<p>PURPOSE:To offer a still picture without any blurring to an original that includes a moving image by detecting whether an original video signal is a still image signal or a moving image signal, and executing a still display with video signals obtained by applying moving image processing only to the moving image signals. CONSTITUTION:When a change-over switch 13 is switched to a still mode-side (b) and the video signals stored in memories M1-M4 are still image signals, the three bits of moving image information corresponding to 4-field-length of video signals are all '000', therefore, the output of a moving information processing circuit 8 goes to '000', and a mixing circuit 10 outputs only output signals from an inter-frame interpolation circuit 4. When the video signals in the M1-M4 are moving image signals, the three bits of moving information corresponding to them go to '001'-'111', and a processing circuit 8 outputs the moving information in the maximum value. The mixer circuit 100 mixes the output signal of the circuit 4 generated from the 4-field- length of video signals and video signal for still the output signals of an in-frame interpolation circuit 6 at a mixing proportion in accordance with the moving information, and generates video signal for still image.</p> |
