Abstract

PURPOSE: To perform stable quantization, by providing maximum value and minimum value detecting circuits for signals and by using the signal of only the minimum value detecting circuit for quantization if the input signal is a fixed value or less and by using signal of both circuits for quantization if the input signal is the fixed value or more.
CONSTITUTION: Signals from the sensor are amplified by n-number sets of preamplifiers 21. The minimum value detecting circuit consisting of diode 23 and the maximum value detecting circuit consisting of diode 27 are connected to voltage source 36 of EV in the output side of the these amplifiers. Outputs of the these circuits are given to comparing circuit 34 through division resistances R2 and R3. In this constitution, the maximum value detecting circuit is not operated unless the maximum value exceeds the voltage of voltage source 36. Consequently, signals from a strong-contrast signal to a weak-contrast signal is quantized stably.
