Abstract: After an ACK is received from a digital video camera (DVC), a DV control program judges whether a transport time-out acquired from a wTransportTimeout field has elapsed or not. If a status change notification is received before the lapse of the transport time-out or if the status change notification cannot be received before the lapse of the transport time-out, the DV control program transmits a status request (a request for requesting status information representative of the current status of DVC) to DVC via a control pipe. With the provision of such a DV control program, it becomes possible to reliably know a change in the status of DVC to a predetermined status by using Universal Serial Bus (USB).

Abstract: An imaging device for transmitting a still image file includes an interface unit and a conversion unit. The interface unit receives, from an external device via a connection between the imaging device and the external device, a control command including first data designating a still image file to be transmitted, second data designating a file type, and third data designating a resolution. The conversion unit converts the still image file designated by the first data into a still image file having the resolution designated by the third data if the file type designated by the second data is a predetermined file type. If the file type designated by the second data is not the predetermined file type, the interface unit transmits, to the external device via the connection between the imaging device and the external device, the still image file at its original resolution.
