ABSTRACT:
A method for adjusting sharpness and brightness of a digital image. In this method, an image function is first inputted into a processor. The image function comprises a plurality of control parameters. Next, the control parameter values of the control parameters are set, and then each of the pixels is sequentially leaded into the image function according to the control parameter value so as to perform the corresponding operation for adjusting the sharpness and brightness of the image. Finally, the adjusted image is outputted. Therefore, the two processes in the prior art, one for adjusting the brightness, the other for the sharpness, are merged into one process so that the design of the hardware circuit is simplified and the required memory space is reduced.
