Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The day and night mode switching method of the camera described in the embodiment of the present invention is mainly used to solve the problem that in the prior art, a photosensitive sensor needs to be installed in the camera to detect the illuminance information. hardware cost. Moreover, the camera designed for smart home applications requires that the infrared fill light cannot be seen on the outside, so its glass will use a black filter design, which will cause the photosensitive element to accurately obtain the outside world through the glass. changes in illuminance.

Abstract

The invention is applicable to the field of security and protection, and provides a method and a device for switching day and night modes of a camera. The method comprises steps as follows: acquiring current adjustment parameters of the camera and/or image content information of the camera; finding an illuminance characteristic value corresponding to the current adjustment parameters of the camera and/or the image content information of the camera; switching the day and night modes according to the illuminance characteristic value and a preset day-and-night-mode switching threshold. According to the method and the device, the day and night modes are switched through software monitoring, so that problems that the day and night modes are required to be switched by the aid of hardware circuits and photosensitive components and photosensitive sensors are inconvenient to mount in the prior art are solved, the cost is reduced, no photosensitive sensor is required to be arranged on the camera, and the consistency of product structures is improved.

Description

technical field [0001] The invention belongs to the field of security protection, and in particular relates to a method and device for switching between day and night modes of a camera. Background technique [0002] In the field of security monitoring, surveillance cameras are required to obtain better image effects in low-light and dark conditions. For example, it is still required to obtain clearer images at night, which requires automatic switching to Night mode, by removing the infrared filter and turning on the infrared fill light to increase image clarity. [0003] In order to achieve effective switching between day and night mode, light-sensitive optical components are generally added in front of the camera lens, and infrared light interference is filtered out at the front of the photosensitive components, only visible light is received, and then the characteristic value after quantization and amplification is used as day-night switching The basis for the judgment, w...
