ABSTRACT:
A motion area detector capable of simple detection of a moving picture-area in a HDTV receiver of a multiple subsampling transmission system is disclosed. The motion area detector includes a still-picture processor for reproducing a still picture from a picture signal applied into the detection circuit of the receiver, a moving-picture processor for reproducing a moving picture from the picture signal, a mixer for carrying out a linear mixing operation between the still picture and the moving picture, and a motion detector for detecting a motion area from a mixed picture signal of the mixer and from the still picture signal reproduced by the still picture processor and for providing information concerning a mixing ratio between the still picture and the moving picture.
