Abstract:
1. An image depth information refreshing method applied to an image depth information refreshing device, wherein the image depth information refreshing device comprises a storage unit and an arithmetic logic unit, the storage unit stores a previous depth diagram corresponding to a previous image, and the image depth information refreshing method comprises: dividing a current image into a plurality of image blocks by the arithmetic logic unit, wherein the current image is captured by an image capturing unit; calculating a depth reference value of each image block according to the previous depth diagram and determining a weight of each image block according to the depth reference values by the arithmetic logic unit; determining a refreshing frequency of each image block according to the weights by the arithmetic logic unit; and respectively refreshing the image blocks according to the refreshing frequencies of the image blocks and generating a current depth diagram corresponding to the current image by the arithmetic logic unit.
