Abstract
A first digital processor (13) generates luminance data Y and color difference data U, V, using image data D1. The processor (13) further generates separated luminance data Y1, Y2 by halving the luminance data Y, and generates a compound color difference data C by combining the color difference data U, V for output. An JPEG encoder 13 compresses the separated luminance data Y1, Y2 and the compound color difference data C to generate compressed luminance data y1, y2 and compressed color difference data c. A modulator 15 modulates the compressed luminance data y1, y2 and the compressed color difference data c to generate luminance modulated signals m1, m2 and color difference modulated signal mc. A recording/reproducing section 16 records the luminance modulated signals m1, m2 and the color difference modulated signal mc in parallel onto the first to third recording tracks of a magnetic tape (20).
