ABSTRACT:
An automatic cyto-screening device calculates, from image signals obtained by scanning stained cells, the nuclear area of the cells and the nuclear area/cytoplasmic area ratio, and determines, from the calculated areas, which belong to a normal region, which belong to an abnormal region and an uncertain region in which normal and abnormal cells are present in the mixed state; these three regions are prescribed in advance, depending on the nuclear and cytoplasmic areas. The device also determines, according to the grey histogram of the nuclear density, whether cells which have been determined to belong to the uncertain region are normal or abnormal.
