Method of capturing images and image capturing device using the method

A method of capturing images applicable to an image capturing device having a first lens module, a second lens module, a feature extraction unit, an image zooming-deformation unit and an image merging unit, wherein a view angle of the first lens module being larger than that of the second lens module, and the method comprising:

• (a) increasing an exposure time and reducing a light sensitivity value of the first lens module, and capturing a first image by using the first lens module;
• (b) reducing an exposure time and increasing a light sensitivity value of the second lens module, and capturing a second image by using the second lens module, wherein the light sensitivity value of the second lens module is larger than that of the first lens module;
• (c) respectively extracting a plurality of image features from the first image and the second image by using the feature extraction unit, and generating an overlapping region corresponding to the second image in the first image based on the plurality of image features;
• (d) respectively zooming and deforming the second image and the overlapping region corresponding to the second image in the first image by the image zooming-deformation unit;
• and
• (e) merging the zoomed and deformed second image into the zoomed and deformed overlapping region in the first image by the image merging unit to generate an output image.
