Abstract

PURPOSE: To obtain a precisely binary-coded complex picture including two or more kinds of formats by obtaining the best threshold levels for two or more kinds of binary-coding formats in respective threshold level generating circuit and by composing individual binary-codes signal as to every format.
CONSTITUTION: When two or more kinds of formats, e.g. light and shade pictures of positive and negative lymph cells to be been black disk A and black ring B in a phase-difference microscope are binary-coded, threshold level generating circuit 91 for positive lymph cell detection obtains a circumferential density average TP as a threshold value by substracting a diameter range D(-3)WD(3) of lumph cells from a picture information D(-7)WD(7) obtained by an one-dimensional image sensor 100. Negative threshold level generating circuit 92 obtain as a threshold level mean density TN within the diameter range of lumph cells centering on picture element "0" as shown in the figure. Then, binary coding circuit 93 outputs [1] when TP>D(0) or TN>D(0) or [0] when not. Consequently, a complex picture including two or more kinds of formats is binary-coded accurately.
