<P>PROBLEM TO BE SOLVED: To provide a particle image analyzer capable of analyzing particle images imaged using dark-field illumination to acquire morphological characteristic information, while simplifying imaging processes of transparent particles. <P>SOLUTION: The particle image analyzer includes an illuminating optical system 4 for implementing dark-field illumination to particles, an imaging optical system 5 for imaging particles dark-field-illuminated, an image processing substrate 6 extracting particle image from taken images by dark-field illumination to derive morphological characteristic information representing morphological characteristics of particles by analyzing the extracted particle images and an imagery data processing section 2b. The image processing substrate 6 and the imagery data processing section 2b are comprised to extract particle images from imaged imageries, based on a larger threshold value than brightness corresponding substantially to background of particle images. <P>COPYRIGHT: (C)2008,JPO&INPIT |
