as described in the above steps S31-S33, different levels of power management low power modes may be turned on according to the magnitude of the obtained first pixel value; for example, if the first pixel value is obtained from one hundredth of the layer, it may be determined whether the first pixel value is greater than ninety percent of the entire layer, for example, if Rgain, Ggain, Bgain of the first pixel value are greater than ninety percent of the entire layer, such as 200 (0-255, black-white) for the first pixel value, and 200 for ninety percent of the entire layer, then it is determined that the color value is currently white; for example, if the first pixel value is 20 (0-255, black-white), and ninety percent of the pixel values of the entire layer are less than or equal to 20, then it is determined that the pixel value is currently a black gray value; when the black and gray value is judged, the user leaves from the camera, and the power management ultra-low-level low-power-consumption mode can be started, so that unnecessary energy consumption is reduced. For another example, by obtaining the first pixel value from twenty percent of the layer, it may be determined whether the first pixel value is greater than ninety percent of the entire layer, for example, if Rgain, Ggain, Bgain of the first pixel value are greater than ninety percent of the entire layer, for example, the first pixel value is 200 (0-255, black-white), and ninety percent of the entire layer are greater than 200, then it is determined that the color value is currently white; for example, if the first pixel value is 30 (0-255, black-white), and ninety percent of the pixel values of the entire layer are all less than or equal to 30, it is determined that the current pixel value is a black gray value, and the intermediate-level power management ultra-low-level low-power mode may be turned on; for another example, by obtaining a first pixel value from fifty percent of the layer, it may be determined whether the first pixel value is greater than ninety percent of the entire layer, for example, if Rgain, Ggain, Bgain of the first pixel value are greater than ninety percent of the entire layer, for example, the first pixel value is 200 (0-255, black-white), and ninety percent of the entire layer are greater than 200, then it is determined that the color value is currently white; for example, the first pixel value is 60 (0-255, black-white), and ninety percent of the pixel values of the entire layer are all less than or equal to 60, then it is determined that the current pixel value is a black gray value, and the middle-level power management advanced low power mode can be turned on.
