Abstract: PURPOSE:To accurately count particles within a short time. CONSTITUTION:Two data are obtained from a specimen containing two or more kinds of blood corpuscles in a mixed state at every blood corpuscles to obtain distribution diagram data. Fixed regions are set to the distribution diagram data at every kinds (S2). This setting is performed so that blood corpuscles of the kinds to the fixed regions are necessarily distributed on the fixed regions. The attribution degrees to the clusters of the blood corpuscles of the fixed regions are set to 1. Initial center-of- gravity positions are obtained at every clusters from the blood corpuscle distribution within the clusters (S4). The attribution degrees to the respective clusters are obtained from the distances to the initial center-of-gravity positions of blood corpuscles outside the fixed regions (S6). The weighting center of gravity is obtained from the attribution degrees to the respective clusters of blood corpuscles (S8). It is judged whether the differences between the initial center-of-gravity positions and the weighting center-of- gravity positions are a predetermined amount (S10) and, in the case of NO, the processes S6-S10 are repeated using the weighting center-of-gravity positions until the predetermined amount is obtained. In the case of YES, the numbers of blood corpuscles belonging to the respective clusters are calculated from the attribution degrees to the clusters of respective blood corpuscles at that time.
