Simulated large aperture lens
First Claim
1. A method, comprising:
- capturing a photographic image data of a scene using a camera having a lens set to a first aperture size;
concurrently with capturing the image, capturing photogrammetric range data pertaining to depth of objects in a field of view of the camera, comprising illuminating the scene using multiple narrow-band lights spaced at different frequency bands including at least one narrow-band light adjacent to the lens, and measuring intensity of narrowband light reflected from objects in the scene for each frequency band; and
processing the photographic image data using the photogrammetric range data to obtain second photographic data simulating an image captured using a lens set to a second aperture size, wherein the second aperture size is wider than the first aperture size.

Abstract
A camera apparatus includes a photogrammetric range sensor, small aperture lens and a processor configured to carry out a method for simulating a large aperture lens. The method includes capturing a photographic image data of a scene using the camera with the lens set to a small aperture size. Simultaneously or near-simultaneously with capturing the image, the camera captures photogrammetric range data pertaining to depth of objects in a field of view of the camera, using the range sensor. The processor then processes the photographic image data using the photogrammetric range data to obtain second photographic data simulating an image captured using a lens set to an aperture size larger than the small aperture size.
