Patent number: 10275932Abstract: Embodiments of the invention relate to a display operable in 2D and 3D display modes. Methods and apparatus are provided for adjusting the colors and brightness of the image data and/or intensity of the display backlight based on the current display mode and/or color-grading of the image data. For example, when switching to a 3D display mode a color mapping may be performed on left and right eye image data to increase color saturation in particular regions, and/or the backlight intensity may be increased in particular regions to compensate for lower light levels in 3D display mode.Type: GrantFiled: March 4, 2015Date of Patent: April 30, 2019Assignee: Dolby Laboratories Licensing CorporationInventors: Eric Kozak, Robin Atkins

Patent number: 10114838Abstract: Scene-referred metadata comprising correspondence relationships between coded values used in generated images and reference values defined independent of any specific image may be provided as a part of image metadata for the generated images. Downstream image processing devices or image rendering devices may use the scene-referred metadata to perform image processing or rendering operations. When coded values of input images are altered in corresponding output images, the scene-referred metadata may be updated with new coded values used in the output images. Reference values refer to reference color values or reference gray levels. Coded values refer to color values or gray levels coded in pixels or sub-pixels of one or more images.Type: GrantFiled: April 16, 2013Date of Patent: October 30, 2018Assignee: Dolby Laboratories Licensing CorporationInventors: Arshad Ali, Peter Longhurst, Eric Kozak

Patent number: 9711096Abstract: Several embodiments of display systems that use narrowband emitters are disclosed herein. In one embodiment, a display system comprises, for at least one primary color, a plurality of narrowband emitters distributed around the primary color point. The plurality of narrowband emitters provides a more regular power vs. spectral distribution in a desired band of frequencies.Type: GrantFiled: August 3, 2015Date of Patent: July 18, 2017Assignee: Dolby Laboratories Licensing CorporationInventors: Eric Kozak, Scott Daly

Patent number: 9426453Abstract: Methods and apparatus for signaling timing of refreshes of stereographic displays are provided. In some embodiments, light emitting elements are used to signal the start of a display refresh and to signal when the light emitting elements of the display have attained a stable optical state following the display refresh. In some embodiments, light emitting elements used to signal timing of display refreshes include light emitting elements defining a display area of the display.Type: GrantFiled: March 2, 2012Date of Patent: August 23, 2016Assignee: Dolby Laboratories Licensing CorporationInventors: Eric Kozak, Neil W.

Patent number: 9131097Abstract: Black bars are determined by lines of pixels. Steps include: for each line (or subset), determining standard deviation (or product value) and a difference value, product value being proportional to M·?, where M is pixel values mean for the line, ? standard deviation of pixel values for the line, and the difference value a difference between the standard deviation (or product) value for the line and the standard deviation (or product) value for one of the lines adjacent to the line, and determining whether any of the lines satisfies the criterion that the difference value for the line exceeds a threshold but the difference value for each other one of the lines to be displayed nearer to a first edge of the image than is the line does not exceed the threshold. Other aspects are a system or device configured (e.g., programmed) to perform any embodiment of the method.Type: GrantFiled: September 13, 2012Date of Patent: September 8, 2015Assignee: Dolby Laboratories Licensing CorporationInventors: Timo Kunkel, Eric Kozak

Patent number: 8786585Abstract: In one embodiment the present invention includes a method that adjusts a display device according to a display environment. The method includes sensing the display environment of the display device and generating environment data that corresponds to the display environment. The environment data includes color data. The method further includes adjusting a color appearance model according to the color data, generating a control signal according to the color appearance model having been adjusted, and controlling a backlight of the display device according to the control signal. In this manner, a viewer perceives the images displayed by the display device in the manner intended by the content creator, because the adjustments to the color appearance model compensate for the viewer's physiological response to the display environment.Type: GrantFiled: February 18, 2011Date of Patent: July 22, 2014Assignee: Dolby Laboratories Licensing CorporationInventors: Peter W.
