Claim Text:
1. A block-based digital refocusing method, comprising: providing a capturing step, wherein the capturing step is for capturing at least one picture datum by a capturing module; providing a dividing step, wherein the dividing step is or dividing the picture datum into a plurality of block data by a dividing unit; providing a selecting step, wherein the selecting step is for defining a regional datum according to each of the block data by a selecting unit; providing a refocusing step, wherein the refocusing step for conducting a refocusing computation to obtain a refocused block datum according to each of the regional data by a refocusing unit; and providing a combining step, wherein the combining step is for combining each of the refocused block data based on each of the regional data to form a refocused picture datum by a combining unit; wherein the regional data are partially overlapped with each other, and there is an overlapping region in the two refocused block data which are corresponding to the two adjacent block data, respectively; wherein the picture datum comprises a plurality of view picture data, and the refocusing step is for conducting the refocusing computation according to the view picture data; wherein in the refocusing computation, a plurality of non-central viewpoints are shifted by a target disparity in each of the regional data, then a view interpolation is used to produce a plurality of new target pixels of a plurality of novel viewpoints and obtain the refocused block datum, and the view interpolation is for using the nearby view picture data to generate the novel viewpoints.
