    Abstract: Techniques for calibrating cameras and displays are disclosed. An image of a target is captured using a camera. The target includes a tessellation having a repeated structure of tiles. The target further includes unique patterns superimposed onto the tessellation. Matrices are formed based on pixel intensities within the captured image. Each of the matrices includes values each corresponding to the pixel intensities within one of the tiles. The matrices are convolved with kernels to generate intensity maps. Each of the kernels is generated based on a corresponding unique pattern of the unique patterns. An extrema value is identified in each of the intensity maps. A location of each of the unique patterns within the image is determined based on the extrema value for each of the intensity maps. A device calibration is performed using the location of each of the unique patterns.

  • Patent number: 11554717
    Abstract: A vehicular vision system includes a camera disposed at a vehicle and operable to capture multiple frames of image data during a driving maneuver of the vehicle. A control includes an image processor that processes frames of captured image data to determine feature points in an image frame when the vehicle is operated within a first range of steering angles, and to determine motion trajectories of those feature points in subsequent image frames for the respective range of steering angles. The control determines a horizon line based on the determined motion trajectories. Responsive to determination that the determined horizon line is non-parallel to the horizontal axis of the image plane, at least one of pitch, roll or yaw of the camera is adjusted. Image data captured by the camera is processed at the control for object detection.

  • Patent number: 9059690
    Abstract: The contribution of noise to digitally sampled signals is reduced using a statistical processor and a slope limiter. The statistical processor determines an average value (mean and/or standard deviation) of the filtered signal which is used to determine a slope limit corresponding to an expected maximum first derivative value of a target signal frequency. This slope limit is applied to constrain the output of an analog to digital converter, to prevent the output of the analog to digital converter from exceeding this maximum rate of rise or fall. By constraining the output of the analog to digital converter, it is possible to digitally sample analog signals without first utilizing an anti-aliasing filter, since the post processing of the digitally sampled signals limits the contribution of the higher frequency components of the signal to thereby enable a fully digital sampling and filtering circuit to be provided for receiving signals.

  • Patent number: 8866914
    Abstract: Provided is a pattern position detection method that allows detecting positions of patterns used for alignment with high accuracy. According to the pattern position detection method of the present invention, patterns are displayed on a liquid crystal panel (2) and captured by a camera (3). A black image is displayed on the liquid crystal panel (2) and captured by the camera (3) using a shutter speed or an f-number used when capturing the patterns. Based on a difference between a captured image of the patterns and a captured image of the black image, positions of images of the patterns on an imaging surface of the camera (3) are detected.

  • Publication number: 20140300751
    Abstract: A system for quickly aligning a test optic with various components of an optical metrology tool. A collimated target is presented to a beamsplitting reference surface located on a positioning system for holding and manipulating the test optic. Video images of the target and its reflection from the reference surface are displayed for analysis and visualization so that any tilt between the reference surface and the optical axis of the collimated beam can be removed to align the test optic. After alignment, the video based system is used to quickly measure and display in real-time a variety of performance characteristics of optical components such as lenses. The metrology system is under the control of a computer which uses a windowing software program to provide the user with a graphical user interface by which the various components of the system and test lenses may be aligned and characterized.

  • Publication number: 20140293068
    Abstract: According to our invention, linked operation between a monitor apparatus for displaying images, and a set-top box for transmitting image signals to the monitor apparatus via a required interface, can be achieved properly, even if both units are constructed in casings separate from each other. The monitor apparatus uses a CEC line to transmit a CEC vendor command including at least a code associated with unit information, and the set-top box apparatus transmits the CEC vendor command including at least the code associated with the unit information. Upon receiving the vendor command from the set-top box apparatus, the monitor apparatus switches to the linked operation with the set-top box.

  • Patent number: 8842185
    Abstract: Systems and methods for evaluating video quality of HDMI data are provided. In one example an HDMI video quality evaluator controls a video device to render a test pattern and encode the pattern into HDMI. The video device is controlled to transmit the HDMI formatted pattern from an output port to an input port on the device, capture a frame of the pattern, and transmit the frame to the quality evaluator. The quality evaluator compares rendered pixels in the frame to test pixels in the test pattern to identify video quality errors. Errors that exceed a threshold are identified, and a test result is outputted that includes errors exceeding the threshold.

  • Patent number: 8842184
    Abstract: Accurately estimating the image quality of video is still difficult, especially when there is no reference video available. A method for determining a quality measure for a video image comprises selecting a measuring point, such as a MB, determining a context area around the measuring point, calculating a variance of pixel values in the context area, calculating a variance of pixel values in the measuring point, calculating a relation between the two variances of pixel values, and averaging said relations for a plurality of measuring points, wherein a quality measure for a video image is obtained.

  • Patent number: 8797461
    Abstract: A screen time control device includes a source interface for receiving a video signal, a processor connected to the video source interface for overlaying the video signal with a translucent signal to produce an overlaid video signal, and a device interface connected to the processor for receiving the overlaid video signal and providing the overlaid video signal to the display device. The processor substitutes the translucent signal in the overlaid video signal with a parental signal, where the parental signal can be a substantially opaque overlay signal that masks an image on the screen of the display device to prohibit viewing of the screen, a textual message, or a combination of both.
