  • Patent number: 9936129
    Abstract: Techniques are disclosed for generating a high resolution image from a plurality of images captured from a plurality of sensors. The pixels in one sensor have at least one of different size, shape, or orientation than pixels in another sensor. The difference in size, shape, or orientation of the pixels and the interconnection of pixels on respective sensors provides a high level of certainty that there will be sufficient difference in the captured images, with limited loss in image content, to generate a relatively high resolution image from the images captured by the respective sensors.

  • Publication number: 20160103266
    Abstract: This disclosure provides systems, methods and apparatus for light-guiding layers including asymmetrical light-turning features. In one aspect, the asymmetrical light-turning features may include a leading edge oriented at an angle which turns light out of the light-guiding layer, and a near-vertical trailing edge which reduces light leakage from the light-guiding layer. In another aspect, the asymmetrical light-turning features of the light-guiding layer may be oriented in the same or similar direction, and may be distributed with decreasing density adjacent a light source to provide more even illumination.

  • Publication number: 20160027410
    Abstract: Various display device implementations disclosed herein include display drivers with enhanced capabilities. In some implementations a display driver may be capable of updating a display while a central processing unit (CPU) is switched off or operating in a sleep mode. Some such display drivers may include a display driver clock and a display driver memory. The display driver may be capable of receiving image data from the CPU, including image data for display updates, and storing received image data in the display driver memory. The display driver may be capable of updating the display with stored image data at times indicated by the display driver clock. Some display drivers may include a graphics processing unit capable of generating image data for updates of the display. In some such implementations, the graphics processing unit may be capable of dithering image data.

  • Patent number: 9218538
    Abstract: Methods and systems for detecting an object borderline. A first image with respect to the object can be captured by an image-capturing unit without a flash light and borderlines of the object can be detected. If the detection is successful, the detected borderlines can be outputted. Otherwise, a second image with respect to the object can be captured by the image-capturing unit by applying a flash light and the borderlines can be detected in the image. A geometric transformation between the two images can then be estimated. Finally, the border lines in the first image can be determined by transforming the borderlines detected in the second image. Such an approach effectively detects the appliance borderlines and avoids artifacts caused by applying flash.

  • Publication number: 20150358504
    Abstract: The systems and methods described herein may be used to optimize vector error diffusion for displaying color images on a display device. Vector error diffusion passes a residual vector error from one pixel on to its neighboring pixels with varying weights. The direction and weight of error diffusion can be defined by a vector error diffusion filter. Using a vector error diffusion filter with a limited number of taps allows an a priori determination of which pixel vector is dependent on which pixel vector error at what times. Based on such dependency determination, vector error diffusion calculation for multiple pixels can be scheduled to optimize computation time while preserving the dependency. The scheduled vector error diffusion calculation can further be implemented in virtual pipeline with multiple stages to balance computation load and utilize hardware resource efficiently.

  • Patent number: 9183619
    Abstract: When restoring a scanned halftone image of a damaged document, parameters of the halftone structure (geometry) are estimated, as is an intended contone gray level for damaged portions of the image. Locations of halftone cell tiles in the scanned image are determined based on the halftone structure, and a halftone profile model is generated using the estimated halftone parameters and contone information. Image segments are aligned using global features for coarse alignment and halftone structure for fine alignment, such as in cases where the scanned halftone image contains unconnected fragments. Missing parts of the damaged document image are filled in using the halftone profile model and estimated contone values.

  • Patent number: 8970910
    Abstract: As set forth herein, computer-implemented methods and systems facilitate watermarking documents and/or images using 2nd generation stochastic halftoning. The watermark is used to spatially vary the gray level at which a frequency modulation-to-amplitude modulation transition occurs. The encoding algorithm uses as inputs a contone image and a watermark. The visibility of the watermark is controlled by the magnitude of the difference between the AM-to-FM transition threshold values.
