Abstract

PURPOSE:To facilitate an easy deformation for the complicated picture in real time and with a high speed by carrying out the arithmetic process in which the deviation amount of each picture element before and after the process is expressed in the form of the parameter. CONSTITUTION:The optical picture information sent to image sensor 1 is sent to A/D converter 10 via delay circuit 2 to be digitized into digital picture information Fij or the like in the unit of picture element. And the contents of the digitization is memorized temporarily into register 11. At the same time, the deformation command to set properly each deformation amount of the picture manually is given from outside. Thus divider circuit 12 which performs the operation based on the deformation command is provided along with adder circuits 13 and 14 which perform the operation according to the result of the division plus adder circuits 15 and 16 which carry out the operation according to the output of circuits 13 and 14 each. In such constitution, the digital coordinates of the picture element are obtained by the operation and by expressing the deviation amount before and after the process in the form of the parameter. And the operation is given among the result of the operation, the contents memorized previously and the input digital picture information each. Thus the concentration signal is obtained at the picture element position after conversion.
