Abstract

Many improvements for a high speed camera including being able to process image data from a CCD array at one-quarter the pixel rate at which that image is provided by the CCD array; automatically demultiplexing color information in the digital domain; a high frequency, temperature compensated phase shift clock circuit to individually adjust the phase of the clock signal to each A/D converter; high frequency, high power analog, bipolar clock drivers to drive the horizontal functions of the CCD array since the necessary speed and power is not available in the horizontal driver section of commercially available CCD drivers; a technique to minimize the smearing of partial values of previous pixels into later pixels since the CCD array is being clocked faster than the internal time constant of the output stage of the CCD array; determination of, and compensation for, the dark reference (i.e., black level) offset of the pixel data streams from the CCD array; and subtracting the dark reference offset from the data pixel signal stream from the CCD array to stabilize the operating point of the output amplifier following the CCD array.
