Abstract:
A picture recording/reproducing apparatus comprising:a recording system for orthogoanl-transforming input video signals in terms of a transform block as a unit, said transform block having a pre-set number of two-dimensionally arrayed pixels, with all video input signals as a continuous frame picture, said recording system quantizing orthogonal-transformed coefficient data and recording the quantized coefficient data on a recording medium; anda reproducing system for inverse orthogonal-transforming the orthogonal-tranformed coefficient data obtained by dequantizing playback signals reproduced from the recording medium, for generating playback video signals, effectuating motion detection from one transform block to another transform block, based on the orthogonal-tranformed coefficient data, said reproducing system outputting playback video signals of a transform block, detected as being a still picture block, as a frame, said reproducing system also outputting playback video signals of a transform block, detected as being a moving picture block, as a twice-outputted single-field.
