A spatio-temporal pulse firing basic cell has a time input port at, a plurality of space input ports b0-bu, a time output port at+1, a plurality of space output ports c0-cu and a calculating circuit for obtaining time output data and space output data from time input data and space input data, and the basic cell is configured so that time output data is provided as the next time input data to the time input port. The calculating circuit inverts the time input data or holds it uninverted, depending upon whether the added value of the whole space input data is larger or smaller than a predetermined threshold value, and provides it as the time output data, and at the same time, the calculating circuit inverts the whole space input data or holds it uninverted, in accordance with the logic of the time input data, and provides it as the space output data. A plurality of basic cells are arranged in a matrix form corresponding to matrix-arranged pixels and space output ports and space input ports of each basic cell are connected to space input ports and space output ports of a plurality of other basic cells, respectively, to form a spatio-temporal pulse generator.
