  • Optical adaptive thresholder for converting analog signals to binary signals
    Patent number: 5617489
    Abstract: An adaptive threshold for converting an analog video signal to a binary video signal. This video system employs two identical array sensors. These sensors are operated synchronously and each has its own lens. The lens of the primary array sensor is focused for a sharp image. The analog output of this primary array sensor is the primary video signal. A secondary array sensor is implemented with its lens intentionally set to some degree of defocus. This degree of defocus defines the adaptive threshold function, independent of the primary video. The analog output of this secondary array sensor is the adaptive threshold signal.
