Abstract:
When there are very many images stored in a memory card, a time after a computer and a digital camera have been logically connected with each other until the computer and the camera answers a user becomes extremely long. When the digital camera caches the information of a file stored in a storage medium by accessing the storage medium in a reproduction mode, and when the digital camera and the computer are physically connected to each other and they are in a communication mode, information which the computer appears to request finally is generated and stored. After that, when the digital camera receives a data transfer request from the computer, the digital camera transmits stored information to the computer in a lump.
Abstract:
A control system comprises a plurality of peripheral devices represented as objects, and a controller connectable to the plurality of peripheral devices via a common communication line for unitarily controlling the plurality of peripheral devices. The controller is arranged to be connected to an arbitrary number of peripheral devices selected from among the plurality of peripheral devices, read control information stored in the arbitrary number of peripheral devices via the communication line into a predetermined memory area of the controller in a predetermined format so that the controller can control the arbitrary number of peripheral devices. The controller is also arranged to issue a command and transmit the command to each of the arbitrary number of peripheral devices via the communication line.
Abstract:
An external program supplied from an external unit in order to process an image sensed by a camera is prevented from causing a malfunction in the camera. An external program supplied by an personal computer is stored in an EEPROM of the camera. The external program contains version information giving the version of the camera that is capable of using the external program, the name of the program for control, and parameter information corresponding to the program name. A CPU compares each of these items of information with corresponding information that has been set in the camera, thereby determining whether the external program is capable of being used. If the external program cannot be used by the camera, a warning display is presented on a display unit.
Abstract:
An image pickup apparatus in which when a decision button is depressed, a transfer confirmation screen is displayed without recording a selection record, and, when a shortcut button is depressed, a selection record is recorded and the transfer confirmation screen is not displayed. When one of image data recorded in a storage medium is selected by an operation of a user, a reproduction module executes reproduction for display of the image data, and upon a user transfer instruction and acceptance of the instruction by a queue, a communication module transfers image data to an external apparatus. When one of other image data recorded in the storage medium is selected by a user operation in the course of a transfer process of the image data by the communication module, the reproduction module executed a reproduction process on the selected other image data.
Abstract:
A host computer can prevent a peripheral device connected to the host computer from unexpectedly shifting into a non-connection state through control of the host computer. Further, when the peripheral device, such as an electronic camera, cannot receive enough power from a connection line, such as a USB, the peripheral is still able to use the available power effectively. To achieve these objectives, there is a disclosed computer peripheral device connected to the host computer, wherein the peripheral device is comprised of a connection signal transmitter and a controller. The connection signal transmitter is used to transmit from the peripheral device to the host computer a signal to control the connection with the host computer. The controller is used for proceeding a running state of the computer peripheral to a non-connection state, after the connection signal transmitter transmits a signal for a non-connection state to the host computer.
Abstract:
A digital camera of a digital camera system includes an image capture unit and a storing unit for storing the captured image in a memory. A computer of the system issues a capture command for capturing an image by the digital camera or a delete command for deleting the image stored in the memory. The digital camera generates an event signal indicating a change in stored content in the memory by a common sequence when stored content is changed in response to the capture or delete commands and when the stored content is changed in response to a digital camera operation. The computer issues a control command for collecting the stored content by a common sequence in response to the event signal when the stored content is changed in response to the capture or delete commands and when the stored content is changed in response to a digital camera operation.
Abstract:
A peripheral connected to a host computer is prevented from unexpectedly coming to be in a non-connection state due to control of the host computer. Further, even when the peripheral such as an electronic camera cannot enough receive power necessary for the device itself from a connection line such as a USB, the peripheral is made to be able to use the power effectively. To achieve this, there is disclosed a computer peripheral which is connected to the host computer and comprises a connection signal transmitter for transmitting to the host computer a signal to control the connection with the host computer and a controller for shifting an operation state of the computer peripheral to a low consumption current mode after notifying a user and obtaining approval of the user before transmitting a signal to control into the disconnection state to the host computer by the connection signal transmitter.
Abstract:
An electronic apparatus, method, and computer-readable medium shorten the response time of an electronic apparatus such as an electronic camera capable of communicating with an information processing apparatus such as a computer, and improve the usability of the information processing apparatus when the information processing apparatus requests data stored in the storage medium of the electronic apparatus. The electronic apparatus, which has a main storage device and an auxiliary storage device, is connected to an external apparatus, and can transmit/receive data to/from the external apparatus. Data to be requested by the external apparatus is loaded in advance from the auxiliary storage device to the main storage device before the external apparatus requests the data after connection to the external apparatus is established.
Abstract:
When a digital camera 100 is connected to an information processing apparatus 101 so that they can communicate with each other, the digital camera 100 generates partial information of attribute information related to each image data stored in the camera 100, and transmits the partial information of the attribute information to the information processing apparatus 101.
Abstract:
A personal digital assistant 1 composed of a main body 2 formed with an operation section 212; a cover body 3 which is freely attached and slides parallel to the operating section 212 from a position overlapped on the operation section side of the main body 2; and an energization spring 45 formed in the cover body 3 which applies force along a direction which maintains an opened state in an opened position where the cover body 3 has been made to slide from the main body 2. Accordingly, a sliding type personal digital assistant can be stabilized in a closed position and/or an opened position and prevent opening or closing in a midway through position.
