INFRARED CAMERA AND INFRARED LAMP BRIGHTNESS ADJUSTMENT METHOD THEREFOR

摘要

Disclosed are an infrared camera and an infrared lamp brightness adjustment method therefore. The method comprises: when an infrared lamp of an infrared camera is turned on, conducting following processing at a pre-set time period: determining whether there is at least one sub-region with abnormal brightness in N sub-regions of the same size, which constitute a monitoring picture, where N is a positive integer which is greater than 1; and if so, according to a pre-determined parameter of the acquired at least one sub-region with abnormal brightness and a pre-determined parameter of the monitoring picture, determining an infrared lamp adjustment manner, and according to the determined infrared lamp adjustment manner, conducting infrared lamp brightness adjustment so that the at least one sub-region with the abnormal brightness is recovered to be normal. By means of the solution of the present invention, the picture of the monitoring picture can be improved.

1. An infrared lamp brightness adjusting method for an infrared camera, comprising:
after an infrared lamp of the infrared camera is opened, performing processing as follows in each preset time period: determining whether there is at least one sub-region with abnormal brightness in N sub-regions in a surveillance image, the N sub-regions having a same size with each other, N being a positive integer more than 1; if yes, determining an infrared lamp adjustment mode according to a preset parameter of a respective one of the at least one sub-region with the abnormal brightness and a preset parameter of the surveillance image, and adjusting a brightness of the infrared lamp according to the determined infrared lamp adjustment mode until the at least one sub-region with the abnormal brightness returns to normal.
