This cell is provided with a time input port a<t>, a plurality of space input ports b0 to bu, a time output port a<t+1>, a plurality of space output ports C0 to Cu and a calculation circuit to obtain the time output data and space output data from the time input data and space input data. The cell is so structured that the time output data is inputted into the time input port as the next time input data. The calculation circuit uses the above-mentioned time input data as time output data after inverting it or as it is, without inversion, depending on whether or not the sum of all the space input data is larger than a threshold value, and uses all the space input data as space output data after inverting it or as it is without inversion in accordance with the logic of the time input data. A plurality of basic cells are arranged in matrix in correspondence with the pixels arranged in matrix. The space output port and space input port of each basic cell are connected to the space input port and space output port of the other basic cells, respectively, to form a spatio-temporal pulse generator. <IMAGE> |
