PURPOSE:To shorten an inspecting time by providing an image processing device which receives the output of an image sensing device and outputs only the image that is present in a luminance level which can be set arbitrarily, and providing a particle counter for counting the number of the images. CONSTITUTION:The mercury light emitted from a mercury lamp 1 is projected on a sample 7 through a collector lens 2, an exciting filter 3, a mirror 4 and an objective lens 5. At this time, the light in the specified wavelength region which is selected with the filter 3 is projected on the sample 7 and excites a fluorescent coloring matter. Of the excited light, the light in the specified wavelength region in cut in an absorbing filter 8 through the lens 5. The light is captured with a camera 10 through an eyepiece lens 9. Only an image in a luminance level which can be set arbitrarily is outputted. The image is processed in an image processing device 11. The image is displayed on a monitor 12. When the numbers of cells whose amounts of light emission are different are individually counted, the signal obtained by the image processing in the device 11 is linked to a particle counter 13. Thus the numbers of the cells corresponding to the intensities of the light can be read out. |
