  • Patent number: 10032096
    Abstract: A terminal uses a web application to control a printer on a network. The web application includes an API that permits the terminal to send instruction and inquiries to the printer over the network. The terminal submits, to the API, the printer's IP address and instructions for defining a print document or printer commands. The API then sends the print document or printer commands to the printer in accordance with the IP address. In this manner, the terminal can request status updates without sending a print job to the printer. The terminal sets the printer's ID address, identifies a type of status event inquiry, and submits the inquiry to receive the printer's current status related to the identified status event. To submit a print job, the terminal creates a print document using the API, sets the printer's ID address, and sends the print document as a print job to be printed.

  • Patent number: 10033939
    Abstract: A method and apparatus provide automatic stage scene detection. A first image of a scene can be captured using a luminance for automatic exposure control. A brightness contrast between a center region of the first image and areas surrounding the center region of the first image can be calculated. A brightness value can be ascertained for the entire first image. Whether the luminance of the first image should be adjusted can be determined based on the brightness contrast being greater than a contrast threshold and the brightness value for the entire first image being less than a brightness value threshold. The luminance for the automatic exposure control can be adjusted for correct exposure of the center region of the first image in response to determining the luminance of the first image should be adjusted. A second image of the scene can be captured based on automatic exposure control using the adjusted luminance.

  • Patent number: 10028022
    Abstract: A media effects engine on a computer device applies one or more effects to an input media stream. A performance monitor monitors a performance metric associated with playing the input media stream and reduces a quality parameter associated with the effect upon detecting a drop in the performance metric below a target metric. The quality parameter manages a tradeoff between a quality of effect and an amount of hardware resources consumed to produce the effect. Thus, the effect can be adjusted to meet the capabilities of the computer device.

  • Patent number: 10013907
    Abstract: A method and system for programming, calibrating and driving a light emitting device display, and for operating a display at a constant luminance even as some of the pixels in the display are degraded over time. The system may include extracting a time dependent parameter of a pixel for calibration. Each pixel in the display is configured to emit light when a voltage is supplied to the pixel's driving circuit, which causes a current to flow through a light emitting element. Degraded pixels are compensated by supplying their respective driving circuits with greater voltages. The display data is scaled by a compression factor less than one to reserve some voltage levels for compensating degraded pixels. As pixels become more degraded, and require additional compensation, the compression factor is decreased to reserve additional voltage levels for use in compensation.

    Abstract: A data conversion server reduces a data amount of a path that constitutes drawing data. The data conversion server adds information used to adjust a scale of the drawing data to the drawing data, wherein the information is obtained based on a length of the path before the data amount is reduced. For example, in a case of data in the SVG format, path length information before the data amount is reduced is set to an attribute (pathLength) as the information used to adjust the scale.

  • Patent number: 9928770
    Abstract: A method for adjusting a display effect and an electronic apparatus that includes a frame body, a fixing device, and a functional main body section. The functional main body section includes a display device disposed in the frame body. When a user views a first display content in the first display region in a first interactive mode, a light beam emitted by the display device is incident upon the user's eyes so that the user perceives a first perception picture. The display parameter of the display device is adjusted by obtaining the adjustment parameter for instructing to adjust the display effect of the first perception picture, and thereby generating the corresponding control signal, so that a current display effect of the first perception picture is different from a display effect of the first perception picture before the adjustment.

  • Patent number: 9916640
    Abstract: Techniques for automatically removing slivers from orthomosaics. First, slivers may be identified, which may be based upon user-configurable characteristics such as width and length. Second, slivers may be replaced with portions of another image, such as an older image. Third, boundary slivers may optionally be removed. Fourth, remaining boundary or interior slivers can be inflated by expanding the sliver until it is no longer a sliver, which may include replacing a portion of an adjacent image portion with older imagery.

  • Patent number: 9918057
    Abstract: A method, apparatus and system of projecting text characters onto a textured document are described. The method comprises determining, from a captured image of the textured surface, a measure of the texture on the surface for a region of the textured surface over which the text characters are to be projected; selecting, based on a function of the determined measure, a glyph set, each glyph in the glyph set having visually contrasting inner and outer portions, the outer portion being sized proportionally to the inner portion according to the determined measure; and projecting the text characters onto the textured surface on of region using the selected glyph set.

  • Patent number: 9916674
    Abstract: One embodiment of the present invention sets forth a technique for improving path rendering on computer systems with an available graphics processing unit. The technique involves reducing complex path objects to simpler geometric objects suitable for rendering on a graphics processing unit. The process involves a central processing unit “baking” a set of complex path rendering objects to generate a set of simpler graphics objects. A graphics processing unit then renders the simpler graphics objects. This division of processing load can advantageously yield higher overall rendering performance.

  • Patent number: 9898976
    Abstract: The color shift compensation method comprises: receiving target input gray scale data of a target sub pixel dot in a present line, and acquiring previous output gray scale data of a sub pixel dot of the previous line in the same display data line of the target sub pixel dot, and then, implementing digital to analog conversion to the target output gray scale data of the target sub pixel dot simultaneously corresponding to the target input gray scale data and the previous output gray scale data with combination of the target relationship table to acquire the target voltage of the target sub pixel dot, and ultimately, adjusting a color displayed by a target pixel where the target sub pixel dot is. With the present invention, the color shift issue due to the resistance difference of the fan section can be solved to promote the display effect.

  • Patent number: 9892494
    Abstract: Methods, devices and computer readable instructions to generate region-of-interest (ROI) tone curves are disclosed. One method includes obtaining a statistic for an entire image such as, for example, a luminance statistic. The same statistic may then be found for a specified ROI of the image. A weighted combination of the statistic of the entire image and the statistic of the ROI yields a combined statistic which may then be converted to a ROI-biased tone curve. The weight used to combine the two statistics may be selected to emphasize or de-emphasize the role of the ROI's statistic in the final tone curve.
