PURPOSE:To perform a desired processing for a picture, by dividing the center picture element out of three continuous picture elements into two by a read instructing equipment to process density information and by outputting repeatedly a signal based on the sum of picture element densities in both ends and the center density. CONSTITUTION:Input signal Si becomes a digital signal by quantizer 40; and when required information is stored in memory 41, read instructing equipment 42 opens the gate of the stage or the address corresponding to picture elements B, E and H and distributes the output signal to operator 44 and adder 43. This distribution is performed by transmitting input signals corresponding to picture elements B, E and H to the adder 43 side and the operator 44 side by the first and the second clocks and the second clock respectively. After that, operator 44 starts operating after input signals QB and +QB+QB+QH are obtained, and signals Q1 and Q2 are output to output buffer 45. This operation is repeated at the prescribed timing to achieve desired processing for the picture. |
