BLOCK-BASED DIGITAL REFOCUSING SYSTEM AND METHOD THEREOF

摘要

A block-based digital refocusing method includes a capturing step, a dividing step, a selecting step, a refocusing step and a combining step. The capturing step is for capturing at least one picture datum. The dividing step is for dividing the picture datum into a plurality of block data. The selecting step is for defining a regional datum according to each of the block data. The refocusing step is for conducting a refocusing computation to obtain a refocused block datum according to each of the regional data. 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.
