Patent ID: 8339441

Claim:
A frame processing device, comprising: a first frame extraction module configured to extract a first image frame from a first video signal and a second image frame from a second video signal from a three-dimensional video signal containing the first and the second video signals; a second frame extraction module configured to sequentially extract a plurality of third image frames from a two-dimensional video signal containing the third image frames; a frame storage module configured to store the first, the second, and the third image frames extracted by the first and the second frame extraction modules; an inserting module configured to generate an interpolation frame from successive third image frames stored in the frame storage module and insert the interpolation frame between the successive third image frames to increase a display output frame frequency; a display rewrite module configured to sequentially rewrite a display on a display screen with the extracted image frames by either: (1) alternating between a first procedure of rewriting the display with the first image frame stored in the frame storage module a plural number of times to increase the display output frame frequency, and a second procedure of rewriting the display with the second image frame stored in the frame storage module the plural number of times to increase the display output frame frequency, or (2) rewriting the display on the display screen with the third image frames and the interpolation frame; and a display module configured to invalidate the display on the display screen during a first rewriting period in which the display rewrite module rewrites one of the first image frame and the second image frame with a different one of the first image frame and the second image frame, and configured to not invalidate the display on the display screen during a second rewriting period in which the display rewrite module rewrites one of the first image frame and the second image frame with the same one of the first image frame and the second image frame.
