Abstract

PURPOSE: To realize reduction of the memory capacity for detection of the motion picture and thus to secure the treatment even with a large shift distance of the motion pricture.
CONSTITUTION: The digital-coded input TV signal 21 is applied to 1-field memory 22 to be then delivered with time delay of one field. Then the space position signal which is lower by half of the vertical space of the horizontal scan line is produced through the interpolation in the form of output 29 via the vertical position interpolation circuit consisting of delay line capacity memory 26 and interpolation unit 27. While no alteration occurs for the space position within the vertical position interpolation circuit. When a reversion is given to the field relation between signal 21 of the input side and signal 25 of the output side in memory 22, the opposite operation to that mentioned above is carried out. Thus the identity is secured for the space position between output signals 29 and 30. These signals are used to obtain the difference through motion picture detection circuit 28, thus enabling the decision for the motion picture image.
