Publication number: 20230196963Abstract: Methods and systems for chromatic ambient-light support are provided. Given an input surround correlated color temperature (CCT), its normalized value is mapped to a preferred gray CCT value using a sigmoid-like function model generated based on viewer experimental data. The preferred gray CCT value is then mapped to an adjusted CCT value so that viewing conditions on a display with the input surround CCT value match a D65 surround CCT value.Type: ApplicationFiled: April 16, 2021Publication date: June 22, 2023Applicant: Dolby Laboratories Licensing CorporationInventors: Jake William Zuena, Jaclyn Anne Pytlarz, Robin Atkins

Publication number: 20230120882Abstract: 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 22, 2022Publication date: April 20, 2023Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Robin Atkins, Peng Yin, Taoran Lu, Jaclyn Anne Pytlarz

Publication number: 20230105944Abstract: 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 7, 2022Publication date: April 6, 2023Applicant: Dolby Laboratories Licensing CorporationInventors: Jon Scott MILLER, Scott DALY, Mahdi NEZAMABADI, Robin ATKINS

Publication number: 20220398710Abstract: Methods and systems for generating an image quality metric are described. A reference and a test image are first converted to the ITP color space. After calculating difference images ?I, ?T, and ?P, using the color channels of the two images, the difference images are convolved with low pass filters, one for the I channel and one for the chroma channels (I or P). The image quality metric is computed as a function of the sum of squares of filtered ?I, ?T, and ?P values. The chroma low-pass filter is designed to maximize matching the image quality metric with subjective results.Type: ApplicationFiled: June 10, 2021Publication date: December 15, 2022Applicant: Dolby Laboratories Licensing CorporationInventors: Robert WANAT, Robin ATKINS, Anustup Kumar Atanu CHOUDHURY, Scott DALY, Jaclyn Anne PYTLARZ
