Patent number: 11887560Abstract: 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 7, 2022Date of Patent: January 30, 2024Assignee: Dolby Laboratories Licensing CorporationInventors: Jon Scott Miller, Scott Daly, Mahdi Nezamabadi, Robin Atkins

Patent number: 10701375Abstract: A tone-mapping function that maps input images of a high dynamic range into reference tone-mapped images of a relatively narrow dynamic range is generated. A luma forward reshaping function is derived, based on first bit depths and second bit depths, for forward reshaping luma codewords of the input images into forward reshaped luma codewords of forward reshaped images approximating the reference tone-mapped images. A chroma forward reshaping mapping is derived for predicting chroma codewords of the forward reshaped images. Backward reshaping metadata that is to be used by recipient devices to generate a luma backward reshaping function and a chroma backward reshaping mapping is transmitted with the forward reshaped images to the recipient devices. Techniques for the joint derivation of forward luma and chroma reshaping functions are also presented.Type: GrantFiled: March 22, 2017Date of Patent: June 30, 2020Assignee: Dolby Laboratories Licensing CorporationInventors: Guan-Ming Su, Jon Scott Miller, Walter J.

Patent number: 10419762Abstract: A content-adaptive quantizer processor receives an input image with an input bit depth. A noise-mask generation process is applied to the input image to generate a noise mask image which characterizes each pixel in the input image in terms of its perceptual relevance in masking quantization noise. A noise mask histogram is generated based on the input image and the noise mask image. A masking-noise level to bit-depth function is applied to the noise mask histogram to generate minimal bit depth values for each bin in the noise mask histogram. A codeword mapping function is generated based on the input bit depth, a target bit depth, and the minimal bit depth values. The codeword mapping function is applied to the input image to generate an output image in the target bit depth.Type: GrantFiled: March 1, 2016Date of Patent: September 17, 2019Assignees: Dolby Laboratories Licensing Corporation, Dolby International ABInventors: Jan Froehlich, Guan-Ming Su, Robin Atkins, Scott Daly, Jon Scott Miller

Patent number: 9716887Abstract: Methods to reduce chroma-related artifacts during video coding of high dynamic range images are presented. Given an input signal in a color space comprising a luma component and two chromaticity components, a processor determines the original white point chromaticity coordinates (Du, Dv) of a white point in the color space of the input signal. The input signal is translated using a chromaticity translation function to a second signal in a translated color space comprising two translated chromaticity components, wherein the chromaticity translation function shifts the original white point chromaticity coordinates to a predetermined second set of coordinates in the translated chromaticity color space. The second signal is encoded to generate a coded bit stream.Type: GrantFiled: December 6, 2016Date of Patent: July 25, 2017Assignee: Dolby Laboratories Licensing CorporationInventors: Robin Atkins, Jon Scott Miller
