An imaging system comprises a calibration system adapted to perform a calibration scan of a charged luminescent calibration strip disposed in a scan window of an automatic document feeder. The calibration system is adapted to determine whether an opaque object is disposed within a visible area defined by the scan window from the calibration scan.

Imaging system and method

Systems are disclosed for detecting an unwanted artifact in an image scanner. An exemplary system includes a treated component of the image scanner, the treated component treated such that light reflects differently from the treated component than light reflected by an image being scanned by the image scanner. The light reflected from the treated component facilitates detection and removal of the unwanted artifact in the image being scanned, the unwanted artifact caused by the light reflected by the treated component.

Image scanner feature detection

A duplex detection imaging system comprises a scanning device having a photosensitive element disposed therein for receiving light reflected from a front surface of a document. The photosensitive element is also adapted to receive light reflected from a back surface of the document while the front surface of the document is oriented toward the photosensitive element for determining whether an image resides on the back surface of the document.

Duplex detection imaging system and method

A method for scanning an image of media comprises biasing a scanner carriage for movement relative to a platen and releasing the carriage to move relative to the platen, the carriage scanning an image with a scanner head disposed therein. An image scanner comprises a housing, a platen disposed on the housing, a carriage disposed in the housing, the carriage comprising a scanner head adapted for scanning an image, a biasable drive moving the carriage relative to the platen for high-speed scans, and a drive mechanism loading the biasable drive for the high-speed scans and moving the carriage relative to the platen for low-speed scans. An encoder for sensing position of a scanner carriage comprises a grating disposed in a scanner housing, and an optical sensor for sensing the grating during biased movement of a scanner carriage, the sensor providing carriage position information for rastering an image of scanned media.

A method of comparing images is disclosed herein. The images may be represented by image data comprising a plurality of image data values. An embodiment of the method may comprise determining at least one image data value representative of at least one first portion of a first image. The method may further comprise determining at least one second image data value representative of at least one first portion of a second image. The at least one first portion of the first image and the at least one first portion of the second image are located in substantially similar regions of the first image and the second image. The at least one first image data value is compared to the at least one second image data value. The first image is similar to the second image if the at least one first image data value is within a preselected amount of the at least one second image data value.

Method and device for sorting similar images

An imager apparatus comprises a pixel and a first filter positioned in an incident light path for a portion of the pixel, the filter being operable to alternate between transmitting and reducing incident light on the pixel portion.

Disclosed are systems and methods for associating images. In one embodiment, a system and a method pertain to capturing an image of image association data, capturing other images to which the image association data is relevant, and associating the other images such that each of the other images will have a file name that is reflective of the captured image association data.

Systems and methods for associating images

A scanner system for imaging a transparent media object comprising an illumination source for concurrently illuminating a first and second scan line of a media object, and a carriage comprising a photosensitive device located within the carriage and a light pipe affixed to a surface of the carriage is provided. The carriage is configured to receive on a first region of the photosensitive device light passed through the first scan line and the light pipe is adapted to redirect light passing through the second scan line onto a second region of the photosensitive device. The photosensitive device is operable to sample light directed onto the first and second regions.

One embodiment of the invention is a button for engaging an electrical switch comprising: a button post that transmits a vertical motion of the button to the electrical switch, an alignment post that registers against the electrical switch and reduces lateral motion of the button, and at least two runners that connect the button to a frame and includes reinforcement that stiffens the vertical motion of the button.

Button having stiffer vertical motion and reduced lateral motion

A memory management method includes, in one embodiment, saving a metadata-generating algorithm in a memory, assigning the metadata-generating algorithm to a metadata field and applying the metadata-generating algorithm on at least one file so that a processor can calculate metadata for a file having no metadata in said metadata field.

Memory management system and method using a hash table

One embodiment of the present invention provides a method of applying user preferences to attributes associated with a digital image, comprising receiving a first digital image from an imaging device, updating attributes contained in a user profile based on user manipulations to the first digital image to create an updated user profile, and applying the attributes contained in the updated user profile to a second digital image.

Manipulating digital images based on a user profile

A method of enhancing resolution in an electronic imaging device includes capturing an electronic image through a fisheye lens with a photodetector at a resolution native to the photodetector. A resolution is selected that is higher than the native resolution of the photodetector. The electronic image is processed to produce a new electronic image at the higher resolution. A fisheye effect caused by the fisheye lens is removed during processing.

A template for a scanner system comprising a template body and an element for generating an optical pattern when scanned by the scanner system is provided. A method of scanning an image on a transparent media comprising executing a reflective scan by the scanner system over a predefined carriage translation distance, comparing data imaged during the reflective scan with a reference pattern and determining subsequent scan procedures based upon the results of the comparison is provided. A scanner system comprising a reflective scanner, a transparent media adapter operable to backlight a transparent media and a template comprising an element for generating an optical pattern when scanned by the reflective scanner is provided.

A scanner comprises a housing including a top wall defining an opening, the top wall of the housing further comprising an upper surface framing the opening. The upper surface of the top wall further comprises a horizontal planar portion and an object removal guide surface between the horizontal planar portion and the opening. A transparent platen supported by the top wall of the housing comprises an upper surface for supporting an object to be scanned, a lower surface parallel with the upper surface of the platen, and a peripheral edge, the horizontal planar portion of the upper surface of the top wall of the housing lying above the upper surface of the platen. The object removal guide surface is (i) positioned relative to the upper, object-supporting planar surface of the platen to permit unobstructed sliding of an object across the peripheral edge of the platen and (ii) configured to raise at least a portion of the object during removal thereof to permit gripping of the raised portion of the object to facilitate removal thereof from the platen.
