  • Publication number: 20110097011
    Abstract: Visual elements of a first image are changed in accordance with an image editing process to produce an edited high-resolution image and visual elements of a second image are modified in accordance with an emulator process to produce a modified low-resolution image. The emulator process produces the modified low-resolution image with visual changes relative to the second image that mimic perceived visual changes made to the visual elements of the first image by the image editing process to produce the edited high-resolution image. The emulator process is built from a set of one or more image enhancement processes in accordance with an optimization process.

  • Publication number: 20100275152
    Abstract: A candidate layout of frames on a page is ascertained, where the frames define respective size dimensions and positions of respective views of the graphic objects (including at least one block of text) on the page. If the target size dimensions are not accommodated by the size dimensions of the frame of the text block presentation, the candidate layout is modified by changing the size dimensions of the frame of the text block presentation to accommodate the target size dimensions and adjusting the size dimensions of the other frames in the candidate layout based on the changed size dimensions of the frame of the text block presentation. Also, different layouts of the frames on a page are determined from a different respective set of aspect ratios and nominal sizes subject to a set of layout constraints.

  • Publication number: 20100243899
    Abstract: A solid state imaging device includes an array of active pixels and an infrared cut filter formed over the sensor. Optionally, a slot in the infrared cut filter allows infrared illumination to reach the sensor to be detected by pixels covered by a visually opaque filter and surrounded by pixels of special types that limit charge leakage and enable high dynamic range sensing of infrared illumination. A ratio of average infrared signal to average brightness indicates an amount of infrared illumination reaching the imaging device.

    Abstract: In a method for dynamically scaling an original background layout having at least one element, an instruction to employ the original background layout in a new page that differs in at least one of size and aspect ratio from at least one of the size and aspect ratio of the original background layout is received. In addition, a type and a position of the at least one element is identified and one or more constraints are applied on at least one characteristic of the at least one element to modify the at least one characteristic of the at least one element for inclusion in the new page, in which the one or more constraints are based upon the type and position of the at least one element.

  • Publication number: 20100199227
    Abstract: A user interface that includes a catalog area, a collage mock-up area, and a mode select interface control operable to select an operational state of the user interface is displayed. Thumbnails of respective images are shown in the catalog area. A layout of a subset of the images is presented in the collage mock-up area. In response to the receipt of a user input gesture and a determination that the user interface is in a first operational state, a first action type is performed based on the type of the received user input gesture and the object type of the target object. In response to the receipt of the user input gesture and a determination that the user interface is in a second operational state, a second action type is performed based on the type of the received user input gesture and the object type of the target object.

Each correlation window includes a primary encoding marker in form of vertical line segment and a set of secondary encoding markers in form of diagonal line segments, at least one diagonal line segment intersecting the vertical line segment at an intersection angle. Spacing of the diagonal line segments encodes the X-axis position of the input device relative to the encoding pad. Intersection angle encodes the Y-axis position of the input device relative to the encoding pad. Angle of the primary encoding marker vertical line segment within the frame of the captured image encodes the angular orientation of the input device relative to the axes of the encoded pad.

  • Patent number: 7352892
    Abstract: Reconstructing the shape of the surface of an object in greater than two dimensions is performed using a noise-tolerant reconstruction process and/or a multi-resolution reconstruction process. The noise-tolerant reconstruction process can be a Bayesian reconstruction process that adds noise information representing the noise distribution in optical image(s) of the object to surface gradient information estimated from the images to determine surface height information that defines the shape of the surface of the object in greater than two dimensions. In the multi-resolution reconstruction process, for each resolution of the image, the surface gradient information is estimated and the surface height information is calculated using the estimated surface gradient information. To obtain the final surface height map, the surface height information from each resolution is combined to reconstruct the shape of the surface of the object in greater than two dimensions.

  • Patent number: 7292024
    Abstract: Defect mitigation in display panels. Defects in a display panel are mapped, and the defect information is associated with the display system or associated with the panel. During panel operation, the values of pixels neighboring defective pixels are altered to minimize their visibility to the observer. In a first model, luminance error caused by a defect is compensated by adjust neighboring pixels. In a second model, Error in luminance and one of the two chrominance channels is compensated by adjusting neighboring pixels. The defect mitigation methods seek to shift the errors introduced by defective pixels into high spatial frequency elements and chromatic elements, which the human eye is not sensitive to.

  • Patent number: 7283164
    Abstract: A bad pixel correction (BPC) algorithm that can be implemented on the image sensor chip is provided for detecting and correcting defective pixels in a digital color image sensor. Gradients of neighboring pixels in at least one other color plane than the color plane of a current pixel and a range of sensor values from neighboring pixels in the same color plane as the current pixel are determined. If the sensor value of the current pixel is outside of the range by a threshold amount that is calculated using one or more of the gradients, the current pixel is determined to be a defective pixel, and replaced using the sensor values of the neighboring pixels in the same color plane.

  • Patent number: 7278048
    Abstract: A method and system for improving the reliability of a system, such as a software system, is disclosed. “Service measurements” that are routinely measured and monitored in connection with the operation of systems (e.g., QOS (Quality Of Service) measurements) are utilized in the reliability architecture of the system. Service measurements include a number of alternative data types, such as transactions completed, messages received, messages sent, calls completed, bytes transmitted, jobs processed, etc. Any operations of the system that are typically monitored for other purposes can be utilized in the reliability architecture of the present invention. Most systems track these types of statistics as, for example, part of their billing procedures or part of their performance bench-marking or QOS processes.

  • Publication number: 20070226546
    Abstract: The invention includes a method for determining a software reliability metric, including obtaining testing defect data, obtaining test case data, determining testing exposure time data using the test case data, and computing the software reliability metric using testing defect data and testing exposure time data. The defect data includes software defect records. The test case data includes test case execution time data. A testing results profile is determined using testing defect data and testing exposure time data. A software reliability model is selected according to the testing results profile. A testing defect rate and a number of residual defects are determined by using the software reliability model and the testing results profile. A testing software failure rate is determined using the testing defect rate and the number of residual defects. A field software availability metric is determined using the field software failure rate determined using the testing software failure rate.
