Abstract
An image processing method for a video processor to generate an interpolated frame includes steps of: receiving a touch information from a host processor or a display driver circuit; finding at least one motion vector (MV) by performing motion estimation according to the touch information; and constructing the interpolated frame by using the at least one MV.
Claims21
An image processing method for a video processor to generate an interpolated frame, the image processing method comprising:
- receiving a touch information;
- finding at least one motion vector (MV) according to the touch information;
- and
- constructing the interpolated frame by using the at least one MV;
- wherein the touch information comprises a moving direction of a touch gesture, and the step of finding the at least one MV according to the touch information comprises:
- searching a plurality of candidate MVs only in a region corresponding to the moving direction of the touch gesture;
- and
- selecting a second MV among the at least one MV from the plurality of candidate MVs.
(canceled)
A video processor to generate an interpolated frame, the video processor comprising:
- a motion estimation (ME) circuit to receive a touch information and find at least one motion vector (MV) according to the touch information;
- and
- a motion compensation (MC) circuit to construct the interpolated frame by using the at least one MV;
- wherein the touch information comprises a moving direction of a touch gesture, and the ME circuit searches a plurality of candidate MVs only in a region corresponding to the moving direction of the touch gesture, and selects a second MV among the at least one MV from the plurality of candidate MVs.
(canceled)
A display system comprising:
- a host processor to generate a previous frame and a current frame;
- a video processor, coupled to the host processor, to generate an interpolated frame according to the previous frame and the current frame, the video processor comprising:
- a motion estimation (ME) circuit to receive a touch information and find at least one motion vector (MV) according to the touch information;
- and
- a motion compensation (MC) circuit to construct the interpolated frame by using the at least one MV;
- and
- a display driver circuit, coupled to the video processor, to drive a display panel to display the interpolated frame;
- wherein the touch information comprises a moving direction of a touch gesture, and the ME circuit searches a plurality of candidate MVs only in a region corresponding to the moving direction of the touch gesture, and selects a second MV among the at least one MV from the plurality of candidate MVs.
