Abstract
An image capturing device adapted to capture a plurality of images of an object and an image capturing method are provided. The image capturing device includes an image sensing element, a first lens element, a second lens element and a variable focal length lens element. The image sensing element includes a plurality of image sensing pixels. The first lens element focuses a beam coming from the object to a focus position in a range of depth of focus. The variable focal length lens element is disposed between the first lens element and the second lens element or inside the first lens element, and is configured to adjust a focus object distance of the image capturing device. The beam has an image width on an image plane of the range of depth of focus. The image width is smaller than a first pixel width.
