ABSTRACT:
A particle image analyzer includes a first light source for applying strobe light to a sample solution flowing through a flow cell, first image pick-up means for taking a still picture of a particle in the sample solution irradiated by the first light source, a second light source for constantly irradiating the sample solution in the flow cell, and second image pick-up means for picking up an image of the sample solution in the flow cell irradiated by the second light source. When a particle is detected from the image pick-up data from the second image pick-up means, the first light source is flashed, based upon detection of the particle, in a predetermined image pick-up interval of the first image pick-up means.
