Publication number: 20240107177Abstract: Embodiments disclosed herein are directed to devices and methods for performing spatially-varying brightness correction of a flash image. The spatially-varying brightness correction utilizes a set of images that includes one or more images captured under flash illumination and one or more images captured without flash illumination, which are used to decompose one of the flash images or an image generated therefrom into a flash contribution image and an ambient contribution image. The flash contribution image and the ambient contribution image are recombined to generate a corrected flash image, and information about the flash module and/or scene is used to adjust the relative contributions of these images during recombination.Type: ApplicationFiled: September 22, 2022Publication date: March 28, 2024Inventors: Bosheng Zhang, Tobias Baldauf, llya Romanenko, Nicolas P. Bonnier, Noah D. Bedard, Alexandra S. Ludlow, Graham D. Finlayson, Jason P. de Villiers, Claus Moelgaard, Hau Ling Hung, Paul M. Hubel

Patent number: 9942486Abstract: For cameras that capture several images in a burst mode, some embodiments of the invention provide a method that presents one or more of the captured images differently than the remaining captured images. The method identifies at least one captured image as dominant image and at least another captured image as a non-dominant image. The method then displays each dominant image different from each non-dominant image in a concurrent presentation of the images captured during the burst mode. The dominant images may appear larger than non-dominant images, and/or appear with a marking that indicates that the images are dominant.Type: GrantFiled: April 4, 2016Date of Patent: April 10, 2018Assignee: APPLE INC.Inventors: Claus Mølgaard, Mikael Rousson, Vincent Yue-Tao Wong, Brett M. Keating, Jeffrey A. Brasket, Karl C. Hsu, Todd S. Sachs, Justin Titi, Elliott B. Harris

Patent number: 8908053Abstract: A digital camera system has integrated accelerometers for determining static and dynamic accelerations of the digital cameral system. Data relating to static and dynamic accelerations are stored with recorded image data for further processing, such as for correcting image data for roll, pitch and vibrations and for displaying recorded images with a predetermined orientation using information about, e.g., roll. Data may also be used on-the-fly for smear suppression caused by vibrations.Type: GrantFiled: April 26, 2012Date of Patent: December 9, 2014Assignee: Phase One A/SInventor: Claus Mølgaard

Patent number: 7656561Abstract: Lossless, near-lossless, and lossy compression and decompression of digital image data, whereby the image data can be compressed and decompressed on-the-fly with no need for external RAM resources for temporary data storage while compressing/decompressing image data. Implementing the algorithm only requires a very limited amount of silicon and yields very high performance in relation to very low power consumption. The described implementation is optimized for raw image data from a sensor with a Bayer filter pattern but can be used on data from image sensors with ay color filter. The compression algorithm contains a line indexing formation which enables very fast subsampling of an already compressed image and the possibility to decompress only parts of an image—this improves performance and reduces the need for temporary RAM storage greatly when zooming and in postprocessing.Type: GrantFiled: June 14, 2004Date of Patent: February 2, 2010Assignee: Phase One A/SInventors: Claus Mølgaard, Thomas Alexander Rogon, Thomas Andersen
