ABSTRACT:
An apparatus for converting a wide screen television signal to a desired normal screen television signal includes an extraction circuit for selectively extracting a portion of the wide screen television signal corresponding to a normal screen television picture to obtain the desired normal television signal, a motion detector for detecting a motion of a picture produced by the wide screen television signal, and a control circuit for controlling the extracting circuit to extract the portion of the wide screen television signal according to a motion detection result of the motion detector. A plurality of candidate areas to be extracted from the wide screen television picture are predetermined. The motion detector detects from among the plurality areas an area in which the motion of the picture is the largest. The control circuit controls the extracting circuit to extract a portion of the wide screen television signal corresponding to the area in which the motion of the picture is the largest.
