发明名称 Apparatus for recording and/or reproducing a video signal
摘要 An apparatus for recording and/or reproducing a video signal as a moving image or a still image. A moving image may be recorded in a first (YCrCb) recording mode wherein a luminance signal Y and color difference signals (R-Y) and (R-B) corresponding thereto are recorded. A still image may be recorded in a second (RGB) recording mode wherein three primary color signals corresponding thereto are recorded. In the RGB recording mode, the amount of information of each of the three primary color signals may be set to at least the amount of information of the luminance signal Y of the YCrCb recording mode such that, upon the reproduction thereof, a reproduced still image having a relatively high resolution is obtained.
