A photographing unit photographs images about a biological tissue in a live body and generates a 3D image about the biological tissue using the produced depth information.
PURPOSE: An image processing device and a method thereof are provided to display a lesion by a 3D image. CONSTITUTION: A photographing unit(112) photographs images about a biological tissue in a live body. An extracting unit(120) extracts at least two images with a large image correlation degree from the photographed images. A controller(130) produces depth information from the extracted images. The controller generates a 3D image about the biological tissue using the produced depth information. A driving control unit(140) controls the photographing unit.
