Particle image analyzing apparatus

Abstract

A particle image analyzing apparatus of high classifying accuracy and high efficiency in which a criterion for determining whether fine classification is required or not can be set for every facility such as hospital, or the like. A rough classification unit executes rough classification of particles and supplies results of the rough classification to a fine classification necessity determination unit. The necessity determination unit compares the results of the rough classification with reference values stored in a reference value storage unit and determines from the comparison whether every sample is normal or abnormal to thereby determine whether fine classification is required or not. The reference values stored in the storage unit can be changed in accordance with the subject of examination through an input/output control unit from a keyboard. When the determination unit makes a decision that fine classification is required, the determination unit gives an instruction to an image processing control circuit to execute fine classification. Characteristic parameters for fine classification are supplied to a fine classification unit on the basis of the control instruction of the control circuit. Then, fine classification is executed, so that results of the fine classification are supplied to the determination unit.
