Abstract: A scanner is provided with a variable aperture lens system. High resolution scans use a relatively small aperture size, and scanning speed is relatively slow. Low resolution scans use a relatively large aperture size, and scanning speed is increased. Fast scans are limited to lower sampling rates, which in turn permit more optical blurring relative to high sampling rates. Accordingly, the incremental cost of the larger aperture is minimized by permitting the lens aberrations specifications to be relaxed at larger apertures. Preferably, an electronic variable aperture is provided, for example, by use of electronically controlled polarization plates or by use of electrochromic substances.

Abstract: By scanning both sides of a photographic print, data from the back of the print may be associated with the image. If the backside data includes text, optical character recognition (OCR) techniques optionally may be used to convert the image of the back of the photo into text that may be included in a database or other data structure allowing the text to be associated with the photographic image. This allows the user to quickly and easily search a large database of images for either a specific image or a group of images according to some set of search criteria.

Abstract: A light emitter is disclosed herein. An embodiment of the light emitter comprises a tube, a first aperture, a second aperture, a lens, a base mechanism, and a light path. The tube has a first end and a second end. The first aperture is located proximate the tube first end and the second aperture is located proximate the tube second end. The lens is located within the tube. The base mechanism is attached to the tube first end and has a cavity formed therein. The light path extends between the cavity and the second aperture and passes through the first aperture and through the lens.

Abstract: An image capture device, such as a scanner, is built including hardware necessary to capture both reflective and transmissive image data from a transparency. The device may associate the two types of data internally or rely on other hardware, such as a controlling computer, to do the association of the two quantities of data. In one possible embodiment, the device would include the ability to perform optical character recognition (OCR) of the reflective data (or the transmissive data, if desired), converting to a type of text format any printing on the transparency.

Abstract: An autochanger has a plurality of media holding bays to hold media pieces. A light emitter and light receiver are placed within the autochanger to establish a light path adjacent the media holding bays. When the light path is disrupted an indication is provided that a media piece is dislodged from its media holding bay. The light emitter has a tube with a light source located adjacent an input end of the tube and a lens located adjacent an output end of the tube. The input end of the tube has a relatively small aperture to limit light passing into the tube and to the lens. The light emitter serves to provide pseudo-collimated light that illuminates a specific light receiver.

Abstract: The present invention is a system that coordinates the printing of a page of photos that match the layout of a pre-existing matte. The matte layout can be created from a physical matte. When creating an electronic layout or template from a physical matte, a digital image of the matte and a reference target is created. The template can then be created by using the relationship in the digital image between the image of the reference target and the image of the physical matte.
