Abstract: An electronic device provided with a multimedia interface having a cross-device control function and a general-purpose serial bus interface is provided with a control unit that prohibits the use of the cross-device control function whenever an external device is connected via the general-purpose serial bus interface during a state permitting control by the cross-device control function from an image display device connected via the multimedia interface.

Abstract: An imaging apparatus includes a connector that is directly connectable to a bus of an information processing apparatus that is separate from the imaging apparatus. This enables the set-up of the various parameters of the imaging apparatus to be performed rapidly while the imaging apparatus is directly electrically connected to the bus of the information processing apparatus, which can be, for example, a personal computer. The connector is coupled to a controller of the imaging apparatus. The imaging apparatus can also include a photographic lens and a photoelectric converter arranged relative to the photographic lens to receive light focused by the photographic lens. The photoelectric converter outputs an image signal of an object based on the image formed by the photographic lens. The controller is coupled to the photoelectric converter to control the imaging apparatus. According to one embodiment, the connector is a Personal Computer Memory Card International Association-conforming connection terminal.

Abstract: Thumbnail images are promptly created while reducing the required memory capacity for storing the thumbnail images. When input (of an image or a command) is not completed in more than a prescribed time period, only the picture images photographed on that day from among the photo-images stored in a memory are read to create thumbnail images. The created thumbnail images are stored in a buffer memory. When set to the reproduction mode, the thumbnail images stored in the buffer memory are read and displayed on a screen in a list format. Furthermore, when the power is in the OFF position, the thumbnail images stored in the buffer memory can be deleted.

Abstract: An image processing device such as an electronic camera prevents external devices from writing to a first storage region of a memory, while allowing the external device to write to a second storage region of the memory. Accordingly, even when the external device operates irregularly, information stored in the first storage region cannot be erased or corrupted. According to a second aspect, two connectors provided on the electronic camera so that the camera can be attached to different external devices are arranged on the outer housing of the camera so that when the first connector is connected to an external device, the second connector is covered. Conversely, when the second connector is connected to an external device, the first connector is covered. This prevents both connectors from being simultaneously connected to two different external devices, and lessens the possibility of causing an excessive voltage within the camera.
