  • Patent number: 10848638
    Abstract: A processing system includes a storage unit that receives and stores information on electronic equipment from an equipment control unit, and a command relay unit that receives a control command from an information processing unit that performs processing which is based on the information stored in the storage unit. The command relay unit transmits the control command along a second communication path that is different from a first communication path that is a communication path between the information processing unit and the equipment control unit with the storage unit in between, and thus performs relay of the control command between the information processing unit and the equipment control unit.

  • Patent number: 10542199
    Abstract: An image capture apparatus includes an image capture unit, a communication unit, and a control unit which communicates with an external device by first or second communication systems. The first system maintains communication connection even if the apparatus and device are not in a predetermined operational mode for executing image transmission processing. The second system maintains communication connection if the apparatus and device are in the predetermined mode. The control unit can automatically transmit a photographed image to an external device through the communication unit by the second communication system, and switch and control first and second functional modes for enabling and disabling a photography function, respectively. Where an image is photographed in the first mode, the control unit records the image as a target for automatic transmission. If the transmission target image is recorded, automatic transmission is not started during the first mode, and started during the second mode.
