Reduced Hardware Implementation For A Two-Picture Depth Map Algorithm

A machine readable medium having executable instructions to cause a processor to perform a method comprising:

• generating a first and second reduced resolution image using reduction information for the first and second reduced resolution image;
• computing a blur difference in the first and a second reduced resolution image;
• and
• calculating a depth map based on the blur difference of the first and second reduced resolution images.

An apparatus comprising:

• means for generating a first and second reduced resolution image using reduction information for the first and second reduced resolution image;
• means for computing a blur difference in the first and a second reduced resolution image;
• and
• means for calculating a depth map based on the blur difference of the first and second reduced resolution images.

A system comprising:

• a processor;
• a memory coupled to the processor though a bus;
• and
• a process executed from the memory by the processor to cause the processor to generate a first and second reduced resolution image using reduction information for the first and second reduced resolution image, compute a blur difference in the first and a second reduced resolution image, and to calculate a depth map based on the blur difference of the first and second reduced resolution images
