control circuit, wherein the control circuit generates the control signal according to the spectral information. Since the spectral detection device is provided, the spectral information of the target area can be obtained, which provides a basis for parameter setting for subsequent lighting. The utility model also discloses an imaging system and imaging device.

[0004] The problem with the above-mentioned prior art is that, in specific applications, it is not possible to utilize better lighting control to achieve a higher resolution visual image effect.

[0005] Based on this, it is necessary to start with the existing technology and make further improvements and enhancements. [Contents of the utility model]
