METHOD AND APPARATUS FOR VIEWING IMAGES |
摘要 |
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. Using the reference, the row of blocks of the sub-image at least partially decoded, and a measure of focus for an area of the mapped portion coinciding with the decoded image blocks is computed to determine if at least that content of the sub-image should be displayed within a display image. |
