Abstract
A system for adjusting a sensitivity of a camera module includes a memory unit configured for storing a plurality of pre-initialized pixel adjusting maps; an image capturing unit configured for capturing an image from the camera module and acquiring pixel values of the image to determine a pixel value range of the pixel values; a comparison unit configured for comparing the pixel range with the input-ranges of the pixel adjusting maps to determine which one of the input ranges of the pixel adjusting maps the pixel value range of the image; and an adjusting unit configured for adjusting the pixel value of the image to adjusting the sensitivity of the camera module according to the determined pixel adjusting map and outputting adjusted pixel values. The system can not only breakthrough the limit of the self-character of the amplifier, but also decrease noise in course of adjusting the sensitivity of the camera module.
