Intelligent infrared camera and intelligent infrared light intensity adjustment method thereof

Abstract

The invention discloses an intelligent infrared camera and an intelligent infrared light intensity adjustment method thereof. The intelligent infrared camera comprises an optical lens, infrared lamps arranged around the optical lens, an optical imaging sensor corresponding to the optical lens, an image processor electrically connected with the optical imaging sensor, and an infrared lamp luminance adjustment module electrically connected with the image processor. In the intelligent infrared camera and the intelligent infrared light intensity adjustment method thereof, the optical lens senses integral light rays, the optical image sensor acquires the light rays and the rear-end image processor processes an image to integrally change an image parameter to change the infrared light intensity according to needs, so the intelligent infrared camera and the intelligent infrared light intensity adjustment method thereof have the advantages of relatively higher practicability and no engineering mounting limitation.

Description

technical field [0001] The invention relates to a security device, in particular to an intelligent infrared camera used in a security system and a method for intelligently adjusting the intensity of infrared light. Background technique [0002] With the development of science and technology, camera devices are widely used in various fields. At present, the security camera industry generally needs day and night monitoring, that is, it has excellent results 24 hours a day, and it can generally have better results under sufficient light during the day. Good effect, the problem is concentrated in the evening. The light at night is generally dark, and the optical imaging sensor that the camera relies on for imaging mainly senses the external light and converts it into an electrical signal. In the case of low light or even no light, it is generally possible to view objects by increasing the exposure time and amplifying the gain value, but at this time the image noise is very larg...

Problems solved by technology

However, this method requires the use of photoresistors. This photoresistor sensing method is first of all that the installation method of the photoresistor directly affects the effect. It is the optical lens area that cannot be installed here, and the photoresistor can only reflect the change of light that hits the photoresistor, resulting in the change of infrared light intensity, which is very limited in engineering applications.

Furthermore, with the photoresistor sensing method, not only must the installation space be reserved for the photoresistor in the camera device, but also the cost of the photoresistor will be increased.
