PURPOSE:To perform a high speed processing at relatively low cost by once transferring the picture data from a picture data memory device to a work memory and carrying out a picture processing by the use of the picture data. CONSTITUTION:When performing a vector convolution integral of 0 deg. direction is performed on the picture data in a dynamic RAM41a, the 256 picture data of j=0 line is simultaneously read in a serial input and output circuit 41b. The first picture data D0,0 is shifted and loaded to a register 10c, further, the data D0,1 is similarly loaded to the register 10c. At this time, the contents (D0,0) of the register 10c is shifted to a register 10b. In a processor 10, considering the data D0=0, D1=D0,0, D2=D0,1 in the registers 10a-10c, G0=omega0D0+omega1D1+omega2D2 is calculated, the calculation result G0 is preserved in a resister in which the picture data of the serial input and output circuit 41b is stored. Similarly, the picture processed in a whole of one line and when the calculation result is obtained, it is stored in the dynamic RAM41a. |
