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.

Abstract: A projection device includes multiple optical fiber mounting mechanisms. Each of the optical fiber mounting mechanisms includes an optical fiber extending along a first direction as an axis direction, a signal circuit extending along the first direction, and a mounting structure. The optical fiber includes an engaging section. The mounting structure surrounds the engaging section of the optical fiber and the signal circuit. The mounting structure includes an installation portion extending radially relative to the first direction. The installation portion includes a surface and multiple elements exposed from the surface. The surface includes a normal direction parallel with the first direction. A first length of the engaging section of the optical fiber protruding from the surface of the installation portion is longer than lengths of the elements protruding from the surface.
