20210127102 · 2021-04-29 ·

A tangible, non-transitory machine-readable medium includes machine-readable instructions that, when executed, cause processing circuitry to receive a signal indicative of high dynamic range content. The signal includes 1) a first portion that forms a first percentage of the signal and is associated with a first brightness range and 2) a second portion that forms a second percentage of the signal associated with a second brightness range. The instructions, when executed, are also configured to cause the processing circuitry to produce an adjusted signal to represent the signal such that a graphical representation of the adjusted signal includes an area corresponding to the first portion of the signal that is expanded relative to a graphical representation of the first portion of the signal. Furthermore, the instructions, when executed, are configured to cause the processing circuitry to cause display of a graphical representation of the adjusted signal.

Organic light emitting diode display compensation tool

A portable information handling system integrated organic light emitting diode (OLED) display presents a compensation image having pixels illuminated at predetermined color and luminance settings. The compensation image is captured by a external camera as a calibration image and analyzed to compare pixel color and luminance provided by the OLED display with expected color and luminance to determine pixel compensation values that correct the OLED display for presentation of a uniform visual image that reproduces an intended visual image when the compensation values are applied at presentation of visual images by the OLED display.

Method and apparatus for compensating for color separation of image in a laser projector-based holographic head-up 3 display

An apparatus and method for compensating for color separation of an image in a holographic head-up display (HUD), caused by a change in characteristics such as a temperature or wavelength of a laser projector. An apparatus (200) for compensating for color separation of an image in a HUD includes a GPU (100); a video signal inputter (110); a temperature sensor (120); a controller (130); a memory (135); a panel driving unit (140) for outputting an image to a panel (160); a laser diode driving unit (150) for driving R, G, and B laser diodes (151), (152), and (153); a lens (70), and a screen (180). Accordingly, an image, the quality of which is degraded due to color separation of an image, may be improved.

Systems and methods for calibrating an array camera are disclosed. Systems and methods for calibrating an array camera in accordance with embodiments of this invention include the capturing of an image of a test pattern with the array camera such that each imaging component in the array camera captures an image of the test pattern. The image of the test pattern captured by a reference imaging component is then used to derive calibration information for the reference component. A corrected image of the test pattern for the reference component is then generated from the calibration information and the image of the test pattern captured by the reference imaging component. The corrected image is then used with the images captured by each of the associate imaging components associated with the reference component to generate calibration information for the associate imaging components.

System and Method for Focusing Color Schlieren Diagnostics

Embodiments of the present application are directed toward a focusing Schlieren technique that is capable of adding color-coded directional information to the visualization of density gradients. Other advantages of the technique can include that it does not require manual calibration, has a simple design and is sensitive enough to be used in compact experimental setups. Certain embodiments include the use of a color-coded source image that replaces the conventional source grid. The technique may benefit from a computer-controlled digital background, which is used for both illumination and display of color-coded source images.
