- camera designs that are much more easily adjustable; users change a single attenuating mask rather than arrays of lenses. We call this Dappled Photography, as the mask shadows the incoming light and dapples the sensor. We exploit the fact that light rays can be linearly combined: rather than sense each 4D ray on its own pixel sensor,

- Abstract We describe a theoretical framework for reversibly modulating 4D light fields using an attenuating mask in the optical path of a lens based camera. Based on this framework, we present a novel design to reconstruct the 4D light field from a ... Dappled photography: Mask enhanced cameras for heterodyned light fields and coded aperture ...

- Our mask-equipped camera focuses just as a traditional camera might to capture conventional 2D photos at full sensor resolution, but the raw pixel values also hold a modulated 4D light field. The light field can be recovered by rearranging the tiles of the 2D Fourier transform of sensor values into 4D planes, and computing the inverse Fourier transform.

- The patterned mask attenuates light rays inside the camera instead of bending them, and the attenuation recoverably encodes the rays on the 2D sensor. Our mask-equipped camera focuses just as a traditional camera to capture conventional 2D photos at full sensor resolution, but the raw pixel values also hold a modulated Keyphrases
