  • Patent number: 7576788
    Abstract: The output voltages of dark pixels and optical black (OB) pixels are different between a row including a pixel which receives strong light and another row. An image formed upon receiving a strong light spot suffers whitish bands on the right and left of the spot. To solve this problem, this invention provides an image pickup apparatus including a pixel containing a photodiode which converts a photo-signal into a signal charge and accumulates the signal charge and an amplifier transistor which amplifies the signal charge accumulated in the photodiode, and a control element adapted to limit the output of the amplifier transistor so as to prevent the output from falling to below a predetermined voltage.

  • Patent number: 7437315
    Abstract: This disclosure relates to a method and apparatus for implementing online sales in an environment on a network, which is provided by a creator, without putting any load on the creator. A creator-side apparatus transmits a content that forms merchandise and merchandise information about its output medium to a support-side apparatus. The support-side apparatus makes the merchandise information correspond to an address that indicates a location on the network and transmits the address to the creator-side apparatus as an address where an order for the merchandise should be received. The creator-side apparatus sends data containing the address to the network to which an orderer-side apparatus is connected such that the orderer-side apparatus accepts connection to the location. The support-side apparatus executes merchandise order reception processing when the orderer-side apparatus is connected to the location and requests an output system to execute output processing based on the merchandise information.
