There is provided an image pickup apparatus comprising a plurality of pixels each including a photoelectric conversion unit which converts incident light into an electrical signal and accumulates the electrical signal, an amplifier transistor which amplifies and outputs the signal from the photoelectric conversion unit, a transfer transistor which transfers the electrical signal accumulated in the photoelectric conversion unit to the amplifier transistor, and a processing transistor which performs predetermined processing, and a control circuit which sets the signal level supplied to the control electrode of the transfer transistor in order to turn off the transfer transistor to be lower than the signal level supplied to the control electrode of the processing transistor in order to turn off the processing transistor.

Image pickup apparatus

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.

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.
