Right monitor, original 2-D endoscopic image; left monitor, processed 3-D image displayed in line-by-line mode. (a) The endoscope was set with an OATVA of 90°. (b) The endoscope was set at −60° from the midline of the participant and the image was rotated 60°, with a rectified OATVA of 90°. (c) The effect of image rotation on the task completion. |

The 3-D image with and without displayed angle rectification (right and middle monitor) is reconstructed by the imaging processor from the conventional 2-D endoscopic image (left monitor). The image reconstruction is carried out in real-time, and the time-gap for imaging procession is not realizable. |
