Example Embodiment
[0031] In the embodiment of the present invention, when the brightness value of the image belongs to the brightness range, it is further determined whether there is an overexposed area in the image, and when there is an overexposed area, the automatic exposure parameter value is adjusted to reduce the exposure of the image, thereby reducing the exposure of the image. exposure to improve the display effect of the image. And when there is no overexposed area, the automatic exposure parameter value is adjusted to increase the exposure of the image and improve the display effect of the image.
[0032] The images in this embodiment include pictures and video images.
[0033] see figure 1 , the main method flow of automatically exposing the image in this embodiment is as follows:
[0034] Step 101: Obtain the brightness value of the image. The brightness value of the image is the average brightness value of the entire image, or the weighted average brightness value of the entire ...
