Abstract

An embodiment of the present invention provides an image acquisition device, a device control method, a device, and a storage medium, wherein the image acquisition device includes: a processor, an infrared lamp, and a white light lamp; the processor is used to acquire current acquisition parameters; Wherein, the current acquisition parameters include: magnification, ambient brightness and gain information; the processor is also used to determine the size relationship between the magnification and the preset first threshold and second threshold; according to the magnification The size relationship between the first threshold and the second threshold, as well as the ambient brightness and the gain information, controls the switching status of the infrared lamp and the white light lamp; wherein, the first threshold less than or equal to the second threshold. The embodiments of the present invention can provide light sources through white light lamps and infrared lamps to ensure moderate brightness of the environment where the image acquisition device is located, thereby improving the quality of images collected by the image acquisition device.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an image acquisition device, a device control method, a device and a storage medium. Background technique [0002] With the continuous development of image acquisition technology, image acquisition equipment has been more and more widely used, such as in security monitoring, intelligent transportation and other fields. When an image acquisition device acquires an image, only when the brightness of its environment is moderate can it acquire an image with better quality. [0003] However, in some cases, such as rainy weather, night, etc., the ambient brightness may be relatively dark, resulting in poor image quality captured by the image acquisition device. Therefore, how to ensure the moderate brightness of the environment where the image acquisition device is located so as to improve the quality of the images collected by the image acquisition device is an urgent probl...
