摘要：Image enhancement is automatically achieved by calibrating the referencevoltage and gain of a differential amplifier and the integration interval so as to provide an

input to a differential analog to digital converter (ADC) that utilizes the full dynamicrange of the ADC. When used with a CMOS array, the imaging logic can be fabricated on asingle chip with the array using combinational logic for fast, inexpensive calibration.Another advantageous feature is the ability to expand a desired portion of the luminancespectrum of the image in order to increase the digital resolution of the resulting imagefor that portion of the spectrum of interest.
