PURPOSE:To simplify a description and to improve its efficiency by incorporating a mechanism which takes a measurement in an interpretation and execution part for the description of classifying algorithm unless the measurement is taken when an image feature quantity is referred under the execution of the classifying algorithm and then describing only the decision logic of the image feature quantity. CONSTITUTION:A pattern classifying algorithm description memory 3 is stored with the description of only the decision logic except the description of image feature quantity measurement processing. An interpreter 32 reads its contents out successively and performs the decision processing, but the image feature quantity used for the decision making is referred to through an image feature quantity reference processing part 33. The processing part 33 refers to a feature quantity structure table in a feature quantity memory 34 as to a feature quantity specified by the interpreter 32 and when the value is already set, the value is returned to the interpreter 32; when not, a measurement and a calculation procedure are selected in a feature quantity measurement and calculation processing part 35 and started, thereby returning a value which is set as a result to the interpreter 32. Consequently, the description of the pattern classifying algorithm is simplified.
