Patent number: 8849064Abstract: A computer-implemented method for viewing images on an interactive computing device comprises displaying an image from a stack comprising a display image and at least one compressed sub-image of nominally the same scene, each of the sub-images of the stack having been acquired at respective focal distances. Responsive to a user selecting a portion of the displayed image, the selected portion is mapped to a corresponding mapped portion of a sub-image within the stack according to the difference in focal distances between the displayed image and the sub-image. At least one row of compressed image blocks of the at least one sub-image extending across the mapped portion; and a reference value for a point in the compressed image stream of the sub-image preceding the row of compressed image blocks is determined.Type: GrantFiled: February 14, 2013Date of Patent: September 30, 2014Assignee: Fotonation LimitedInventors: Valentin Mocanu, Christopher Dainty, Petronel Bigioi, Peter Corcoran, Ferenc Papai
