Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0038] At present, in order to obtain high-quality night imaging pictures, day mode and night mode are generally integrated inside existing cameras. For this kind of camera, switching between day and night modes is a very important function, which is related to the quality of imaging images. In the existing day-night mode switching process, specifically, the visible illuminance of the imaging picture is determined first, and then whether to perform day-night mode switching is furthe...

Abstract

The present application discloses a camera and a day-night mode switching method, device, equipment, and medium thereof. The method includes: if the current camera mode is the night mode, determining the color temperature value of the current imaging picture; using the color temperature value and a color temperature value based on the current imaging picture The infrared light contribution rate of the picture brightness obtained from the white balance statistical information determines the visible illuminance of the current imaging picture, and uses the magnitude relationship between the above-mentioned visible illuminance and the first preset illuminance threshold to determine whether to switch the current night mode to the daytime mode. In the process of determining the visible illuminance in the night mode, the present application not only considers the influence of the infrared light contribution rate obtained based on the white balance statistical information on the visible illuminance, but also further considers the effect of the color temperature value of the imaging screen in the current night mode on the visible light Therefore, the degree of deviation from the actual visible illuminance is reduced, and the problem of repeated switching between day and night modes is effectively solved.

Description

technical field [0001] The present application relates to the field of camera technology, in particular to a camera and a day-night mode switching method, device, equipment, and medium thereof. Background technique [0002] Currently, with the continuous growth of the security market, more and more cameras are used to monitor the surrounding environment of various places. When the early cameras work in the daytime, the collected imaging images usually meet the actual needs of users, but once at night, the quality of the obtained imaging images is poor, and it is difficult to meet the actual needs of users. For this reason, two working modes are generally integrated inside the existing cameras, one is a daytime mode, and the other is a nighttime mode. Among them, when the camera turns on the night mode, it will project infrared light to the surrounding environment, and allow the infrared light to enter the image sensor through the lens, thereby increasing the light intensity...
