An apparatus for searching data on the basis of feature pattern comprises a plurality of processors of which at least one is activated in response to the results of the processings performed by the other processors which operate independent of one another for recognizing individual feature patterns of input pattern data, respectively, devices for outputting the results of the processings performed by the other processors to the one processor, controller for controlling the activation of the one processor on the basis of the outputted results of the processings, and a large-capacity file arranged to use data constituted by arrays of the results of recognitions outputted from the plural processors directly as the addresses. | |
