Abstract
The disclosure provides an image adjustment device configured to be different modes according to whether the adopted display is a light emitting diode display or a liquid crystal display, and including a duty cycle calculator, an intensity calculator and a compensator. In a first mode, the duty cycle calculator determines a respective type of each segment according to brightness information of each segment, and sets a duty cycle value according to the type of the segment. In a second mode, the duty cycle calculator calculates the duty cycle value according to the brightness information of each segment. The intensity calculator calculates the pixel intensity of the segment based on the duty cycle value and a light diffusion coefficient set. The compensator generates a pixel gain value according to the intensity value of each pixel of the segment, and adjusts the pixel value according to the pixel gain value.
