The invention discloses a method and a device for adjusting image property, wherein the method comprises the following steps that: obtaining the image property parameters of a YUV image; and adjusting the image property parameters according to a preset strategy, and obtaining the adjusted image property. After being applied, the method and the device provided by the embodiment for adjusting the image property omit two times of module conversion of YUV to RGB and RGB to HSV, prevent the problems of excessive calculation and to many consumed resources when the image property of the YUV image is adjusted, so that the occupied resources during the adjustment are very few because the property of the YUV image data is directly adjusted, thereby greatly improving the adjustment efficiency. In addition, the embodiment increases methods for dynamically adjusting the brightness of the image and improves the video effect of image adjustment. Through test and comparison, the adjustment effect of the ...

The invention discloses a day and night video detecting method and a day and night video detecting device. The method comprises: extracting a background image from a preset reference area; recording the brightness average value of the background image in a statistic period; performing smooth treatment on the recorded brightness average values of a plurality of continuous statistic periods; and determining the change tendency of the brightness average values of the background image according to the recorded brightness average value data of the plurality of continuous statistic periods. The invention also discloses a day and night video detecting device. The method and the device can reduce the probability that the feature data in the reference region are interfered and improve the stability of a detection result.
