Publication number: 20240155161Abstract: In a method to improve backwards compatibility when decoding high-dynamic range images coded in a wide color gamut (WCG) space which may not be compatible with legacy color spaces, hue and/or saturation values of images in an image database are computed for both a legacy color space (say, YCbCr-gamma) and a preferred WCG color space (say, IPT-PQ). Based on a cost function, a reshaped color space is computed so that the distance between the hue values in the legacy color space and rotated hue values in the preferred color space is minimized HDR images are coded in the reshaped color space. Legacy devices can still decode standard dynamic range images assuming they are coded in the legacy color space, while updated devices can use color reshaping information to decode HDR images in the preferred color space at full dynamic range.Type: ApplicationFiled: January 5, 2024Publication date: May 9, 2024Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Robin Atkins, Peng Yin, Taoran Lu, Jaclyn Anne Pytlarz

Publication number: 20240155095Abstract: A volumetric image of a scene can be created, in one embodiment, by recording, through a camera in a device, a series of images of the scene as the camera is moved along a path relative to the scene; during the recording, the device stores motion path metadata about the path, and the series of images is associated with the motion path metadata and a metadata label is associated with the series of images, the metadata label indicating that the recorded series of images represent a volumetric image of the scene. The series of images, the motion path metadata and the metadata label can be assembled into a package for distribution to devices that can view the volumetric image, which may be referred to as a limited volumetric image. The devices that receive the volumetric image can display the individual images in the series of images or as a video.Type: ApplicationFiled: May 5, 2022Publication date: May 9, 2024Applicant: Dolby Laboratories Licensing CorporationInventor: Robin ATKINS

Patent number: 11979589Abstract: Methods and systems for frame rate scalability are described. Support is provided for input and output video sequences with variable frame rate and variable shutter angle across scenes, or for input video sequences with fixed input frame rate and input shutter angle, but allowing a decoder to generate a video output at a different output frame rate and shutter angle than the corresponding input values. Techniques allowing a decoder to decode more computationally-efficiently a specific backward compatible target frame rate and shutter angle among those allowed are also presented.Type: GrantFiled: November 13, 2023Date of Patent: May 7, 2024Assignee: Dolby Laboratories Licensing CorporationInventors: Robin Atkins, Peng Yin, Taoran Lu, Fangjun Pu, Sean Thomas McCarthy, Walter J.

Publication number: 20240144895Abstract: A handheld imaging device has a data receiver that is configured to receive reference encoded image data. The data includes reference code values, which are encoded by an external coding system. The reference code values represent reference gray levels, which are being selected using a reference grayscale display function that is based on perceptual non-linearity of human vision adapted at different light levels to spatial frequencies. The imaging device also has a data converter that is configured to access a code mapping between the reference code values and device-specific code values of the imaging device. The device-specific code values are configured to produce gray levels that are specific to the imaging device. Based on the code mapping, the data converter is configured to transcode the reference encoded image data into device-specific image data, which is encoded with the device-specific code values.Type: ApplicationFiled: December 18, 2023Publication date: May 2, 2024Applicant: Dolby Laboratories Licensing CorporationInventors: Jon Scott MILLER, Scott DALY, Mahdi NEZAMABADI, Robin ATKINS

Patent number: 11941791Abstract: A method for generating a high-dynamic-range (HDR) image includes (a) denoising a short-exposure-time image, wherein the denoising comprises applying a first guided filter to the short-exposure-time image, the guided filter utilizing a long exposure-time-image as its guide, (b) after the step of denoising, scaling at least one of the short-exposure-time image and the long-exposure-time image to place the short-exposure-time image and the long-exposure-time image on a common radiance scale, and (c) after the step of scaling, merging the short-exposure-time image with the long-exposure-time image to generate the HDR image.Type: GrantFiled: April 9, 2020Date of Patent: March 26, 2024Assignee: Dolby Laboratories Licensing CorporationInventors: Jon S.

Publication number: 20240031543Abstract: In one embodiment, methods, media, and systems process and display light field images using a view function that is based on pixel locations in the image and on the viewer's distance (observer's Z position) from the display. The view function can be an angular view function that specifies different angular views for different pixels in the light field image based on the inputs that can include: the x or y pixel location in the image, the viewer's distance from the display, and the viewer's angle relative to the display. In one embodiment, light field metadata, such as angular range metadata and/or angular offset metadata can be used to process and display the image. In one embodiment, color volume mapping metadata can be used to adjust color volume mapping based on the determined angular views; and the color volume mapping metadata can also be adjusted based on angular offset metadata.Type: ApplicationFiled: December 2, 2021Publication date: January 25, 2024Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventor: Robin ATKINS

Patent number: 11875719Abstract: Two corresponding color patches are displayed on two image displays until adjusted by a viewer to match visually to a common color. Two sets of code values rendered on the two corresponding color patches on the two image displays are identified. Two sets of tristimulus values for the viewer are determined based on the two sets of code values rendered on the two corresponding color patches on the two image displays. The viewer's color matching function are generated based on the two sets of tristimulus values. The viewer's CMF is used in image rendering operations on a target image display.Type: GrantFiled: May 12, 2020Date of Patent: January 16, 2024Assignee: Dolby Laboratories Licensing CorporationInventors: Jaclyn Anne Pytlarz, Elizabeth G.
