20110080392 | SYSTEM AND METHOD FOR REINITIALIZING A SCREEN CONTROLLER OF AN ELECTRONIC DISPLAY DEVICE - A system for and method of reinitializing a screen controller of an electronic display device, such as an electrophoretic display, are disclosed. The system may comprise at least one computer processor associated with a screen controller of an electrophoretic display device, where the at least one computer processor may be configured to initialize screen controller registers, loading a waveform into the screen controller of the electrophoretic display device, copying previously stored screen image data stored in direct memory access to current storage of the screen controller; and executing an update process to efficiently reinitialize the screen controller of the electrophoretic display after panel power to the electrophoretic display is provided by at least one power source of the electrophoretic display. | 04-07-2011 |
20110084979 | INTEGRATED ELECTRONIC PAPER DISPLAY CONTROLLER - A system for and method of controlling an electronic display, such as an electrophoretic display, using an integrated electronic paper display controller are disclosed.

20120162396 | Systems and Methods for Converting a 2D Image to a 3D Image - Systems and methods are provided for converting a two dimensional (2D) image for three dimensional (3D) display. In one embodiment, a minimum depth for the 3D image is set to pixels in a bottom portion of the received 2D image. If the 2D image includes an object limiting the maximum image depth, then the maximum depth of the 3D image is set based on a location of the object in the 2D image. If the 2D image does not include an object limiting the maximum image depth, then the maximum depth of the 3D image is set to pixels in a top portion of the 2D image. A continuous depth function is generated from the minimum depth to the maximum depth and is used to generate a stereoscopic image from the 2D image. | 06-28-2012 |
20120194537 | Systems and Methods for Performing Color Adjustment of Pixels on a Color Display - System and methods are provided for performing saturation adjustment of one or more pixels. In one embodiment, an input color value of a pixel is received. The input color value includes an input saturation component. An adjusted color value is extracted from a predetermined look-up table that maps the input color value to the adjusted color value, the adjusted color value having an adjusted saturation component that is different from the input saturation component. The adjusted color value is output. | 08-02-2012 |
20140092276 | Systems and Methods for Camera Image Correction and White Balancing - Systems and methods are provided for calibrating a digital camera. First pixel values of a first calibration image illuminated by white light are captured using a color sensor. A color sensor adjustment matrix is determined based on a comparison of the first pixel values and baseline pixel values associated with the calibration image. Second pixel values of a second calibration image illuminated by a first color temperature light are captured. The second pixel values are adjusted based on the color sensor adjustment matrix, and a first color temperature balance factor is determined based on the adjusted second pixel values, where a white balance adjustment is performed on captured image data based on the first color temperature balance factor. | 04-03-2014 |
20140112595 | LOW-FREQUENCY COMPRESSION OF HIGH DYNAMIC RANGE IMAGES - Methods and apparatuses for adjusting a global dynamic range of an image are described. An image is decomposed into (i) a low spatial frequency component and (ii) a high spatial frequency component. The global dynamic range of the low spatial frequency component is adjusted to produce an adjusted low spatial frequency component. The image is reconstructed with (i) the adjusted low spatial frequency component and (ii) the high spatial frequency component to thereby produce a processed image. | 04-24-2014 |
20140133776 | Systems and Methods for Image Enhancement by Local Tone Curve Mapping - Systems and methods are provided for a method of adjusting a digital image. A low pass filtering is performed on a digital image to remove high frequency data to generate filtered image data. The digital image is divided into a plurality of regions, and a brightness level of a particular region of the digital image is identified using the filtered image data. A transformation curve is selected for the particular region based on the brightness level, and the transformation curve is applied to the particular region to generate adjusted image data for the particular region having adjusted brightness. The adjusted image data is stored in a computer-readable medium. | 05-15-2014 |
