Abstract:
1. A three-dimensional (3D) video camera, comprising: a first camera lens configured to provide a first sensing signal by a first sensing element; a second camera lens configured to provide a second sensing signal by a second sensing element, wherein the first camera lens and the second camera lens have different resolutions; and an image processing unit configured to receive the first sensing signal and the second sensing signal to generate a first eye image and a first comparison image, and to generate 3D depth information according to the first eye image and the first comparison image, wherein the image processing unit is configured to process the first comparison image with reference to the first eye image to obtain a second comparison image, and generate the 3D depth information by comparing the first eye image and the second comparison image to calculate horizontal distances between same objects in the first eye image and the second comparison image resulting from visual differences between the same objects in the first eye image and the second comparison image, wherein the calculated horizontal distances represent the 3D depth information; wherein the first comparison image is processed with scaling or decolorizing before the horizontal distances representative of 3D depth information are calculated according to the first eye image and the first comparison image; and wherein the image processing unit comprises: a 3D video camera further comprises a 3D depth interpolation unit configured to receive the block base 3D depth and perform an interpolation to obtain a sub-block base 3D depth as the 3D depth information.
