  • IMAGE PICKUP APPARATUS, METHOD FOR DRIVING IMAGE PICKUP APPARATUS, IMAGE PICKUP SYSTEM, AND METHOD FOR DRIVING IMAGE PICKUP SYSTEM
    Publication number: 20130321683
    Abstract: An image pickup apparatus, a method for driving the image pickup apparatus, an image pickup system, and a method for driving the image pickup system output a digital signal based on a difference between signals output from a plurality of pixels and a digital signal based on the sum of the signals output from the pixels.

  • IMAGING APPARATUS, IMAGING SYSTEM, IMAGING APPARATUS DRIVING METHOD, AND IMAGING SYSTEM DRIVING METHOD
    Publication number: 20130229555
    Abstract: Pixels output a first signal based on signal charge of a part of photoelectric conversion units of multiple photoelectric conversion units, and a second signal based on signal charge of multiple photoelectric conversion units. An imaging apparatus outputs signals based on the first signals and signals based on the second signals by reducing the number of signals based on the first signals as compared to the number of signals based on the second signals.

  • IMAGING APPARATUS, IMAGING SYSTEM, AND IMAGING APPARATUS DRIVING METHOD
    Publication number: 20130229543
    Abstract: An imaging apparatus, driving method of the imaging apparatus, and an imaging system, are provided, wherein pixels output at least two image signals with different viable signal ranges, and the pixel signal with a larger signal range is converted to a digital signal during a first period, and the pixel signal with a smaller signal range is converted to a digital signal during a second period shorter than the first period.
