Patent number: 11594159Abstract: A display apparatus, a display management module and a method for ambient light compensation are described. The display management module is configured to receive an input video signal comprising a sequence of video frames and to determine whether a current video frame of the sequence of video frames immediately follows a scene change. The display management module is further configured to adjust ambient light compensation applied to the input signal in dependence on the signal indicative of intensity of ambient light only in response to determining that the current video frame of the sequence of video frames immediately follows a scene change.Type: GrantFiled: January 9, 2020Date of Patent: February 28, 2023Assignee: Dolby Laboratories Licensing CorporationInventors: Robin Atkins, Craig Todd, Jaclyn Anne Pytlarz, Timo Kunkel

Publication number: 20220375378Abstract: An embodiment of the disclosure provides a method and a system to sense a light source based on a viewer position in relation to display device. The system receives sensor data from one or more light sensors mounted on a wearable device worn by a viewer of a display device in a room, where a field of view for the light sensors covers at least a field of view of the viewer. The system identifies a light source perceived in a field of view of the viewer based on the sensor data. The system transmits data for one or more operations to be performed by the display device displaying content to the viewer to compensate for a change in brightness or color of the content caused by the light source based at least in part on light source information of the light source.Type: ApplicationFiled: September 3, 2020Publication date: November 24, 2022Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventor: Timo Kunkel

Patent number: 10977764Abstract: A spherical image of a spatial environment is received and contains spherically arranged pixel values indexed by a time value. The spherical image is represented in a content creation coordinate system in reference to a spatial position in the spatial environment. The spatial position is indexed by the time value. A spatial relationship is determined between the content creation coordinate system and a spherical image reference coordinate system. Based at least in part on the spatial relationship and the spherically arranged pixel values, spherical distributions of image metadata are determined for the spherical image.Type: GrantFiled: December 22, 2016Date of Patent: April 13, 2021Assignee: Dolby Laboratories Licensing CorporationInventors: Timo Kunkel, Cristina Michel Vasco, Scott Daly

Patent number: 10977849Abstract: Systems and methods for overlaying a second image/video data onto a first image/video data are described herein. The first image/video data may be intended to be rendered on a display with certain characteristics—e.g., HDR, EDR, VDR or UHD capabilities. The second image/video data may comprise graphics, closed captioning, text, advertisement—or any data that may be desired to be overlaid and/or composited onto the first image/video data. The second image/video data may be appearance mapped according to the image statistics and/or characteristics of the first image/video data. In addition, such appearance mapping may be made according to the characteristics of the display that the composite data is to be rendered. Such appearance mapping is desired to render a composite data that is visually pleasing to a viewer, rendered upon a desired display.Type: GrantFiled: November 5, 2019Date of Patent: April 13, 2021Assignee: Dolby Laboratories Licensing CorporationInventors: Timo Kunkel, Ning Xu, Tao Chen, Bongsun Lee, Samir N.

Patent number: 10979613Abstract: Methods, systems, and computer program products for automatically positioning a content capturing device are disclosed. A vehicle, e.g., an UAV, carries the content capturing device, e.g., a camcorder. The UAV can position the content capturing device at a best location for viewing a subject based on one or more audio or visual cues. The UAV can follow movement of the subject to achieve best audio or visual effect. In some implementations, a controller device carried by the subject can generate one or more signals for the UAV to follow. The controller device may be coupled to a microphone that records audio. The signals can be used to temporally synchronize video captured at the UAV and audio captured by the microphone.Type: GrantFiled: October 17, 2017Date of Patent: April 13, 2021Assignee: Dolby Laboratories Licensing CorporationInventors: Timo Kunkel, Cong Zhou, Vivek Kumar, Remi S.

Patent number: 10540920Abstract: A display management processor receives an input image with enhanced dynamic range to be displayed on a target display which has a different dynamic range than a reference display. The input image is first transformed into a perceptually-corrected IPT color space. A non-linear mapping function generates a first tone-mapped signal by mapping the intensity of the input signal from the reference dynamic range into the target dynamic range. The intensity (I) component of the first tone-mapped signal is sharpened to preserve details, and the saturation of the color (P and T) components is adjusted to generate a second tone-mapped output image. A color gamut mapping function is applied to the second tone-mapped output image to generate an image suitable for display onto the target display. The display management pipeline may also be adapted to adjust the intensity and color components of the displayed image according to specially defined display modes.Type: GrantFiled: February 13, 2014Date of Patent: January 21, 2020Assignee: Dolby Laboratories Licensing CorporationInventors: Robin Atkins, Timo Kunkel, Thaddeus Beier, Tao Chen
