Abstract

PURPOSE:To increase precision and reliability in leukocyte detection, by having the detection level follow the leukocyte absorption level in the video signal. CONSTITUTION:By scanning blood specimen 3 obtained by optical system 1, analog signal a is output by 5. This is delayed by 10, and of video signals b, only one of a fixed, limited period in each scanning period is passed by 11. This output signal e is level-shifted by 14, and thereby detection level f is determined; and the signal which has passed LPF 15 is voltage-divided by 16 and 17. This voltage-divided output g is used as the discrimination level of video signal a. When output i is obtained from comparator circuit 8, FF12 is set, sample hold circuit 11 is maintained, and output i is taken out as the leukocyte detection signal.
