The apparatus comprises an illuminating system including a rotary filter for spectrum-analyzing a sample containing white blood corpuscles subjected to WRIGHT staining process, for example, and mounted on a glass slide, into monochromatic lights having different wavelengths in the visible light range, a video camera for scanning a predetermined area of the spectrum-analyzed sample for producing a picture image, a photoelectric transducer for producing an electric signal corresponding to the tone of the picture image at the sampling point in the predetermined area, a digital-analogue converter for converting the electric signal into a digital signal, a memory device for storing the output from the digital-analogue converter, a circuit for normalizing the information stored in the memory device, similarity calculating circuit for determining the similarity between the output from the normalyzing circuit and reference data, means for detecting and storing the types of the white blood corpuscles respectively corresponding to the maximum value and the value next to the maximum of the similarity thus determined, means for classifying the sampling points of each type of the white blood corpuscles and counting the number of the sampling points, and means for estimating the number of the white blood corpuscles of each type in the predetermined area based on the nunber of the sampling points. |
