Patent number: 10192517Abstract: Source image content is adapted to a target display. Target image content associated with the target display is provided. A histogram is computed for the target image content. A prominent feature present in the target histogram is determined. A histogram is computed for the source image content. The source content histogram is manipulated to reflect the determined target histogram prominent feature(s). Adapted source image content is generated based on the manipulated source histograms(s). Another prominent feature present in the target histogram is determined. The source histogram is further manipulated to reflect the other prominent determined target histogram features. Further adapted source image content is generated based on the further manipulated source histogram if the adapted source image content has insufficient image quality and perceptual color characteristics.Type: GrantFiled: July 6, 2012Date of Patent: January 29, 2019Assignee: Dolby Laboratories Licensing CorporationInventors: Anders Ballestad, Gerwin Damberg

Publication number: 20190007660Abstract: Image display apparatus and methods may use a single imaging element such as a digital mirror device (DMD) to spatially modulate plural color channels. A color channel may include a light steering element such as a phase modulator. Steered light from a light steering element may be combined with or replaced by additional light to better display bright images. These technologies may be provided together or applied individually.Type: ApplicationFiled: August 21, 2018Publication date: January 3, 2019Inventors: Gerwin DAMBERG, Eric Jan KOZAK, Raveen KUMARAN, Anders BALLESTAD

In some embodiments optimization is performed to generate image data and control signals for each of the projectors. Embodiments may be applied in image projecting applications, lighting applications, and 3D stereoscopic imaging.Type: GrantFiled: November 22, 2016Date of Patent: January 1, 2019Assignee: MTT Innovation IncorporatedInventors: Eric Kozak, Gerwin Damberg, Anders Ballestad, Raveen Kumaran, James Gregson, Johannes Minor, Gil Rosenfeld

Publication number: 20180376115Abstract: Undesirably high energy-consumption in illuminating devices can be caused at least in part by wasted (attenuated) light. Optically efficient illumination systems that may be used to project light, including images, use light redirection. Phase modulating devices may be applied to create desired light fields. Some embodiments provide dual or multiple modulation display or projection systems in which some or all of the modulators not only attenuate amplitude, but also amplify amplitude, or change the phase, frequency and polarization of the light provided by the light source.Type: ApplicationFiled: August 21, 2018Publication date: December 27, 2018Inventors: Gerwin DAMBERG, Anders BALLESTAD

Publication number: 20180292053Abstract: A light source includes a plurality of laser diodes or other light emitters. Beams of light from the light emitters are steered to provide n array of parallel beams that illuminate a target area with an array of patches of light. In some embodiments the parallel beams are de-magnified to form the array of patches of light. Such a light source has application in illuminating dynamically-addressable focusing elements such as phase modulators, deformable mirrors and dynamically addressable lenses. Light projectors for a wide variety of applications may combine a light source as described herein with a dynamically-addressable focusing element to project defined patterns of light.Type: ApplicationFiled: January 5, 2018Publication date: October 11, 2018Inventors: Johannes Minor, Gerwin Damberg, Raveen Kumaran, Anders Ballestad, Eric Jan Kozak, Gil Rosenfeld, Eran Elizur

Publication number: 20180182352Abstract: Image data is transformed for display on a target display. A sigmoidal transfer function provides a free parameter controlling min-tone contrast. The transfer function may be dynamically adjusted to accommodate changing ambient lighting conditions. The transformation may be selected so as to automatically adapt image data for display on a target display in a way that substantially preserves creative intent embodied in the image data. The image data may be video data.Type: ApplicationFiled: February 22, 2018Publication date: June 28, 2018Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Anders Ballestad, Andrey Kostin

Publication number: 20180176519Abstract: A free-form lens (for example a phase modulator, lens or deformable mirror) may be made to reproduce a light pattern specified by image data. Source regions on the free-form lens are mapped to target regions areas on an image. Areas of the source regions are adjusted to vary the amount of light delivered to each of the target regions. Adjustment of the source areas may be achieved using a L-BFGS optimization which preferably incorporates smoothness and curl regularizers. Embodiments apply parallel processing to obtain control values for a free form lens in real time or near real time. Apparatus may process image data and display an image by controlling a dynamically variable free form lens using the processed image data.Type: ApplicationFiled: February 8, 2018Publication date: June 21, 2018Inventors: Gerwin DAMBERG, Anders BALLESTAD, Raveen KUMARAN, James GREGSON

Patent number: 9819974Abstract: Several embodiments of a media processor for the creation of metadata from a set of images are given. The media processor receives a set of image data and computes metadata from the image data. The metadata may comprise statistical data based on the image data; from which the media processor may generate and store a multi-scale version of the metadata. The metadata may comprise statistical attributes derived directly from the image data or statistical attributes derived from image appearance correlates of the image data. The media processor may generate a subsampled set of the metadata and the subsampled set may be stored in an efficient data structure, such as a pyramidal structure. The pyramidal structure may be generated from spatial image information, from temporal image information or from spatial-temporal image information.Type: GrantFiled: February 26, 2013Date of Patent: November 14, 2017Assignee: Dolby Laboratories Licensing CorporationInventors: Timo Kunkel, Anders Ballestad, Joel N.

Patent number: 9514508Abstract: An emulator yields modified image data that predicts the appearance of image content on a target display. The emulator generates modified image data based in part on the image content. The emulator may perform a transformation in which one or more parameters representative of features such as black level and/or white level of the target display are functions of image statistics for the image content.Type: GrantFiled: December 6, 2012Date of Patent: December 6, 2016Assignee: Dolby Laboratories Licensing CorporationInventors: Anders Ballestad, Robin Atkins, Lewis Johnson

Patent number: 9466098Abstract: A global image adjustment, such as dynamic range adjustment is established based on image characteristics. The image adjustment is based more heavily on pixel values in image areas identified as being important by one or more saliency mapping algorithms. In one application to dynamic range adjustment, a saliency map is applied to create a weighed histogram and a transformation is determined from the weighted histogram. Artifacts typical of local adjustment schemes may be avoided.Type: GrantFiled: November 26, 2014Date of Patent: October 11, 2016Assignee: Dolby Laboratories Licensing CorporationInventors: Anders Ballestad, Gerwin Damberg
