Light supplement device and photographing system

Abstract

The present invention provides a supplementary light device and a shooting system. The supplementary light device includes a first light-emitting structure, which is used to emit light in the supplementary light band when the first light-emitting structure is turned on, wherein the supplementary light band belongs to the first range , wherein, the relative visual acuity of the human eye corresponding to the wavelength in the first range is less than or equal to the first threshold, and the first threshold is less than 1; it also includes a first switch module, which is used for when the current ambient brightness is lower than the preset first threshold In the case of a brightness threshold, the first light emitting structure is controlled to be turned on. According to the present invention, since the first light-emitting structure is turned on by controlling the ambient brightness, and the relative visual acuity of the human eye corresponding to the light in the supplementary light band is less than or equal to the first threshold, the first threshold is less than 1, that is, the light in the supplementary light band is less than or equal to the first threshold. The sensitivity of the human eye is low, so it can solve the problem of how to supplement light in a low-brightness environment, and achieve the technical effect of effectively reducing the discomfort caused by the supplementary light system to the human body and the light pollution to the environment.

Description

technical field

[0001] The present invention relates to the field of optics, and in particular, to a light-filling device and a photographing system. Background technique

[0002] In the field of intelligent recognition, the realization of night image recognition requires a strong enough fill light to obtain an image that can be recognized, which will greatly reduce the human comfort of people who are close to the fill light, and will also cause serious problems. of light pollution.

[0003] At present, the main methods of night recognition are short-range white light supplementary light + recognition or long-distance infrared supplementary light (black and white). The low-glare technology in the related art mainly supplements the light by reducing the final light intensity of the supplementary light, such as the method of using frosted to homogenize the output surface light, increasing the light-emitting area or reducing the power of the lamp; but the disadvantage of synch...
