20090268985 | Reduced Hardware Implementation For A Two-Picture Depth Map Algorithm - An imaging system generates a picture depth map from a pair of reduced resolution images. The system captures two full resolution images, receives image reduction image information and creates two reduced resolution images. The system computes a blur difference between the two reduced resolution images at different image locations. The system calculates the depth map based on the blur difference between the two reduced resolution images at different image locations. | 10-29-2009 |
