IMAGE MEASURING DEVICE AND IMAGE MEASURING METHOD

摘要

An image measurement apparatus (1000) includes: a lighting unit (101) that emits a first narrowband light with a bandwidth (i) narrower than a bandwidth of a visible light and (ii) including a dominant wavelength of a color of a positive cell nucleus; an image obtaining unit (102) that obtains an examination image by capturing an image of a pathologic examination specimen (108) to which the first narrowband light is emitted; a cell nuclei extracting unit (103) that extracts pixels of positive cell nuclei from the examination image by comparing pixel values of the examination image with a predetermined threshold; a positive proportion calculating unit (105) that calculates a proportion of the positive cell nuclei among cell nuclei included in the pathologic examination specimen, using the pixels of the positive cell nuclei extracted by the cell nuclei extracting unit; and an output unit (114) that outputs the proportion.
