Abstract
The present invention discloses an image processing method and an image processing system adopting the same. The method includes the steps of: (a) obtaining a pixel array representing an image; (b) segmenting the pixel array into two or more non-overlapping regions; (c) identifying a capacitor discharging rate of each of the regions; (d) generating a pulse width modulation (PWM) signal when a voltage level dropping of a capacitor exceeds a predetermined threshold; and (e) applying exposure parameters to the regions according to the capacitor discharging rate of the regions, respectively, wherein the exposure parameter applied to one of the regions is different from the exposure parameter applied to at least another one of the regions.
