Abstract: A control method for an electronic device such as a digital camera, having a mechanical driving member comprising a collapsible barrel, a lens barrier and the like, which performs mechanical operations, and a system controller which controls the overall device including the mechanical driving member is provided. In accordance with turning on of power supply to the system controller, the mechanical driving member is driven until the device enters a main-operation stand-by status, in parallel to start of an OS by the system controller.

Abstract: In order to realize to improve safety performance of a filing system by satisfying the minimum requirement of protecting the filing system even if a shooting operation is performed in any condition, management information of a file for a shot image is to be priorly written in a storage medium, and the management information of the filing system is to be updated immediately after performing the shooting operation even if the shooting operation is performed in any condition. Accordingly, even if an unexpected accident such as detaching of a storage medium or extraction of a power supply unit by a user is happened, since the minimum requirement of protecting the filing system is satisfied, it is possible to prevent a state that image data which was already shot can not be accessed.

Abstract: In a processor system having a CPU, a RAM, and a communication portion for external communication, the operation of the central processing unit is stopped when an IPL operation mode is selected by an operation mode selection switch. An IPL program transferred from the outside through the communication portion is then written to the RAM starting from a predetermined address, and the stoppage of the operation of the CPU is thereafter canceled. The CPU restarting the operation executes the IPL program written to the RAM by first reading the predetermined address to download a system program. Since the IPL program is transferred from the outside, the IPL program to be used can be easily changed.

Abstract: There is provided an image pickup apparatus that is capable of easily displaying in a distinguishable manner image data when the image data is photographed by a plurality of image pickup apparatuses, transferred (copied or moved) between the image pickup apparatuses and displayed by one image pickup apparatus. An image data photographed by an image pickup device is recorded by a recording device and the image data recorded is displayed by a display device. The recorded image data is transmitted and received by a communication device that is connectable to a plurality of image pickup apparatuses. Unique apparatus information for identifying the image pickup apparatus to the photographed image data is allotted to the photographed image data.

Abstract: A system includes a computer and digital camera connected to each other; automatic image transfer or remote control can be achieved readily, and a power supply route is simple. A card connector for an I/O card and a back connector thereof are linked by a power supply line. When the I/O card is connected to a digital camera, power supplied over an interface cable joined with the back connector is supplied to the digital camera. Moreover, when the I/O card is connected to the digital camera, a start-up instruction signal is sent from the I/O card to the digital camera. A CPU in the digital camera executes start-up processing.
