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.

用于在交互式计算设备上观看图像的计算机实现的方法包括从包括显示图像和名义上相同场景的至少一个压缩子图像的堆叠中显示图像,堆叠的每个子图像已被获取 在各自的焦距。 响应于用户选择显示图像的一部分,所选择的部分根据显示的图像和子图像之间的焦距的差异被映射到堆叠内的子图像的对应的映射部分。 至少一行在映射部分上延伸的至少一个子图像的压缩图像块的行; 并且确定压缩图像块行之前的子图像的压缩图像流中的点的参考值。 使用该参考,计算至少部分解码的子图像的块行和与解码图像块重合的映射部分的区域的焦点的度量,以确定至少该子图像的内容 应显示在显示图像中。
