Patent number: 9319729Abstract: Techniques and tools for high accuracy position calculation for picture resizing in applications such as spatially-scalable video coding and decoding are described. In one aspect, resampling of a video picture is performed according to a resampling scale factor. The resampling comprises computation of a sample value at a position i,j in a resampled array. The computation includes computing a derived horizontal or vertical sub-sample position x or y in a manner that involves approximating a value in part by multiplying a 2n value by an inverse (approximate or exact) of the upsampling scale factor. The approximating can be a rounding or some other kind of approximating, such as a ceiling or floor function that approximates to a nearby integer. The sample value is interpolated using a filter.Type: GrantFiled: May 30, 2014Date of Patent: April 19, 2016Assignee: Microsoft Technology Licensing, LLCInventor: Gary J. Sullivan

The adjacent pixel adding unit (9) adds the values of the pixel divisions protruding from the pre-shift range of the array of pixel divisions to the column of contracted pixels of the pixel adjacent in the protruding direction. The first mask generation unit (11) generates mask data indicating the fill according to the array of contracted pixels.Type: GrantFiled: November 4, 2009Date of Patent: May 27, 2014Assignee: NEC System Technologies, Ltd.Inventor: Kenji Akiyoshi

Patent number: 8723868Abstract: Systems and methods for displaying digitized waveform data on a pixilated screen are provided. Certain methods include retrieving waveform data that exists as a plurality of sequential samples in a buffer. A first sample is associated with a first point of a pixilated screen. A second sample that follows the first sample is associated with a second point of the screen. A boundary of a rectangular line segment connecting the points is determined. For each pixel of the pixilated screen that has any portion inside the boundary of the rectangular line segment, a number of subpixels within the pixel that have any portion inside the boundary of the rectangular line segment is determined and that number of subpixels is correlated with an intensity value that is then associated with the pixel. Waveform data is displayed by painting pixels of the screen with the associated intensity values.Type: GrantFiled: September 23, 2010Date of Patent: May 13, 2014Assignee: General Electric CompanyInventor: Aaron James Hill

Patent number: 8717378Abstract: A cubic, or other polynomial, approximation to a panel's gamma function. Embodiments contemplate a display system configured to apply a panel gamma function that is a third-order polynomial function, as well as its substantial inverse. This third order function is often easier to implement, and yields lower gate count than current power law gamma functions.Type: GrantFiled: March 29, 2011Date of Patent: May 6, 2014Assignee: Samsung Display Co., Ltd.Inventor: Anthony Botzas

Publication number: 20140118389Abstract: An anti-aliasing font character on a monitor is prevented from being erroneously judged as an image region. The pixel of interest and four pixels each preceding and following the pixel of interest (a total of nine pixels) are extracted (S3). The largest of the values of the sub-pixels of each of the nine pixels extracted is determined as the representative value of each pixel (step S5). The nine representative values are represented as a histogram and referred to as H0, H1, H2, and the like in the descending order of the frequency in the distribution (S7). Whether Formula (1) below is satisfied is determined (S9). H0+H1+H2<TH . . . (1) If Formula (1) is satisfied, the pixel of interest is judged as a non-character-region pixel; if not, the pixel of interest is judged as a character-region pixel (S11, S13).Type: ApplicationFiled: September 9, 2011Publication date: May 1, 2014Applicant: EIZO CorporationInventors: Haifeng Chen, Masashi Nakao

Patent number: 8711170Abstract: A video display pipe used for processing pixels of video and/or image frames may include edge Alpha registers for storing edge Alpha values corresponding to the edges of an image to be translated across a display screen. The edge Alpha values may be specified based on the fractional pixel value by which the image is to be moved in the current frame. The video pipe may copy the column and row of pixels that are in the direction of travel, and may apply the edge Alpha values to the copied column and row. The edge Alpha values may control blending of the additional column and row of the translated image with the adjacent pixels in the original frame, providing the effect of the partial pixel movement, simulating a sub-pixel rate of movement.Type: GrantFiled: February 14, 2011Date of Patent: April 29, 2014Assignee: Apple Inc.Inventors: Joseph P. Bratt, Peter F. Holland, Gokhan Avkarogullari

Patent number: 8711184Abstract: A method of generating an image of a scalable graphical object for reproduction on a display device is disclosed. The method provides a pixel map and a scaling factor, the map being a representation of at least of portion of the image with each pixel of the map corresponding to a pixel of the image and having a corresponding pixel coverage representation. The method, for at least one pixel in the map, identifies the pixel coverage representation associated with the pixel, and determines a pixel coverage value for the pixel using the pixel coverage representation and the scaling factor. The method then renders the scalable graphical object using the determined pixel coverage value for the pixel on the display device.Type: GrantFiled: April 19, 2010Date of Patent: April 29, 2014Assignee: Canon Kabushiki KaishaInventor: Gregory John Marr

Patent number: 8704847Abstract: Display systems and image processing methods process pre-subpixel rendered images embedded in input color image data. The display systems include a pre-subpixel rendered (P-SPR) image detector that detects locations of a marking code that marks the portion of the input data that has been pre-subpixel rendered and which is ready for direct display. Several display system embodiments comprise first and second image data paths; the input data that requires subpixel rendering proceeds along the first path while the P-SPR image data proceeds along the second path. Another display system embodiment processes the combined input and P-SPR data along a single data path. Techniques for marking and detecting P-SPR image data using two distinct marking codes are presented in the context of the subpixel layout of the display. Techniques for using P-SPR data to display high-quality graphical symbols (e.g., font glyphs) are suitable for small, low-cost display devices.Type: GrantFiled: April 4, 2006Date of Patent: April 22, 2014Assignee: Samsung Display Co., Ltd.Inventors: Michael Francis Higgins, Seok Jin Han, Candice Hellen Brown Elliott

Patent number: 8703037Abstract: A solid imaging apparatus and method employing sub-pixel shifting in multiple exposures of the digitally light projected image of a cross-section of a three-dimensional object on a solidifiable liquid medium. The multiple exposures provide increased resolution, preserving image features in a three-dimensional object and smoothing out rough or uneven edges that would otherwise be occur using digital light projectors that are limited by the number of pixels in an image projected over the size of the image. Algorithms are used to select pixels to be illuminated within the boundary of each image projected in the cross-section being exposed.Type: GrantFiled: June 9, 2010Date of Patent: April 22, 2014Assignee: 3D Systems, Inc.Inventors: Charles W.
