  • Publication number: 20130327924
    Abstract: There is provided a solid-state image sensor including unit pixels each including a photoelectric transducer which generates a charge corresponding to an amount of incident light and accumulates the charge therein, a first transfer gate which transfers the charge accumulated in the photoelectric transducer, a charge holding region in which the charge transferred from the photoelectric transducer by the first transfer gate is held, a second transfer gate which transfers the charge held in the charge holding region, a floating diffusion region in which the charge transferred from the charge holding region by the second transfer gate is held to be read out as a signal, and a reset section which resets the charge in the floating diffusion region. The first transfer gate and the reset section are connected to an identical drive section through a drive line shared thereby, and are simultaneously driven by the drive section.

  • Patent number: 8570611
    Abstract: An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.

  • Publication number: 20120153126
    Abstract: Disclosed herein is a solid-state imaging element including: a plurality of unit pixels each having a photoelectric conversion part, a transfer part that transfers a charge generated by the photoelectric conversion part to a predetermined region, and a draining part that drains a charge in the predetermined region; a light shielding film being formed under an interconnect layer in the unit pixels and shield, from light, substantially the whole surface of the plurality of unit pixels except a light receiving part of the photoelectric conversion part; and a voltage controller controlling a voltage applied to the light shielding film. The voltage controller sets the voltage applied to the light shielding film to a first voltage in charge draining by the draining part and sets the voltage applied to the light shielding film to a second voltage higher than the first voltage in charge transfer by the transfer part.
