Abstract:
An optical scanner may be used either with or without a support stand. When operated without the support stand, the scanner may be used to acquire an image of an object in virtually any location and/or orientation, e.g., an image of a picture hanging on a wall. When used in conjunction with the support stand, the support stand may hold the scanner in a non-horizontal orientation so that the combined scanner and support stand occupy a relatively smaller footprint. The scanner may attach to the support stand such that it is able to pivot with respect to the support stand. An object to be scanned (e.g., a document) may then be placed on a support surface of the support stand and the scanner pivoted to a closed position to allow scanning of the object. In this manner, the scanner may also be used in a manner similar to a conventional flatbed scanner.
Abstract:
A system and method for presenting and capturing images on a presentation board are described. More particularly, embodiments of the present invention provide a projector adapted to display one or more images onto a surface and a camera adapted to capture the one or more images from the surface. Also provided is an interface electronics coupled to the projector and to the camera. The interface electronics is adapted to feed the projector with the one or more images and adapted to process the one or more images from the camera. Also a user can control the presentation system by modifying the one or more images on the surface.
Abstract:
A projection surface on which a predetermined projection image is projected is provided; a writing surface on which an image can be drawn directly in a superimposing manner with a projection image displayed on the projection surface is provided; and a photography part photographing an image drawn on the writing surface by means of an image-pickup part comprising two-dimensionally-disposed pixels is provided.
Abstract:
A method and apparatus for receiving document images including portions linked to one or more electronic addresses. The linked portion of the document is identified using a predetermined visual attribute, such as bold-face text, or delimiters to mark the portion. The document image is then transmitted using, e.g., existing apparatus for transmitting images, such as a facsimile machine. An electronic address associated with the identified portion of the document is also transmitted using existing techniques, such as by touch-tone telephone. The address may be a voice telephone number, facsimile telephone number, World Wide Web address, or any other address with which communication can be established. At the receiving end, both the document image and electronic address are received. Pattern matching is performed on the document image to identify the portion with the predetermined attribute as a linked portion. The received electronic address is then correlated with the linked portion. When the document image is displayed on, e.g., a computer screen, the linked portion is visually identified so that the recipient can access the electronic address by, e.g., clicking on the portion using a mouse. Communication may then be initiated by the recipient with the entity associated with the electronic address.
Abstract:
An input/display integrated information processing device has: image display circuit for displaying document and image information; image input circuit through which information of an image such as a picture, a photograph, documents drawn or written on a sheet presented by the user can be an input; a visual coincidence structure for integrally combining a display screen of the image display circuit with an input screen of image input circuit so as to establish visual coincidence of screens as viewed from the user; contact information detection circuit for, when a finger of the user, the sheet presented by the user, or the like makes contact with the contact information detection circuit, detecting information of a contact position, the contact information detection circuit being disposed on the whole of the input screen of the image input circuit or the display screen of the image display circuit; image extraction circuit for automatically extracting only a required portion from image information input through the image input circuit; image information storage circuit for storing the image information; image synthesize circuit for combining the image with an image which is already displayed and stored; and image information control circuit for controlling input/output operations of the image information.
Abstract:
An attachable printer for use with a electronic camera having an image sensor which captures an image of a subject onto the image sensor is disclosed. The camera includes electronics coupled to the image sensor for storing a digital image of the subject; a display; and circuitry coupled to the display and responsive to the stored digital image and effective in a first condition for producing a correctly oriented image on the display and in a second condition for producing a mirror image on the display. The printer is effective when connected in operative relationship to the display and having a moveable carriage, and a scanner and an ink jet printhead mounted on the carriage, and being arranged so that as the carriage moves, the scanner scans the mirror image on the display and produces image signals; and the ink jet printhead being responsive to the signals produced by the scanner for producing a correctly oriented image onto the receiver sheet.
Abstract:
An image scanning device is provided for reading an image of an object. The image scanning device includes: a linear image sensor outputting an image signal corresponding to a received image; an imaging lens positioned between the object and the image sensor; a scanning system rotatable through a predetermined scanning range around a predetermined axis parallel to the line of image receiving elements to scan an image of the object onto the image sensor; a focusing system for adjusting a focusing condition of the image scanning device; and a controller which, based on an image signal from the image sensor, adjusts the focusing system to set an in-focus focusing condition for a portion of the object located at a substantially central portion of the scanning range. The image scanning system may be set to the center of the scanning range and the controller, using image signals from the image sensor, may monitor the contrast of the image while adjusting the position of the imaging lens until the contrast is maximum.
Abstract:
A method for controlling an image processing system comprising a fax-terminal and an image scanner connected to each other involves producing image signals by the image scanner and inputting them into the fax-terminal. When the fax-terminal accesses a telephone circuit, and if an original document is set in the fax-terminal, an image of the original and then the image picked up by the image scanner are transmitted in succession by facsimile. If the fax-terminal does not access a telephone circuit, the image signals from the image scanner are supplied to the fax-terminal which makes a hard copy of the scanned image. When the scanned image has been transmitted, a hard copy of the transmitted image can be made by the fax-terminal after the access to the telephone circuit is released. The access between the telephone circuit and the fax-terminal is maintained for a predetermined time interval after one image frame has been picked up and transmitted. This access is continued if a reservation for the next image frame transmission is made within this time interval. It is therefore possible to pick up and transmit a plurality of images to a remote fax-terminal after inputting the address of that terminal once. When the fax-terminal receives a polling signal from a remote fax-terminal, the image scanner is actuated to pick up and transmit image signals to the remote fax-terminal.
Abstract:
An electronic blackboard having a copy function, and an edit function or communication function. A single reading unit is used in common for both reading an image on a flat board and reading an image or an original document. Reflected light from the flat board and from the original document is converged and projected onto a light receiving surface of a single photoelectric conversion element. An image of the flat board of the original document can be selectively read, or the composite image of both the flat board and original document can be read. Further, the electrical signal corresponding to the image can be modulated and transmitted, and a received electrical signal can be demodulated to reproduce a corresponding image. Furthermore, in accordance with the electrical signal obtained by photoelectrically converting an image, the layout of the image on the flat board can be determined and edited to change the shape of the image.
