Abstract:
A transparency adapter for use with a scanner comprising a scanner light source, a scanner platen and a scanner lid. The transparency adapter comprises a light table comprising a stationary light source separate from the scanner light source. The stationary light source comprises a light table operating state for illuminating transparent media for viewing and a transparency adapter operating state for illuminating transparent media while it is being scanned by the scanner, thereby creating a scanned image of the transparent media, the scanned image having an output orientation. The transparency adapter further comprises at least one mounting device on the light table to hold the transparent media in an input orientation during the light table operating state.
Abstract:
An image reader apparatus includes: an image pickup device which is controllably exposed to an object to produce an image signal of the object; a mover which moves the object and the image pickup device relative to each other; a storage operable to store an image signal; a writing device which is operable to write an image signal in the storage; a reading device which is operable to read an image signal from the storage; a discriminator which discriminates whether one of the writing device and the reading device is in operation; and a controller which controls the exposure of the image pickup device in accordance with a result of the discriminator.
Abstract:
In order to accurately perform correction of focal distance and color of film before pre-scanning, the image at the generally center area of the first frame of film is read in a first pre-scan, auto-focusing and judgment between negative/positive is made, exposure parameters are set in a second pre-scanning, and the image is read in main scanning.
Abstract:
A scanner system digitizes 35 mm transparencies or negatives, and converts the image to a format compatible with popular microcomputer systems. This scanner system can accommodate various formats, and has variable zoom, pan and window size. Color separation is accomplished by an illumination arrangement causing rapid sequential generation of red, green and blue components. A low wattage light source is used, and color balance is achieved by adjusting the respective exposure times of the three primary colors. The system has internal calibration to achieve repeatable color balance. The system implements a wide variety of color coding schemes ranging in resolution from 1 to 24 bits. An adaptive process compresses the data in order to optimize the color selection process. The illumination optics are anamorphotic for high efficiency. Mechanical and electrical interfaces are compatible with a conventional 51/4" floppy disk drive standard.
Abstract:
A photographic slide-to-video tape converter having an elongated supporting base, a video camera mount associated with the base for detachably securing a video camera to the base with the camera lens in a predetermined position, support structure projecting from the base, a photographic slide carrier structure for supporting a slide for imaging by a camera connected to the base, and a light directing unit for directing light through a slide supported by the slide carrier into the lens of a video camera secured to the base. The slide carrier structure has a slide positioner and slide engaging assembly for receiving and supporting a slide at a predetermined position in alignment with the camera lens position. The light directing unit directs light through the slide to the camera lens.
Abstract:
A film-to-tape transfer apparatus suitable for transferring images from movie film, slide film, photograph and the like which includes a case body having a bottom plate therein, a rotary shaft rotatably installed on the bottom plate and having a manipulating knob mounted on the top portion thereof, a supporting member secured to the rotary shaft, a reflecting mirror attached to the supporting member, a glass screen unit provided on the rear side of the case body, a macro-lens provided on the left side of the case body, a fluorescent lamp installed at the right portion inside the case body, a transparent and pushing plate provided on the right side of the case body and slightly spaced with each other for receiving a photograph to be recorded, and a sound mixing unit for controlling the sound to be recorded on the video tape.
Abstract:
A color slide transparency scanner projects an intense stripe of light through a color slide. Red, green, and blue filters successively filter the stripe of image from the slide. In some applications, a neutral density filter adds still more information from dark areas of the slide image. A carriage carrying the slide moves across the light. A CCD array detects the filtered images and converts them to analog electrical signals. Circuitry converts the analog signals to digital.
Abstract:
In a film video system, a repositionable imaging solid state sensor is used to generate electric signals in reponse to a photographic image for display on a video monitor. The repositionable sensor is aligned with the photographic image by locating a fixed mask between a source for illuminating the image and the sensor. Corner pixels of the sensor are identified, and the sensor is moved relative to the mask. When at least one of these corner pixels transition between a light and dark state during movement of the sensor, it is indicative of the presence of an edge of the mask. By moving the sensor and calculating the distance between edges of the mask, the sensor may be aligned with the mask. Since the mask is aligned with the photographic image, the sensor is aligned with the photographic image.
Abstract:
An image processing apparatus is capable of reading an original image with an arbitrary image magnification, by projecting an original image onto a linear image sensor through an optical system of a variable image magnification, and moving the original image with respect to the image sensor with a speed corresponding to the selected image magnification of the optical system.
