1. A system for image capturing and depth extraction, the system comprising:
- a lens system;
a spectrum coded aperture including at least two regions that pass spectrum channels of an incident light field which are different from each other; and
a sensor configured to record the at least two spectrum channels to form an image captured in a sensor basis; and
a data processor configured to convert the image captured in the sensor basis into an image of a processing basis, extract a disparity from the image of the processing basis, and convert the disparity into depth information.

Abstract
A system for image capturing and depth extraction includes a camera and a data processor. The camera includes: a spectrum coded aperture including at least two regions that pass spectrum channels of an incident light field which are different from each other; and a sensor configured to record the at least two spectrum channels to form an image captured in a sensor basis. The data processor is configured to convert the image captured in the sensor basis into an image of a processing basis, extract a disparity from the image of the processing basis, and convert the disparity into depth information.

15. A method of image capturing and depth extraction, the method comprising:
-
recording at least two shifted spectrum channels of a light field to form an image captured from a video; converting the captured image into an image of a processing basis; estimating a disparity based on a correlation between pixels of the spectrum channels in the processing basis to extract a disparity map; restoring the captured image based on the extracted disparity map; and converting the disparity map into a depth map. - View Dependent Claims (16, 17, 18, 19)

20. A mobile device for image capturing and depth extraction in ultraviolet light, infrared light, or visible light, the mobile device comprising:
-
a lens system; at least one spectrum coded aperture including at least two regions that pass spectrum channels of an incident light field which are different from each other; a sensor configured to record the at least two spectrum channels to form an image captured in a sensor basis; and a coded aperture fixture configured to move at least one spectrum coded aperture relatively with respect to the lens system; and a data processor configured to convert the image captured in the sensor basis into an image of a processing basis, extract a disparity from the image of the processing basis, and convert the disparity into depth information. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
