  • Patent number: 10281644
    Abstract: Laboratory optical imaging systems for fluorescence and bioluminescence use a sensitive charge-coupled device (CCD) camera to produce quantitative measurements of very low light intensity, detecting signals from specimens labeled with optical fluorophores or luminescent emitters. Commercially available systems typically provide quantitative measurements of light output, in units of radiance (photons s?1 cm?2 SR?1) or intensity (photons s?1 cm?2). We describe a quality assurance system for low-light imagers, based on an LED-illuminated thin-film transistor (TFT) liquid crystal display module. The light intensity is controlled by pulse-width modulation of the backlight, producing intensity values ranging from 1×106 photons s?1 cm?2 to 4×1013 photons s?1 cm?2. The lowest light intensity values are produced by very short backlight pulses (i.e. approximately 10 ?s), repeated every 300 s.

A laser point-scans the surface of the object with light spots, which are detected by a pixel array in the image sensor to generate the 3D depth profile of the object using triangulation. Each row of pixels in the pixel array forms an epipolar line of the corresponding laser scan line. Timestamping provides a correspondence between the pixel location of a captured light spot and the respective scan angle of the laser to remove any ambiguity in triangulation. An Analog-to-Digital Converter (ADC) in the image sensor operates as a Time-to-Digital (TDC) converter to generate timestamps. A timestamp calibration circuit is provided on-board to record the propagation delay of each column of pixels in the pixel array and to provide necessary corrections to the timestamp values generated during 3D depth measurements.

In one pixel, a pixel electrode including both of a region where incident light through a liquid crystal layer is reflected and a transmissive region is provided, and image display can be performed in both modes: the reflective mode where external light is used as an illumination light source; and the transmissive mode where the backlight is used as an illumination light source. When there is external light with insufficient brightness, that is, in a dim environment, the backlight emits weak light and an image is displayed in the reflective mode, whereby image display can be performed.

  • Patent number: 10235914
    Abstract: A camera colorimeter system simultaneously lights up one or more pixel units on a display panel, each pixel unit including colored subpixels, for characterization of the display panel. The system includes optical elements that directs the light emitted by the simultaneously lit one or more pixel units to a filter and a corresponding imaging device. Each filter is configured to block wavelengths of light other than predetermined range of wavelengths, thereby ensuring that each imaging device captures a filtered spectrum of light that originates from subpixels of the same color. Using the filtered spectrum, the system reconstructs the full spectrum of light, which can subsequently be used to regenerate the display characteristics of each pixel unit (and corresponding colored subpixels). Thus, the camera colorimeter system can characterize a display panel in significantly less time as compared to conventional systems and methods.

  • Patent number: 10235962
    Abstract: The present disclosure provides devices and techniques for dynamically adjusting the bias voltage (V) levels (e.g., low level gate voltage (VGL) and high level gate voltage (VGH)) for display screens made with thin-film transistor (TFT) technology based on a display run time. Thus, as the positive bias temperature stress for the TFTs increases over the course of the display lifetime, features of the present disclosure adjust the bias voltage levels to maintain operation margin (e.g., the ratio between the high level gate voltage (VGH) value and the voltage value which the display can maintain with normal operation). By dynamically adjusting the bias voltage levels, the TFT displays of the present disclosure consume lower power than their conventional counterparts and improve the lifetime of the display itself.

  • Patent number: 10237728
    Abstract: A system for designating a wireless communication device (WCD), a method of identifying a WCD, a system for identifying users of WCD in local zones, and machine-readable carriers enabling implementation of the aforementioned methods are proposed. The method identifying WCD includes steps of accepting network packets containing device identifiers (DIs), determining DIs, checking whether the DI is stored in a database associated with the system. If it's not stored in the database—initiating an application pre-installed on the WCD that sends a registration request to the system, during which DI is inputted into the database along with an application identifier (AI) associated with the DI, and acting as an address to which push-notifications corresponding to the WCD are sent. If DI is stored in the database, AI is retrieved therefrom. The proposed methods and systems provide for a possibility of identifying WCDs together with their geolocation in local zones.

  • Patent number: 10229339
    Abstract: The technology disclosed relates to identifying an object in a field of view of a camera. In particular, it relates to identifying a display in the field of view of the camera. This is achieved by monitoring a space including acquiring a series of image frames of the space using the camera and detecting one or more light sources in the series of image frames. Further, one or more frequencies of periodic intensity or brightness variations, also referred to as ‘refresh rate’, of light emitted from the light sources is measured. Based on the one or more frequencies of periodic intensity variations of light emitted from the light sources, at least one display that includes the light sources is identified.

  • Patent number: 10224074
    Abstract: A method includes receiving a first digital video signal having frames at a first frame rate. A respective frame of the first digital video signal is then replicated multiple times to produce a series of replicated frames for inclusion in a second digital video signal have a second frame rate greater that the first frame rate. For at least some of the pixel data defining pixels in at least one of the replicated frames, the method includes randomly modifying the respective pixel data. The random modification of pixel data for a respective pixel in a respective replicated frame results in a modified replicated frame which is included in the second digital video signal.
