Publication number: 20160269654Abstract: An apparatus for capturing two different types of light simultaneously is described. A filter array is used for filtering light arriving at an image sensor. The filter array comprises per pixel filters arranged in rows, so if a row comprises filters, they are all of the same type. Different exposure settings may be used for rows having different filter configurations.Type: ApplicationFiled: March 9, 2015Publication date: September 15, 2016Inventors: Gustaf Pettersson, Johan Windmark, Jens Månsson, Radu Bilcu, Jörg Linke, Pasi Syvaenen

Patent number: 9401027Abstract: A method, apparatus and computer program product are provided to facilitate scene segmentation from focal stack images. The method may include receiving a set of focal stack images, calculating a focal measure for each of a plurality of pixels of the set of focal stack images, and grouping each of a plurality of pixels for which the focal measure was calculated into a plurality of super pixels. The method may also include calculating a focal measure for each of the plurality of super pixels, segmenting a respective focal stack image based on the focal measure of each of the plurality of super pixels, calculating a color probability for each of the plurality of super pixels, and segmenting each focal stack image based on color probability of each of the plurality of super pixels.Type: GrantFiled: October 21, 2013Date of Patent: July 26, 2016Assignee: Nokia Technologies OyInventors: Hui Zhou, Timo Ahonen, Karim Benchemsi, Tobias Karlsson, Amer Mustajbasic, Johan Windmark

Patent number: 9396569Abstract: There is disclosed a method for seamlessly replacing areas in a digital image with corresponding data from temporally close digital images depicting substantially the same scene. The method uses localized image registration error minimization over a fixed preliminary boundary. A least cost closed path which constitutes a boundary for the area to be replaced is calculated using dynamic programming. The replacement area is blended such that image data information from one image is seamlessly replaced with image data information from another image.Type: GrantFiled: September 26, 2013Date of Patent: July 19, 2016Assignee: Mobile Imaging in Sweden ABInventors: Alexander Lindskog, Gustaf Pettersson, Ulf Holmstedt, Johan Windmark, Sami Niemi

Publication number: 20160125633Abstract: In an example embodiment a method, apparatus and computer program product are provided. The method includes facilitating access of a plurality of images associated with a scene comprising at least one moving object, and segmenting the plurality of images into foreground regions and background regions based on changes in corresponding image regions between the images. The foreground regions comprise the at least one moving object. The method includes determining at least one object parameter associated with the at least one moving object in the foreground regions and generating a background image based on the background regions, and modifying at least one of the foreground regions and the background image to represent a motion of the at least one moving object based on the at least one object parameter. The method includes generating a composite image based on the modified at least one of the foreground regions and the background image.Type: ApplicationFiled: May 13, 2013Publication date: May 5, 2016Applicant: Nokia Technologies OyInventors: Johan Windmark, Alexander Lindskog, Tobias Karlsson
