ABSTRACT:
An apparatus for discriminating a particle aggregation pattern includes a memory circuit for storing line data output from a CCD line sensor, which line data represents the aggregation pattern. A maximum value is obtained for each set of line data, and thereafter a further maximum value is obtained from the afore-mentioned previously obtained maximum values. A threshold value is determined on the basis of the further maximum value, and is then applied to the line data in order to extract therefrom information regarding the shape and area of the aggregation pattern. In another embodiment, the threshold value is determined on the basis of minimum values obtained from the line data.
