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.
Claims20
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, using at least one additional signal-measuring component coupled to the camera to capture scene photogrammetric data;
- 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.
A camera apparatus comprising a processor and a memory coupled to the processor;
- wherein the memory holds program instructions, that when executed by the processor, causes the apparatus to perform:
- 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, using at least one additional signal-measuring component coupled to the camera to capture scene photogrammetric data;
- 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.
