    Abstract: A solid-state imaging apparatus comprises a plurality of unit cell groups including a plurality of unit cells each including a plurality of light shielded optical black pixels, non-light shielded effective pixels and amplifying circuits for amplifying signals from the pixels; and holding capacitors each receiving a signal from corresponding unit cell, so that signals are transferred from all the pixels by a vertical transfer operation and a horizontal transfer operation, each of which is repeated by the number of times equal to the number of the unit cell groups, such that the signals from an optical black pixel and an effective pixel are respectively transferred by the vertical transfer operation and the signals transferred by the vertical transfer operation are successively read out by the horizontal transfer operation to reduce the degrading image quality due to artifact by properly removing an offset varying for each output if it occurs.

  • Patent number: 9007664
    Abstract: A passport and identification card reader minimizes the time and effort required for an operator to read/scan a passport or piece of identification. An immigration official, for example, can slide a passport into place with one hand while tending to other important security activities with the other hand. Once in place, the passport will be automatically detected and read. Numerous passports bound together by a traveler with multiple visas can be held flat in place and accurately read, even with one hand, despite the natural tendency of the passport(s) to return to a closed position.

  • Patent number: 8982432
    Abstract: A light guide includes a plurality of boss portions. A round hole portion is provided near the center of a base member for fixing the light guide, and slit portions are provided on both ends thereof. The round hole portion supports one boss portion in both the longitudinal direction and the lateral direction of the light guide. The slit portions support boss portions in the lateral direction of the light guide, but are free in the longitudinal direction of the light guide. That is, the center of the light guide is fixed from both directions, and thus both ends of the light guides can expand away in the longitudinal direction. This cuts the influence of expansion by half.

  • Patent number: 8976426
    Abstract: A light source driving circuit that drives a light source includes a driving electric current generator that generates a driving electric current including a predetermined electric current, a first auxiliary current, and a second auxiliary current; and a controller that sets values of the first and second auxiliary currents by using first and second lighting pattern signals, wherein each of the first and second lighting pattern signals is for controlling supply of the predetermined electric current to the light source. After setting a first value of the first auxiliary current, a second value of the second auxiliary current is set by using the second lighting pattern signal that defines a time period for stopping supply of the predetermined electric current to be shorter than a time period for stopping the supply of the predetermined electric current that is defined by the first lighting pattern signal.
