  • Patent number: 8670145
    Abstract: In an image processing system, when a user request is received from a client apparatus, an image processing management apparatus determines whether the user request can be processed by the image processing system to generate a determination result, and generate an instruction indicating how the image processing system should operate based on the determination result.
    Type: Grant

  • Patent number: 4788522
    Abstract: An image sensing device includes a plurality of photoelectric elements arranged in the form of a single array and divided into n number of blocks each of which includes m number of the photoelectric elements commonly connected at one end. In one form of the present invention, a single operational amplifier and m number of switching circuits are used to establish operational independency of the m.times.n photoelectric elements. In other forms, operational independecy of the m.times.n photoelectric elements is established by using an array of blocking diodes or operational amplifiers constructed in the form of IC, but all of the components of a driving or scanning circuit, including these blocking diodes or operational amplifiers, are so structured to be mounted on the same substrate which is remarkably compact in size. Also provided are various forms of photoelectric cells which are particularly suited to be incorporated into an image sensing device and methods for manufacturing the same.

  • Patent number: 4499384
    Abstract: A one-to-one image sensing device having a plurality of photo-receiving elements formed on a substrate in a single array is provided. Each of the photo-receiving elements includes a photodiode and a blocking diode which are connected in series and opposite in direction. These photo-receiving elements are manufactured by the well-known thin-film technology. The photo-receiving elements are grouped into blocks each of which has a predetermined number of photo-receiving elements which are commonly connected on one side. A single shift register is commonly connected to the other side of each of said blocks. A MOS transistor switch is provided between the common junction of each of said blocks and an output terminal of the image sensing device.
