Abstract:
A projection display apparatus includes a processing circuit and an image projection display device. The processing circuit is configured to perform a dynamic motion compensation based on two successive first frame and second frame in a first video signal, in order to generate a complement frame between the first frame and the second frame. The processing circuit is further configured to combine the first frame and the complement frame into a third frame, and to decompose the third frame to generate a plurality of fourth frames and to output the fourth frames as a second video signal. A resolution of the first video signal is higher than a resolution of the second video signal. The image projection display device is configured to project and display the second video signal, in which the imaging device has an original resolution equal to the resolution of the second video signal.
