Classification and examination device of particles in fluid.

摘要

A particle image in a sample 63 is formed at an imaging position 56 by an objective lens 55 of a microscope, projected on the image picking up plane of a TV camera 58 via projection lens 57 and is subjected to photo-electric conversion. Image signals from the TV camera 58 are supplied to an image memory 75 via an A/D converter 74 as well as to an image processing control unit 76. Image signals outputted from the image memory 75 are supplied to a characteristic picking out unit 78 and there a plurality of characteristics of the particle concerned are picked out. The picked-out characterstics are supplied to the classification unit 79 and there classification of the sediment components is performed via a neural network with a learning capability. Accordingly, the classification unit 79 performs provisionally an automatic classification of the objective sediment components by making use of the inputted characteristic parameters. Whereby the device which allows accurate and fast automatic component particle analysis even for patient specimens containing a variety of components in high concentration is realized.
