<P>PROBLEM TO BE SOLVED: To provide an image processing system that performs image processing without generation of an unnatural interpolation frame signal when an OSD signal is displayed in a case in which an interpolation frame signal is generated based only on an input video signal in a frame generation circuit, regardless of the OSD signal. <P>SOLUTION: A frame generation circuit 52 generates an interpolation frame signal of an input video signal 51 with a known configuration. A selector 53 generates a signal having a frame frequency of 120 Hz by sequentially selecting the interpolation frame signal generated in the frame generation circuit 52, and the input video signal 51 within one frame period. A synthesis circuit 54 synthesizes the output signal of the selector 53 and an OSD signal output from an OSD signal generator 55, and outputs the synthesized signal as an output signal 56. <P>COPYRIGHT: (C)2013,JPO&INPIT |
