1. A method of frame rate conversion comprising:
- receiving a plurality of input frames comprising a previous frame, a current frame and a next frame;
outputting the current frame;
calculating a changing trend between the current frame and the previous frame;
modifying the current frame to generate at least one inserting frame according to the changing trend;
outputting the inserting frame to achieve frame conversion; and
outputting the next frame after outputting the inserting frame.

Abstract
A method of frame rate conversion includes receiving multiple input frames including a previous frame, a current frame and a next frame. A changing trend between the current frame and the previous frame is calculated. The current frame is used for generating one or more than one inserting frame according to the changing trend. The inserting frame is output after outputting the current frame to achieve frame conversion.

7. A semiconductor display driver device connected to a video processor for processing a series of input frames, comprising:
-
a detector for detecting whether the video processor is instructing the image processing apparatus to run in a static mode, wherein in the static mode, no frame change is occurred; a frame buffer; a control device for storing one input frame in the frame buffer if the static mode is determined; and an image signal processor for converting said one input frame to an output frame to a display device; wherein the control device replaces said one input frame in the frame buffer with the output frame and directly outputs the output frame to the display device bypassing the image signal processor after the output frame is stored in the frame buffer. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
