Embodiment Construction
[0041] 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 with reference to the accompanying drawings and examples.
[0042] In the embodiment of the present invention, motion detection is firstly used to obtain background regions in two consecutive frames of images. Then, calculate the average chromaticity of the background area in two consecutive frames of images, considering that the average chromaticity of the background area is usually only affected by the nature of the actual light source, so when the chromaticity of the background area in two consecutive frames of images When the difference between the average values is greater than or equal to the preset first threshold, it means that the chromaticity average value of the background area in two consecutive frames of images has changed significantly, so it can be determined that the nature of the actual light s...
