  • Patent number: 7508444
    Abstract: An electronic camera includes a sensor for capturing an image, an electronic image display for displaying the captured image, and a user interface for selectively enabling a quick view feature in which the image display is automatically turned on for a set period of time after an image is captured, and then automatically turned off, in order to quickly review the captured image. The camera further includes a processor for performing processing on the captured image and generating a processed image file therefrom, and a memory for storing the processed image file. When an erase command is provided to the processor, the processing of the image file is terminated and the partially completed image file is deleted from the second memory.

  • Patent number: 7327390
    Abstract: In order to reduce image degradation due to image capture problems, a method utilizes image data corresponding to a captured image and image capture metadata that refers specifically to information that is associated with capture of the image. A database of correction parameters is provided in order to reduce degradation present in the captured image, whereby each correction parameter is associated with particular image capture metadata. The method involves using the image capture metadata to determine whether the database contains one or more correction parameters associated with that image capture metadata, and then producing correction parameters from the database of correction parameters when the database contains correction parameters associated with the image capture metadata. One or more new correction parameters are produced when the database does not contain correction parameters associated with the image capture metadata. The database then may be updated with the new correction parameters.

  • Patent number: 7212668
    Abstract: A system and method for automatically altering an image having pixels is disclosed. An image is segmented into regions and various features of the regions are extracted and used to calculate a confidence factor, or belief value, that a particular region is a main subject of the image. The belief values are assembled into a belief map that is used to define how pixel values are to be altered. Various color and appearance values of the pixel are altered in a predetermined way to emphasize the main subject of the image. The emphasis is applied in a binary fashion or as in a gradient of values. Either the main subject can be emphasized, or the secondary or background subjects can be de-emphasized. The system can be implement on a variety of computer systems.

  • Patent number: 7200277
    Abstract: A JPEG2000 compressed image is transcoded to a lower bit-rate or lower resolution, or both, without having to decompress the initial JPEG2000 image and then recompress it to a lower bit-rate and/or resolution. Instead, arithmetic decoding is performed only to the nearest higher bit-rate layer, up to the desired resolution, before performing rate-distortion optimization to produce the transcoded image.

  • Patent number: 7194112
    Abstract: Deriving a three-dimensional panorama from a plurality of images of a scene generated by a range imaging camera of the type that produces ambiguities in range information includes the steps of: (a) acquiring a plurality of adjacent images of the scene, wherein there is an overlap region between the adjacent images and at least some of the adjacent images are range images; (b) providing offset data for the range images in order to recover corrected relative scene spatial information and provide a corrected range image, and (c) deriving a three-dimensional panorama from the corrected range image. In order to provide offset data, a relative range difference is detected between adjacent range images as a constant offset between the adjacent images; and the constant offset is applied to at least one of adjacent range images to correct for ambiguities in the relative ranges of the range images.

  • Patent number: 7170552
    Abstract: An electronic still imaging system employs an image sensor comprised of discrete light sensitive picture elements overlaid with a color filter array (CFA) pattern to produce color image data corresponding to the CFA pattern, an A/D converter for producing digital CFA image data from the color image data, and a memory for storing the digital CFA image data from the picture elements. A processor enables the processing of the digital CFA image data to produce finished image data, and the digital CFA image data and the finished image data are both stored together in an image file. This enables image processing from raw camera data to final output data to be completed in a single, integrated process to provide improved image quality when printing.

  • Patent number: 7171055
    Abstract: A method for reducing the visibility of sub-Nyquist aliasing artifacts in an image, where the image is produced in a scene-to-output imaging system that is represented by a modulation transfer function, includes the steps of: (a) providing a source image signal as an input image having sub-Nyquist aliasing artifacts, where image content is represented by an image frequency response and a frequency response amplitude; (b) determining a preferred aliasing ratio by utilizing an aliasing equation that depends on image frequency and pixel count of the imaging system; and (c) adjusting the frequency response amplitude of the image signal for image frequencies corresponding to the preferred aliasing ratio so as to correspondingly adjust the modulation transfer function of the scene to output system to maintain the preferred aliasing ratio while reducing the frequency response amplitude, thereby providing an image with reduced visibility artifacts.

  • Patent number: 7139437
    Abstract: In a method for removing artifacts in a digital image that has been decoded from a compressed representation of the image, the pixels of the digital image are segmented into low detail pixels, high detail pixels, and boundary pixels, and then a single non-linear filtering method, such as a sigma filtering method, is applied to each pixel in the digital image. By selecting separate filter parameters for the low detail, high detail, and boundary pixels, the removal of artifacts is improved over prior methods.

  • Patent number: RE41524
    Abstract: An electronic camera captures images representing a variety of subjects and categorizes the image according to subject matter. The camera comprises an image sensor for capturing an image, a converter stage for converting the image into digital image data, and a memory for storing a plurality of categories providing classification of the images by subject. A processor in the camera has the capability of assigning the plurality of categories to the images captured by the camera, with each category providing a subject classification for the images. A user selects one or more categories for a plurality of images prior to capture, and an output image signal is then generated including the digital image data corresponding to a captured image and the particular category selected by the user. The categories can be default identifiers stored in the memory, or can be names, text (i.e., account number), and/or graphics overlays (i.e.
