Abstract:
Device abstraction units 28a and 28b respectively transmit various pieces of control information and data to and from devices 34a and 34b, and carry out abstraction of the devices 34a and 34b (that is, abstraction of the hardware) with respect to upper constituents. Interface units 22a and 22b transmit various pieces of control information and data to and from the device abstraction units 28a and 28b, and provide an application unit 20 with an identical interface. Communications path abstraction units 24a and 24b carry out abstraction of communications paths 26a and 26b in the process of transmission of various pieces of control information and data via the communications paths 26a and 26b across a process boundary or a network boundary. This arrangement of the present invention enables a substantially fixed control according to an applications program, regardless of the type of the device or the type of the communications path.
Abstract:
A scanner system includes a scanner, computers sharing the scanner, a network connecting between them, and a scanner controlling apparatus connected between the network and the scanner. The computer includes a device driver to control the scanner and notify the scanner controlling apparatus of an event in the device driver, and an application to control the device driver, and transmit and receive data to and from the scanner controlling apparatus. The application activates the device driver in response to the trigger input from the scanner controlling apparatus. When activating, the device driver receives image data from the scanner controlling apparatus through the application.
Abstract:
An image input apparatus includes a reading unit for reading a manuscript image, and a communication unit for transferring the image data, which is read by the reading unit, and control data to another apparatus. The communication unit has a first mode in which a periodic data transfer can be assured, and a second mode in which the periodic data transfer cannot be assured. The communication unit transfers the image data in the first mode, and the control data in the second mode.
Abstract:
An image processing method is performed by an image supply device storing image data and an image output device performing image processing with respect to the image data which are connected via a communication path through which the image data is communicated. It is confirmed whether an extended function for a predetermined function is valid in both of the image supply device and the image output device. It is generated a control information item including a script for image processing which is described by a markup language, in a case where it is confirmed the extended function is valid. The control information item is communicated between the image supply device and the image output device. An extension tag corresponding to the extended function is inserted into the script while remaining an existing tag corresponding to the predetermined function.
Abstract:
An image forming apparatus includes a document control service that generates authentication information corresponding to the request to output a stored document and transmits the authentication information to the network service, and a document output service that receives the authentication information from the network service, obtains the stored document corresponding to the authentication information, and outputs the obtained stored document. After authenticating the stored document, the document control service generates authentication information corresponding to a request to output the stored document from an external network apparatus. The document control service, the external network apparatus, and the document output service can exchange the authentication information instead of the stored document.
Abstract:
According to an information processing method, a device to be accessed is designated, an operation screen is downloaded by accessing the designated device, and information that is entered by a user during the display of an operation screen is transmitted to the designated device as operating information. Therefore, the execution of a process at another device and the employment of a job stored in another device are facilitated. In addition, when designated devices are accessed and logged in, the identifiers for those devices are registered in a device list, and thus, when logout is instructed, since all devices whose identifiers are registered in the device list will be logged out, all the devices that were logged in are logged out.
Abstract:
A wireless communication module with a portable digital camera is provided. The present wireless communication module comprises a wireless adapter for communicating with a wireless communication network, a digital camera for capturing image information, a bus hub for providing ports to the wireless adapter and the digital camera, respectively and a computer host provided with a bus host controller. When the bus hub is pluggable to connect with the computer host, the bus host controller detects the wireless adapter and the digital camera both of which serving as the peripherals of the bus hub, and then loading a corresponding wireless adapter bus driver and digital camera bus driver in an operating system of the computer host. Thereby, the computer host is able to communicate with the wireless communication network via the wireless adapter.
Abstract:
An electronic camera and method of operating an electronic camera which detects whether an external device such as a personal computer is properly connected to the camera and in a state which permits communication. The camera monitors a data terminal ready (DTR) signal of an RS-232 connection in order to determine that the external device is properly connected and in a state which permits communication. Once the proper connection is detected, the camera can either transmit or receive images and/or audio from the external device. Accordingly, a specific switch which places the camera in a communication mode can be eliminated. Further, a single switch may be utilized for both controlling whether the camera records or plays images when there is no device connected, and which controls whether the camera transmits or receives images and/or audio when an external device is determined to be connected.

Abstract:
An electronic camera which detachably connects to a communication interface which allows the camera to communicate with an electronic device such as a personal computer. The communication interface includes circuitry which converts signals utilized by a microprocessor within the camera which are usually within a range of 0 to +5 volts to a level which is utilized to communicate with the computer. When an RS-232 connection is used to communicate between the camera and the computer, the circuitry within the communication interface converts the signals utilized by the camera to a level between -15 and -5 volts for a low signal and +5 and +15 volts for a high signal. The communication interface includes a mechanical connector having two latching mechanisms which connect to receiving members of the camera. The latching mechanisms pivot and are both moved by a single pushing member. The latching mechanisms are constructed as three level elements where the first level includes the latching member, the second level aligns with a level of a frame for supporting the latching mechanism, and the third level includes a surface against which the pushing member pushes.
