1. A particle image analysis method for picking up still images of particles as the particles flowing in a flow cell are detected and analyzing the picked-up still images of the particles, comprising the steps of:

  • a) flowing fluid having particles suspended therein to the flow cell;

    b) counting the number of still images of particles having larger sizes than a predetermined size, of the still images of particles obtained for the fluid;

    c) counting the number of particles having larger detection signals than a predetermined level, of the particles detected for the fluid;

    d) calculating the anticipated number of particles to be image-processed based on the counted number of particles; and

    e) comparing the counted number of still images and the calculated number of particles.
