Readout of pixel data from array of CCD image detectors

摘要

In systems for reading pixel data from an array of horizontal m-bit rows of CCD image detectors, pixel data loaded in parallel from a row of the array into an m-bit shift register is transferred in parallel from the m-bit shift register into other data storage device(s) having a plurality of output ports and sensed by a plurality of output amplifiers respectively connected in parallel to the output ports of the other data storage device(s). In a parallel-output-serial-register system in which the m-bit serial shift register has n cells at one end of the m-bit shift register that respectively have n output ports and an output register having n cells respectively connected in parallel to the n output ports of the m-bit shift register, with a plurality of different cells of the output register respectively having output ports, the loaded pixel data is shifted through the shift register toward the n output ports thereof and the shifted pixel data is transferred in parallel from the n output ports of the shift register into the n cells of the output register for sensing by output amplifiers respectively connected to the output ports of the output register.
