Patent number: 10242627Abstract: Systems and methods are disclosed for dynamically adjusting the backlight of a display during video playback. Given an input video stream and associated minimum, average, or maximum luminance values of the video frames in the video stream, values of a function of the frame min, mid, or max luminance values are filtered using a temporal filter to generate a filtered output value for each frame. The instantaneous dynamic range of a target display is determined based on the filtered output value and the minimum and maximum brightness values of the display. A backlight control level is computed based on the instantaneous dynamic range, and the input signal is tone mapped by a display management process to be displayed on the target display at the selected backlight level. The design of a temporal filter based on an exponential moving average filter and scene-change detection is presented.Type: GrantFiled: May 11, 2016Date of Patent: March 26, 2019Assignee: Dolby Laboratories Licensing CorporationInventors: Suzanne Farrell, Scott Daly, Robin Atkins, Timo Kunkel, Gregory John Ward, Samir N.

Patent number: 10242650Abstract: 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: April 23, 2018Date of Patent: March 26, 2019Assignee: Dolby Laboratories Licensing CorporationInventors: Jon Scott Miller, Scott Daly, Mahdi Nezamabadi, Robin Atkins

Patent number: 10027963Abstract: An encoder receives an input enhanced dynamic range (EDR) image and a corresponding lower dynamic range (LDR) image to be coded at a given target rate. Before coding, a pre-dithering process is applied to the input LDR image to generate a dithered LDR image at a second bit depth, lower than its original bit depth. The pre-dithering process includes: generating uniformly-distributed noise, applying a spatial filter to the noise to generate low-pass or high-pass filtered noise, applying a temporal high pass or low pass filter to the spatially-filtered noise to generate output noise, adding the output noise to the input LDR image to generate a noise-enhanced LDR image, and quantizing the noise-enhanced image to generate the dithered LDR image. Selecting the characteristics of the dithering filters is based on both the target bit rate and luminance characteristics of the pixels in the input LDR image.Type: GrantFiled: November 10, 2014Date of Patent: July 17, 2018Assignee: Dolby Laboratories Licensing CorporationInventors: Guan-Ming Su, Qian Chen, Bongsun Lee, Scott Daly

Patent number: 9762876Abstract: Dithering techniques for images are described herein. An input image of a first bit depth is separated into a luma and one or more chroma components. A model of the optical transfer function (OTF) of the human visual system (HVS) is used to generate dither noise which is added to the chroma components of the input image. The model of the OTF is adapted in response to viewing distances determined based on the spatial resolution of the chroma components. An image based on the original input luma component and the noise-modified chroma components is quantized to a second bit depth, which is lower than the first bit depth, to generate an output dithered image.Type: GrantFiled: April 2, 2014Date of Patent: September 12, 2017Assignee: Dolby Laboratories Licensing CorporationInventors: Scott Daly, Bongsun Lee
