Patent number: 11908104Abstract: In order to more accurately white balance an image, weightings can be determined for pixels of an image when computing an illuminant color value of the image and/or a scene. The weightings can be based at least in part on the Signal-to-Noise Ratio (SNR) of the pixels. The SNR may be actual SNR or SNR estimated from brightness levels of the pixels. SNR weighting (e.g., SNR adjustment) may reduce the effect of pixels with high noise on the computed illuminant color value. For example, one or more channel values of the illuminant color value can be determined based on the weightings and color values of the pixels. One or more color gain values can be determined based on the one or more channel values of the illuminant color value and used to white balance the image.Type: GrantFiled: September 6, 2022Date of Patent: February 20, 2024Assignee: NVIDIA CorporationInventors: Hamidreza Mirzaei Domabi, Eric Dujardin, Animesh Khemka, Yining Deng

Patent number: 11704781Abstract: The various embodiments of the present disclosure are directed towards methods for tone mapping High-Dynamic-Range (HDR) image data, as well as controlling the brightness of the image encoded by HDR the image data and/or the tone-mapped image data. HDR image is captured. A tone mapping function for the HDR image data is generated. To generate the tone mapping function, control points are dynamically determined based on an analysis of the HDR image data. The tone mapping function is fit to the control points. The tone mapping function is a non-linear function, and is described by a curve in a plane. The shape of the curve is constrained by a line generated from a portion of the control points. The tone mapping function is applied to the HDR image data. A color-compression is applied to the tone mapped image data to generate Standard Dynamic Range or Low Dynamic Range image data.Type: GrantFiled: October 13, 2021Date of Patent: July 18, 2023Assignee: NVIDIA CorporationInventors: Yining Deng, Eric Dujardin, Hamidreza Mirzaei Domabi, Sung Hyun Hwang

Patent number: 9762791Abstract: Techniques are disclosed for identifying preferred orientations of a face in view of various preference factors and for producing a face image having a preferred orientation. The techniques allow a user to take a so-called selfie or have a video chat and appear as if he/she is looking into the camera with a face orientation that has been determined to be optimal for various factors. Such factors may be associated with face type (e.g., face shape, face color), image capture conditions (e.g., time of day, location, light condition, background), and/or the preferences of a particular user. The factors may also be directly associated with and/or dependent on face orientation (e.g., relative nostril size, facial symmetry, relative eye size, eye height).Type: GrantFiled: November 7, 2014Date of Patent: September 12, 2017Assignee: INTEL CorporationInventor: Yining Deng

Patent number: 9432590Abstract: One embodiment of the present invention sets forth a technique for reducing flicker in image frames captured with a rolling shutter. A flicker detection and correction engine selects a first channel from a first image frame for processing. The flicker detection and correction engine subtracts each pixel value in the first channel from a corresponding pixel value in a prior image frame to generate a difference image frame. The flicker detection and correction engine identifies a first alternating current (AC) component based on a discrete cosine transform (DCT) associated with the difference image frame. The flicker detection and correction engine reduces flicker that is present in the first image frame based on the first AC component. One advantage of the disclosed techniques is that the flicker resulting from fluctuating light sources is correctly detected and reduced or eliminated irrespective of the frequency of the fluctuating light source.Type: GrantFiled: January 22, 2014Date of Patent: August 30, 2016Assignee: NVIDIA CorporationInventors: Hugh Phu Nguyen, Yining Deng, Eric Francois Xavier Dujardin, Abhinav Sinha
