<p>PURPOSE: To make block distortion inconspicuous when a screen is freezed at the time of a special reproduction, in particular, by outputting a reproduced image by performing the post filter by a screen unit after only partial fields or frames are read and decoded at the time of the special reproduction. CONSTITUTION: The image information recorded on a recording media 1 is read by an information detection circuit 2, a digital demodulation, etc., is performed for the information and the information is outputted to an error correction circuit 3. The separated motion vector information is inputted in a predicted data decoding circuit 7, and image information is inputted in a variable length decoding circuit 5 and is outputted to a memory circuit 9 via an IDCT circuit 6 and an adder 8. A selection circuit 11 selects the image information to be outputted by synchronizing with a frame signal from the memory circuit 9 and outputs the information to an output terminal 12 at the time of a normal reproduction. At the time of a high speed reproduction, the image information that a filter processing is performed for the output of the memory circuit 9 by a post filter circuit 10 is selected and is outputted from an output terminal 12.</p> |
