Patent number: 8013871Abstract: Apparatus and methods are provided for editing color profiles. In particular, an output color including a first hue, a first lightness and a first chroma is received, and a first range of lightness values and a first range of chroma values for all output color values in the color profile are determined. A second range of lightness values of output color values in the color profile that have the first hue and the first chroma, and a second range of chroma values of output color values in the color profile that have the first hue and the first lightness are determined. Graphical representations of the first and second ranges of lightness values, and the first and second ranges of chroma values are distinctly displayed on a display device. A user interface is provided that allows a user to create an edited output color including a second hue, a second lightness and a second chroma, and dynamically modify the second range of lightness values and the second range of chroma values based on the edited output color.Type: GrantFiled: November 8, 2006Date of Patent: September 6, 2011Assignee: Electronics for Imaging, Inc.Inventor: Thor A.

Publication number: 20080267501Abstract: Methods and systems for compression of digital images (still or motion sequences) are provided wherein predetermined criteria may be used to identify a plurality of areas of interest in the image, and each area of interest is encoded with a corresponding quality level (Q-factor). In particular, the predetermined criteria may be derived from measurements of where a viewing audience is focusing their gaze (area of interest). In addition, the predetermined criteria may be used to create areas of interest in an image in order to focus an observer's attention to that area. Portions of the image outside of the areas of interest are encoded at a lower quality factor and bit rate. The result is higher compression ratios without adversely affecting a viewer's perception of the overall quality of the image.Type: ApplicationFiled: July 7, 2008Publication date: October 30, 2008Inventors: Richard A. KEENEY, Thor A. Olson

Patent number: 6647149Abstract: Methods and apparatus are provided for securely transmitting and processing digital image data for display. The invention provides for decomposing, compressing, and scrambling digital image data and forwarding the decomposed, compressed and scrambled image data to a destination where the image data is decompressed, re-composed, and descrambled prior to display. In particular, digital image data is scrambled before or after being compressed and is subsequently descrambled after being decompressed and prior to display such that unauthorized use of the image content is prevented. The invention can be used in conjunction with most standard block-based image compression algorithms such as JPEG as well as some types of wavelet transform based systems.Type: GrantFiled: January 3, 2001Date of Patent: November 11, 2003Assignee: Electronics for Imaging, Inc.Inventors: Richard A.

Patent number: 6539323Abstract: The invention provides methods and apparatus for correcting spectral measurements, such as are obtained by a spectrophotometer for measuring color. A single matrix is used that operates on a raw measurement vector (spectrum) to obtain a corrected spectrum. The matrix may embody a transform that minimizes the difference between the corrected spectra and a set of reference spectra. The difference may be characterized by a set of basis function weighting vectors which are then used to build the correction matrix. Correction of high resolution spectra (very long measurement vectors) is thereby allowed, without the large number of measurements that would normally be required. The reference spectra can be calibration data, or measurements made by another instrument which is desired to be simulated.Type: GrantFiled: May 4, 2001Date of Patent: March 25, 2003Assignee: Electronics For Imaging, Inc.Inventor: Thor A.

Patent number: 6381036Abstract: A method is provided for determining colorant levels required by a printer to match a target color. A set of candidate colors is generated on a computer and printed on the printer. Color neighbors in the candidate color sets are calculated based on the colorants of the particular printer being used, but are presented to the user according to their human-natural organization by hue, lightness and saturation. One or more further sets of candidate colors are generated on the computer in response to user input indicative of a correlation between a color in a most recent printed set of candidate colors and the target color. The user then chooses a further set of candidate colors to be printed. The steps of generating and printing further sets of candidate colors are repeated, if necessary, until a selected color in the most recent printed set of candidate colors acceptably matches the target color.Type: GrantFiled: June 7, 1999Date of Patent: April 30, 2002Assignee: Electronics for Imaging, Inc.Inventor: Thor A.

Patent number: 6112665Abstract: A blank is provided for producing color swatches on a color printer or photocopier. A sheet adapted to be fed through the printer or photocopier contains a first set of perforations defining the perimeter of a swatch card. A second set of perforations disposed within the perimeter of the swatch card defines a plurality of openings. The openings are punched out, preferably after color swatches have been printed on the swatch card, in order to enable the viewing of a sample color through the opening for comparison with the color swatches. A third set of perforations is provided in a corner of the swatch card to enable a plurality of swatch cards to be assembled into a reference deck by passing a fastener through holes formed via the third set of perforations. Each sheet can have a plurality of swatch cards laid out therein, with each swatch card containing a plurality of color swatches.Type: GrantFiled: March 4, 1999Date of Patent: September 5, 2000Assignee: Electronics For Imaging, Inc.Inventors: James R.

Patent number: 5389985Abstract: An imaging system such as an image recorder or scanner is provided with a rearview cathode ray tube. A transparent viewport of optical quality is provided along an optical axis of the CRT which is perpendicular to the CRT faceplate and generally centered with respect to the image area. The electron beam used for scanning the images is placed off-axis with respect to the CRT screen. A deflection control system compensates for spherical distortion and for the keystone effect that results from the off-axis placement of the electron gun. The structure of the present invention eliminates halation, thereby improving the dynamic range and contrast achievable for imaging and/or scanning purposes. The phosphor layer used in the CRT is made substantially thicker than in conventional CRTs, thereby reducing blemishes and improving uniformity, resolution and light output. The partial sharing of electron beam and optical paths enables more compact imaging and scanning systems to be provided.Type: GrantFiled: November 15, 1993Date of Patent: February 14, 1995Assignee: Management Graphics, Inc.Inventors: Thor A.
