Patent ID: 8279265

Claim:
An automatic capturing method of a panoramic image for a digital camera, applicable to a digital camera, the automatic capturing method comprising: capturing a first image; selecting a region from the first image and setting the region to an alignment image, wherein the selecting step comprises: obtaining a maximum width of the first image; defining a width of the alignment image according to a preset ratio and the maximum width; selecting the alignment image from the first image according to the width; dividing the alignment image into a plurality of regions; calculating an image standard deviation of each of the regions, and comparing the image standard deviation with a preset feature value; and selecting a feature point from the region with the image standard deviation greater than the feature value; continuously tracking and calculating a motion vector value of the alignment image in a real-time image, and accumulating the motion vector value to obtain an accumulated motion vector value; determining whether the accumulated motion vector value reaches a preset threshold value or not; if yes, automatically capturing a second image by the digital camera; and stitching and blending the first image and the second image to obtain a panoramic image.
