ABSTRACT:
A signal processing apparatus includes an updown counter for storing a maximum value of analog video signals produced from an array of photoelectric converting elements in a form of digital signal, and a distortion memory for storing a distortion characteristic of the analog video signal output from the photoelectric converting element. A reference voltage is produced on the basis of the output voltages from the up-down counter and the distortion memory to be compared with the analog video signal output from the photoelectric converting element array for encoding the analog video signal into a corresponding binary signal. The up-down counter is decremented with a periodical interval.
