Abstract

PURPOSE:To ensure automatic synthesis of pictures through a machine, by calculating the center line of a picture picked up with a center line calculating means and thus synthesizing the pictures by making the center lines of pictures coincide. CONSTITUTION:The head of a figure picture picked up by a TV camera 10 plus a soft picture are stored in a picture memory 2, and this picture signal is sampled to be supplied to a picture synthesizing device 12 as a digital signal and after an A/D conversion. The picture signal supplied to the device 12 is supplied to a masking circuit 20, and only the necessary region is wiped by the control signal SG of a synthesis control circuit 24. Then the output signal MI is applied to a mean value calculating circuit 21 to calculate a center line in the horizontal direction. Two pictures are switched by an input switching circuit 22 and delivered to a picture memory 23, and the signal sent from a magnetic disk 13 is applied to the memory 23 in terms of the lower part of the picture. Thus a coincidence is secured automatically for the each center line between the pictures based on the information given from the circuit 21 concerning the center line is made to coincide. In such way, the pictures are synthesized mechanically.
