Abstract
A camera includes a lens and a sensor. A dynamic mask is arranged at an aperture plane between the lens and the sensor, and a static mask is arranged immediately adjacent to the sensor. Angular, temporal or spatial variations in light rays acquired of a scene by the sensor are mapped to individual pixels of the sensor.

19. The method for acquiring an input image of a scene, comprising:
-
modulating a light field from a scene entering a camera through a lens at an aperture plane using a dynamic mask; and acquiring the modulated light field at a sensor as a single image using a static mask placed immediately adjacent to the sensor, wherein temporal variations of the light field are mapped to angular variations by partitioning an exposure time T into K2 intervals of duration T/K2, and during each of the K2 intervals, only one of the K2 locations of the dynamic mask is open, while all other locations are closed. - View Dependent Claims (20, 21, 22, 23, 24, 25)
