Patent ID: 8538119

Claim:
A particle image analyzing method, comprising: detecting particles flowing through a flow cell; determining from a particle detection signal obtained whether desired particles are to be imaged, and then acquiring images of the desired particles; storing an acquired overall image of a sample into an overall-image memory; extracting particle components contained in the sample, and the number of the particles, from the acquired overall image of the sample; analyzing the extracted particle components in accordance with feature parameters, then after classifying the particle components according to the kind of component, computing respective concentrations of the classified components, and storing the classified components with the computed concentrations into a cropped image memory; displaying on display means the overall image stored in the overall-image memory; and in accordance with to-be-added or to-be-changed particle component information entered from operating means, conducting modifications and concentration-modifying computations upon the components stored in the cropped image memory.
