Abstract:
1. A device for selecting an image processing function, comprising: an analog-to-digital converting unit outputting a first image in response to an image signal having a first frequency; a resolution-downgrade controlling unit, coupled to the analog-to-digital converting unit, wherein the first image has a resolution, and the resolution-downgrade controlling unit is configured to: a frame buffer unit having a frame buffering function and coupled to the resolution-downgrade controlling unit, wherein when the frame buffering function is enabled under a vertical synchronization frequency of the first image is greater than a predetermined frequency, the frame buffer unit stores and outputs a part of image data of the first image from the resolution-downgrade controller; an over-driving unit having an over-driving function and coupled to the resolution-downgrade controlling unit, wherein when the over-driving function is enabled under the vertical synchronization frequency of the first image is smaller than or equal to the predetermined frequency, the over-driving unit receives and performs an over-driving operation on the first image from the resolution-downgrade controller, and then outputs the first image; a frame synchronization controlling unit, coupled to the over-driving unit, and configured to: a resolution-upgrade controlling unit, coupled to the frame buffer unit and the frame synchronization controlling unit, and configured to: an image processor, coupled to the resolution-upgrade controlling unit, and configured to receive and perform an image process on the second image from the resolution-upgrade controller, and then output a processed image-data information; and a differential signal converting unit, coupled to the image processor, and configured to receive and convert the processed image-data information, and then output a converted differential-signal information to a driving chip of a panel in a display system.
