Reduced hardware implementation for a two-picture depth map algorithm
First Claim
Patent Images
1. A computerized method comprising:
- generating a first and second reduced resolution image using reduction information for the first and second reduced resolution image, the first and second reduced resolution image having a pixel size;
computing a blur difference in the first and second reduced resolution images, wherein a blur radius of the blur difference is larger than the pixel size; and
calculating a depth map based on the blur difference of the first and second reduced resolution images.

Abstract
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.
