Abstract
A picture reproducing device in which a still picture can be recorded/reproduced to high picture quality without requiring a dedicated still picture processor or a RAM configured for storing picture data for processing by the dedicated still picture processor. Input video signals are all processed with DCT in a DCT/IDCT processor 4 as a continuous frame picture from one transform block to another and quantized by the quantizer/dequantizer 5 so as to be then recorded on a recording medium. Reproduced signals from the recording medium are dequantized by the quantizer/dequantizer 5 to give coefficient data which are processed with inverse DCT by the DCT/IDCT processor 4 to generate playback video signals. Responsive to the coefficient data based results of motion detection effectuated from one transform block to another, the playback video signals are outputted as playback video signals from the blocking shuffling/deblocking deshuffling processor 2. At this time, still picture blocks are outputted as a frame, while moving picture blocks are outputted as twice-outputted single-fields.
