    • In an apparatus for detecting movement of a television image in response to frame difference data corresponding to a difference between present frame data and previous frame data, a video signal is divided into a plurality of segmental areas for each frame, a pixel or picture element is selected to represent each of the segmental areas, frame difference data are produced for each of the segmental areas by calculating differences in the position or coordinates of a pixel representative of a segmental area of a previous frame from the respective picture element of the corresponding segmental area in the present frame, and each of the calculated differences smaller than a predetermined magnitude, and which would be characteristic of a stationary background portion of the television image, is omitted from the frame difference data. This is effective to improve the movement vector detection accuracy. The apparatus has a circuit for zeroing the frame difference data, and thereby improving, the movement vector detection reliability when the number of the calculated differences omitted from the frame difference data exceeds a predetermined value.

    • The present invention provides an apparatus which receives and displays a high definition television signal and which is constructed so that noise and/or a deformed picture may not be displayed even when an input signal instead of a high definition television signal is applied or when transmission of such a high definition television signal is interrupted. In the apparatus, on the basis of whether or not a frame signal in an input high definition television signal can be detected, a first signal indicating synchronization lock or a second signal indicating synchronization unlock is generated so that, when the first signal is detected, the output of a signal processing circuit (110) is selected to display the high definition television signal, while when the second signal is detected, the output of a pattern generation circuit (114) is selected to prevent display of noise etc.
