Publication number: 20250097480Abstract: 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: November 26, 2024Publication date: March 20, 2025Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Robin Atkins, Peng Yin, Taoran Lu, Jaclyn Anne Pytlarz

Publication number: 20250095125Abstract: Methods and systems for dynamic range conversion and display mapping of standard dynamic range (SDR) images onto high dynamic range (HDR) displays are described. Given an SDR input image, a processor generates an intensity (luminance) image and optionally a base layer image and a detail layer image. A first neural network uses the intensity image to predict statistics of the SDR image in a higher dynamic range. These predicted statistics together with the original image statistics of the input image are used to derive an optimal tone-mapping curve to map the input SDR image onto an HDR display. Optionally, a second neural network, using the intensity image and the detail layer image, can generate a residual detail layer image in a higher dynamic range to enhance the tone-mapping of the base layer image into the higher dynamic range.Type: ApplicationFiled: July 22, 2022Publication date: March 20, 2025Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Robert Wanat, Anustup Kumar Atanu Choudhury, Robin Atkins

Publication number: 20250054204Abstract: Systems and methods for encoding and decoding multiple-intent images and video using metadata. When encoding an image as a multiple-intent image, at least one appearance adjustment may be made to the image. Metadata characterizing the at least one appearance adjustment may be included in, or transmitted along with, the encoded multiple-intent image. When decoding a multiple-intent image, a system may obtain a selection of a desired rendering intent and, based on that selection, either render the multiple-intent image with the applied appearance adjustments or may use the metadata to invert the appearance adjustments and recover the image pre-appearance adjustments.Type: ApplicationFiled: September 27, 2022Publication date: February 13, 2025Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Robin Atkins, Jaclyn Anne Pytlarz, Robert Wanat, Jake William Zuena

Patent number: 12217724Abstract: 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: GrantFiled: December 18, 2023Date of Patent: February 4, 2025Assignee: Dolby Laboratories Licensing CorporationInventors: Jon Scott Miller, Scott Daly, Mahdi Nezamabadi, Robin Atkins

Patent number: 12170815Abstract: The described embodiments include systems and methods for producing and adapting images, such as video images, for presentation on display devices that have various different aspects ratios, such as 4:3, 16:9, 9:16, etc. In one embodiment, a method for producing content, such as video images, can begin by selecting an original aspect ratio and determining, within at least a first scene in the content, a position of a subject in the first scene. In one embodiment, the original aspect ratio can be substantially square (e.g., 1:1). Metadata can then be created, based on the position of the subject in the first scene, to guide playback devices to asymmetrically crop the content, relative to the position, for display on display devices that have aspect ratios that are different than the original aspect ratio. Other methods and systems are also described.Type: GrantFiled: June 9, 2021Date of Patent: December 17, 2024Assignee: Dolby Laboratories Licensing CorporationInventors: Robin Atkins, Suzanne Farrell, Per Jonas Andreas Klittmark

Publication number: 20240397088Abstract: Methods and systems for generating and using dynamic spatial metadata in image and video processing are described. In an encoder, in addition to global metadata, local, spatial metadata for two or more image regions or image objects are generated, smoothed, and embedded as spatial metadata values. In a decoder, the decoder can reconstruct the spatial metadata and use interpolation techniques to generate metadata for specific regions of interest. Examples of generating spatial metadata related to min, mid, and max luminance values in an image are provided.Type: ApplicationFiled: September 20, 2022Publication date: November 28, 2024Applicant: Dolby Laboratories Licensing CorporationInventors: Robin ATKINS, Per Jonas Andreas KLITTMARK

Patent number: 12100426Abstract: A content-creation tool includes a processor and a memory. The processor is configured to receive a first video clip and a second video clip, a respective first and second metadata-item thereof being set to a respective first and second metadata-value. The memory stores video-editing software that includes a timeline interface and instructions that, when executed by the processor, control the processor to: add the first video clip to the timeline interface as a first timeline-track that retains the first metadata-value; add the second video clip to the timeline interface as a second timeline-track that retains the second metadata-value; and generate a frame sequence that includes a plurality of video frames. Each video frame is a frame of, or a frame derived from, one of (i) the first timeline-track, (ii) the second timeline-track, and (iii) a composited time-line-track composited from at least one of the first and second timeline-tracks.Type: GrantFiled: July 7, 2021Date of Patent: September 24, 2024Assignee: Dolby Laboratories Licensing CorporationInventors: Robin Atkins, Gaven Wang
