Abstract:
Apparatus for providing electrical signals that represent an optical image to a processor for conversion to video signals that represent said optical image and which are suitable for display on a display device, said apparatus comprising,a device operable to be inserted into a region to be viewed for developing an optical image of said region,an imager supported by said device and operable to generate electrical signals that represent said optical image,a digital memory supported by said device and storing information about said imager for use by the processor in converting the electrical signals produced by said imager to said video signals that represent said optical image, said information including information identifying variations in performance characteristics of said imager relative to nominal performance characteristics, andsaid device being adapted for connection to the processor so that the processor can receive said electrical signals from said imager and obtain said information from said digital memory for use in converting the electrical signals from said imager to said video signals that represent said optical image, wherein said received electrical signals are distinct from said information from said digital memory.
