Abstract
The photoelectric conversion device includes a photoelectric conversion element configured to convert light reflected from an original image to electrical signals and a clock generator configured to generate driving signals for driving the photoelectric conversion element from a reference clock. Each of the driving signals is generated using the same logic gate or substantially the same logic gate.
Claims10
A photoelectric conversion system comprising:
- a timing generator configured to generate a timing signal;
- a CCD driver configured to generate a reference clock based on the timing signal;
- and
- a photoelectric conversion device including:
- a photoelectric conversion element configured to convert light reflected from an original image to electrical signals, and
- a clock generator configured to generate a plurality of driving signals for driving the photoelectric conversion element from the reference clock, each of the driving signals being generated using the same type of logic gate.

2 more elements
A photoelectric conversion device comprising:
- a photoelectric conversion element configured to convert light reflected from an original image to electrical signals;
- and
- a clock generator configured to receive a reference clock from a CCD driver, the reference clock being generated based on a timing signal transmitted by a timing generator to the CCD driver, and to generate a plurality of driving signals for driving the photoelectric conversion element based on the second reference clock, each of the driving signals being generated using the same type of logic gate.
