Abstract: In various embodiments, a time-delay-and-integrate (TDI) image sensor includes (i) a plurality of integrating CCDs (ICCDs), arranged in parallel, that accumulate photocharge in response to exposure to light, (ii) electrically coupled to the plurality of ICCDs, a readout CCD (RCCD) for receiving photocharge from the plurality of ICCDs, and (iii) electrically coupled to the RCCD, readout circuitry for converting charge received from the RCCD into voltage.

Abstract: There is disclosed a thermal printer system in which variations in voltage (and the energy corresponding thereto) supplied to resistance elements of a print head are electronically compensated for. The voltage at the print head is monitored as a line of pixels is being printed pixel by pixel. Units of energy (corresponding to the measured voltage) which have been supplied to the resistance elements are counted, the counts are added together pixel by pixel to obtain cumulative totals and the cumulative totals converted into "compensating" numbers. An image data number for each pixel is compared to the corresponding compensating number, and a respective resistance element is pulsed (energized) a requisite number of times until the image data and compensating numbers match thus achieving a desired level of print density corresponding to the respective image data number.

Abstract: In a digital image scanning system, dynamic testing of digital and analog channels is performed by injecting photosite-by-photosite variable test data to simulate imager signals. The test data is stored at photosite related addresses in random access memory means and are accessed by a pixel (photosite) counter for output to the channels under test.
