Abstract

Abstract A particle image analyzer that facilitates display by designating on a distribution an image desired to be displayed from among a large number of recorded images is disclosed. The particle image analyzer is provided with a parameter computation means for computing at least one characterizing parameter for respective particle images obtained by image capture; a storing means for storing correlations between the particle images and the characterizing parameters with regard to the respective particle images; distribution-diagram generation means for generating characteristic-parameter distribution diagram; designation means for designating the area within the distribution diagram; read-out means for reading out from the memory means particle images corresponding to characterizing parameters within the areas designated by the designation means; and display means for displaying the read-out particle images.
