Abstract:
The data sending and receiving controller (104) of sender's communication device (100) sends data with its mode information such as graphic resolution to receiver's communication device (200). The operator at receiver's communication device occasionally requests for re-sending once received data according to the mode information received with the data when the receiver is not satisfied with the data because its resolution is too low etc. The sender's communication device (100) analyzes the content of request and re-sends data with the mode corresponding to the content of request when it is sent from the receiver's communication device (200).
Abstract:
An image reading apparatus reads image information of an original document to produce image data having different data sizes. An image converting section converts the image information into a plurality of items of image data. A display section displays a plurality of items of information on the plurality of items of image data. A selecting section allows selecting of one of plurality of items of image data.
Abstract:
In an image forming device, a ground-tint detection unit detects a ground-tint pattern in an original image based on image data output from an image reader unit. An image invalidation unit outputs a processed image data that makes the image data of the original image illegible, when the ground-tint pattern in the original image is detected. A resolution setting unit allows a resolution of the image reader unit to be higher than a minimum resolution needed for detection of a ground-tint pattern and stored in a memory unit.
Abstract:
A method of printing a document using one of a plurality of print modes, the method comprising: (i) notionally dividing a digital image of the document into sectors; (ii) for each sector, comparing one or more properties of the luminosity of pixels within each sector with one or more threshold values; (iii) using the comparison of (ii) to determine whether each sector is likely to show an image defect if printed at a lower image quality print mode; (iv) selecting a print mode such that all sectors are determined not to be likely to show an image defect; (v) printing the document using the determined print mode.
Abstract:
In a display apparatus capable of multiple-view display, a restriction is imposed on an image to be displayed depending on the viewing area set with reference to a screen, thereby enhancing security and preventing leakage of confidential information. When an image processing apparatus outputs an image to the display apparatus, the image processing apparatus confirms the display conditions for a specified viewing area. After confirmation, the image processing apparatus reads an image of a document according to the display conditions. The image to be outputted is restricted and differs from the original image. The image processing apparatus transmits the restricted image to the display apparatus. The display apparatus displays the restricted image, which is different from the original image, to the specified viewing area. The display apparatus displays the original image to the other viewing areas.
Abstract:
A driver of the invention adapts to scan peripherals using information in capability descriptor provided by scan peripherals or a capability descriptor selected based upon scan peripheral model information. A driver of the invention automatically determines a scan peripheral's capabilities using information from the capability descriptor, and uses the information to configure itself from a set of driver modules. A user interface and scan job are then run through options enabled by the appropriate set of driver modules as determined by the capability descriptor. A preferred embodiment server of the invention embodies such an adaptive driver that queries a scan peripheral when it is first connected to the server. If an appropriate capability descriptor is obtained in response to the query, the capability descriptor is stored for use during a scan job. When a scan job using that peripheral is requested, user interface code extracts information from the capability descriptor to allow the user interface to dynamically change dependent upon the peripheral's capabilities as indicated by the information from the capability descriptor. Capabilities indicated by a capability descriptor might include, for example, dots per inch choices, paper sizes, color/grayscale options, image formats, and whether or not a preview scan is supported. The appropriate capabilities become selectable through a user interface at a client computer. When a scan job is directed, scan driver software/firmware uses selected parameters passed by the client and the information from the stored capability descriptor to determine an appropriate command protocol and image encoding. A set of driver modules is then dynamically linked to create an appropriate driver for the scan job.
Abstract:
In an image scanning apparatus, documents on a document tray are transferred one by one, and an upper surface height of the documents is lowered to turn off a height detection sensor. Different kinds of control modes are performed according to a document scanning mode. In an image-quality-priority scanning mode, a transfer unit suspends transfer of the document, the document tray is elevated until the upper surface height reaches a target height that is higher by a predetermined distance after the height detection sensor is turned on, and the transfer unit resumes the transfer of the document. In a speed-priority scanning mode, while the transfer of the document is continued by the transfer unit, the document tray is elevated until the document tray reaches the target height.
Abstract:
There is provided a method of determining an optimal image transmission method when image data is transmitted from an image supplying device 1 and 1′ to an image display device 2 and 2′, the method including: before the image data is transmitted after a transmission path from the image supplying device 1 and 1′ to the image display device 2 and 2′ is established, determining the image transmission method on the basis of correspondence table, which is previously prepared, such that the optimal image transmission method according to at least one of transmission path information and capability of the image display device 2 and 2′ acquired by the image supplying device 1 and 1′ is derived.
Abstract:
An optical disk device includes a read means which reads an image signal from an optical disk, and a conversion means which converts this image signal to one designated resolution. Furthermore, this optical disk device is connected to a display device which displays an image of this converted image signal. Moreover, this optical disk device includes an actuation means which receives input of one resolution among the first plurality of resolutions. And this optical disk device also includes a control means which acquires a second plurality of resolutions from the display device. And, when one resolution is inputted by the actuation means, this control means decides whether or not this input resolution is included in the second plurality of resolutions. Moreover, if it has been decided that the input resolution is included in the second plurality of resolutions, the control means designates that input resolution to the conversion means.
Abstract:
When a read resolution set for a reader unit (200) is different from the transmission resolution, the read resolution is increased, and then the reader unit (200) reads an image. When the image read by the reader unit (200) contains the first encoded image obtained by encoding input information, the first encoded image is decoded to restore the input information. The restored input information is encoded at the transmission resolution to generate the second encoded image. The second encoded image is transmitted to the destination.
