Abstract

PURPOSE:To effectively execute an extraction processing of a feature and to reduce the capacity of a dictionary for storing the information of a feature, by selecting an effective combination of a feature which has been selected objectively, and a field of view of an observation window which has been made to correspond to said feature. CONSTITUTION:To operating circuit parts 1-6 for extracting a feature to a field of view is inputted a pattern information having size of a field of view of an observation window, respectively, a feature corresponding to a field of view of N1XN1 meshes is extracted by the circuits 1, 3 and 5, and a feature corresponding to a field of view of N2XN2 meshes is extracted by the circuit parts 2, 4 and 6. Features which have been extracted to the first-n-th recognition object graphic forms by these circuit parts 1-6 are inputted to the respective corresponding operation processing parts 7-12 for deriving a stable coefficient. After that, in the processing parts 7-12 is executed an operation for deriving a stable coefficient in case of combining the size of a field of view and a feature, a stable coefficient value which has been derived in the processing part 7-12 is inputted to a comparing circuit 13, a calculated value of a stable coefficient is compared, and combination of a feature of a recognition object graphic form corresponding to its minimum value, and size of the field of view is decided.
