Abstract

A monoscopic low-power mobile device is capable of creating real-time images and videos for multiple viewpoints from a single captured view. The device uses statistics from an autofocusing process to create a block depth map of a single capture view. Artifacts in the block depth map are reduced and an image depth map is created. Alternate views are created from the image depth map using a Z-buffer based surface recover process and a disparity map which is a function of a geometric vision model.

First claim

What is claimed is:

1. A monoscopic low-power mobile device comprising:
a single-sensor camera configured to capture an image from a first viewpoint;
an autofocusing module configured to determine a best focus position by moving a lens of the single-sensor camera through an entire focusing range via a focusing process and to select the focus position with a maximum focus value when capturing the image;
a depth map generator assembly in data communication with the autofocusing…
