  • Patent number: 8885076
    Abstract: Systems and methods for camera sensor defect correction and noise reduction are disclosed. In an exemplary implementation, a method may include comparing a pixel in a digital image to neighboring pixels to identify an anomaly. The method may also include ignoring the anomaly if the anomaly occurs in at least one neighboring pixel, and marking the pixel as defective if the anomaly does not occur in any neighboring pixels.

  • Patent number: 7548689
    Abstract: In a method for processing an image, a scene to be captured is divided into multiple zones and statistical values for a plurality of the multiple zones are obtained. In addition, a short-exposure time and a long-exposure time from the statistical values of the plurality of zones are determined. A long-exposure frame is captured at the long-exposure time and a short-exposure frame is captured at the short-exposure time. The long-exposure frame and the short-exposure frame are combined into a combined image while correcting for motion estimated to have occurred between the long-exposure frame and the short-exposure frame, and the combined image is stored.

  • Patent number: 7312905
    Abstract: A scanning method that provides a quick start to the first scan and maintains the quality level of the final scan is disclosed. The first scan, or preview scan, is done without waiting for the lamp to stabilize. The time between the preview scan and the final high quality scan is used to stabilize the lamp.

  • Patent number: 7123295
    Abstract: An image capturing device includes a processor, at least one interface, and a memory. The memory is capable of storing a plurality of records. A record includes image storage data, date/time data, and status data. The processor determines whether any of the images in the memory have been archived as indicated by the status information in the status storage cell of the records, and replaces one or more archived images with newly captured images as the device is used.

  • Patent number: 7116361
    Abstract: In a digital camera, images are stored in chronological order in an image storage queue, and the ability of the camera to add additional images to the queue is related to the archival status of the images already in the queue.

  • Patent number: 7106369
    Abstract: An image capturing device comprises an audio transducer, a processor, and a memory. The memory receives an audio signal produced by the audio transducer and gated by the processor. The memory includes an audio buffer capable of continuously accumulating the audio signal until the buffer becomes full, and thereafter storing a predetermined time amount of the most recent audio signal. The memory further includes one or more audio storage cells capable of storing at least a portion of the audio signal held in the audio buffer. The processor is capable of storing at least a portion of the audio signal from the audio buffer into an audio storage cell of the one or more audio storage cells.

  • Patent number: 7079707
    Abstract: The present invention includes a system and method for the correction of user induced inadvertent orientation errors in captured digital images before the digital image is saved to a storage media or memory. A system of the present invention checks a user-selectable input to determine if the orientation correction has been enabled, enables a tilt determining mechanism which senses orientation errors when the feature is enabled, corrects the orientation errors in the viewed image, displays a corrected digital image to the user and allows the user to store a digital representation of the corrected image into a memory. The method of the present invention includes receiving a digital representation of an image, identifying vertical or horizontal lines contained within the image, determining an orientation error, rotating the digital representation of the image to reduce the orientation error and displaying a corrected digital image.

  • Patent number: 7027662
    Abstract: An image without use of a flash is taken, along with an image using a flash. A difference image is generated by subtracting the flash-less image from the flash image. A threshold is applied to the difference image such that only large differences in intensity remain in the difference image. This artifact image is then subtracted from the flash image, thereby removing flash artifacts such as specular reflections and red-eye. The threshold used may be automatically calculated or may be set by the user. For some applications it may be desirable to set separate thresholds for each dimension of the color space (such as red, green, and blue) used. Once again these separate thresholds may be automatically calculated or may be set by the user.

  • Patent number: 7003654
    Abstract: An electronic information retrieval device includes a time source, a communication interface capable of communicating with one or more external devices, and at least one I/O device. The electronic information retrieval device further includes a memory storing a plurality of time values and storing a corresponding plurality of time-based initialization default values. The electronic information retrieval device obtains a current time value from the time source upon initialization of the device, compares the current time value to the plurality of time values, retrieves a corresponding particular time-based initialization default value from the plurality of time-based initialization default values, and uses the particular time-based initialization default value in the initialization.

  • Patent number: 6963365
    Abstract: A device, preferably a digital camera, has an imaging sensor providing a digital representation of an image projected onto an imaging portion of the imaging sensor. A processor associated with the device identifies an image compression factor and progressively, over a selected region of the digital representation of the image, magnifies at least a portion of the digital representation of the image to reduce an apparent convergence distortion. Correction preferably occurs before lossy compression. The device preferably includes a display to provide a visual display of the digital representation of the image to a user who may use a user input to manually correct apparent distortion by following prompts generated on the display. The device also preferably includes a non-volatile memory configured to store the digital representation of the image.

  • Patent number: 6945645
    Abstract: A method and apparatus for printing and scoring media in a printing system. In one embodiment a scoring pattern is based upon input by the user on a graphical user interface. The system typically incorporates a controller that drives a scoring printer having a scoring head with one or more pins or wires that impact the surface of media and weaken the media. By creating a predetermined pattern of impacts, the media is weakened along a region or line for subsequent separation.
