1. A flow imaging cytometer comprising:

  • a flow cell formed to include a flat flow path for causing a specimen solution containing particle components to be sensed to flow as a flat stream;

    a first light source arranged on a first side of said flow cell for irradiating the specimen solution in said flow cell with light the quantity of which is switched;

    first image capturing means arranged on a second side of said flow cell for capturing still pictures of particle components in the specimen solution irradiated with high-luminance pulsed light from said first light source;

    second image capturing means arranged on a second side of said flow cell for capturing images of the particle components in the specimen solution irradiated continuously with low-luminance light from said first light source;

    processing means for executing prescribed analysis based upon image data from said first and second image capturing means; and

    control means for detecting the particle components based upon the image data from said second image capturing means, and on the basis of such detection, switching said first light source over to irradiation with the high-luminance light, wherein the particle components to be sensed are treated with a fluorescent stain and said first light source is for exciting fluorescence.
