Abstract

An image capturing device includes a first lens module, a second lens module and an operation module. The first lens module and the second lens module capture a first image and a second image respectively. The operator transforms a first section of a first left block of the first image and a second section of a second right block of the second image to a first color space image and a second color space image, obtains a shifting value of a minimum color space distance according to the first color space image and the second color space image, adjusts the width of the first left block and the second right block according to the shifting value of the minimum color space distance, and produces a third image in accordance with the adjusted first image, the adjusted second image and a blending operation.
