  • Patent number: 8368925
    Abstract: An image transmission system 1 includes a digital camera 10, a PC 40, and a Web server 50. This digital camera 10 stores therein a plurality of image data, print request information, and transmission request information. Further, the digital cameral 10 determines whether the connection destination is a printing device or an external apparatus different from the printing device, when a connection with the external unit is detected. The digital camera 10 transmits image data which is associated with the print request information to the print device, when it is determined that the connection destination is the print device, and transmits image data which is associated with the transmission request information to the external apparatus, when it is determined that the connection destination is the external apparatus. PC 40 receives the transmitted image data through a communication network connection 51 and transmits it to the Web server 50.

  • Patent number: 5909688
    Abstract: In an information management system, individual entity information items related to one another are assigned unique identifiers. A smaller number of pointers are used to define high, low, front and rear-rank links among the entity information items. In an entity management table are placed records having a pointer to an entity information item and an identifier of the entity information item. In a structure management table are placed records representing types of the entity information items and having pointers to high, low, front and rear-rank records. There is further provided an identifier management table that relates the types of the entity information items to the identifiers. Use of these tables permits data retrieval in four directions of upward, downward, forward and rearward.
