The utility model discloses a preferred embodiment 2:

the camera that can carry out infrared filtering and switch can realize day night dual-purpose, and its rationale is: in the daytime, natural light enters the image sensor, imaging (near infrared light filtering) is performed through an image processing unit (hereinafter abbreviated as ISP), the infrared filter is switched to a full-spectrum light receiving state under a low-brightness environment, the infrared lamp is turned on, infrared light emitted by the infrared lamp irradiates a shot object and returns to the equipment sensor, and a black and white picture is obtained through ISP processing.

In common daily application, whether to turn on or turn off infrared is determined by judging whether an environmental brightness value (hereinafter referred to as AE value) is lower or higher than a certain threshold value through image YUV data. However, in a certain low-brightness environment, after the infrared lamp is turned on, the brightness value detected by the image sensor is higher than the low-brightness judgment threshold value, and the system may misunderstand that the surrounding environment is bright enough to turn off the infrared lamp; after the infrared lamp is turned off, the system can judge that the AE value is insufficient at once and can be turned on again, and after the system is turned on, the AE value is still judged to be higher than the low-brightness judgment threshold value, the system can turn off the infrared lamp again, and the system is abnormal in work due to circulation, and internal devices can be damaged for a long time.

Thus, the video is divided into 16 × 9-144 regions from horizontal and vertical according to the current video resolution, and each region is numbered from 1 to 144, which is 1,2,15,16,17,18,31,32,56,57,72,73,113,114,127,128,129.130,143,144

The area is a key area. The brightness value of the first region is E1, the brightness value of the eighth region is E8, the absolute value of the brightness difference is Delta E1/8, and a, b, c, d, E and f are set values.

A＝a(△E2/8+△E9/15)/2+a(△E130/136+△E137/144)/2

B＝b(△E17/65+△E65/133)/2+b(△E32/80+△E80/112)/2

C＝c(△E1/72+△E16/73)/2+c(△E129/72+△E144/73)/2

△E＝(A+B+C)/3

Delta Ef as a threshold value

A, b, c are adjusted in different systems. If delta E is larger than delta Ef, the infrared state is obtained. Otherwise in natural light state

In the infrared state, the infrared does not need to be turned off.
