Claims19
A plenoptic camera comprising a camera lens, a lenslet array comprising a plurality of microlenses and a photosensors array comprising a plurality of photosensors, wherein the camera lens comprises a spatial light modulator arranged in the aperture stop plane of the camera lens,
- wherein, a group of photosensors being associated with each microlens, a group of cells of the spatial light modulator being associated with each photosensor of said group of photosensors, the number of groups of cells being equal to the number of photosensors of said group associated with one microlens,
- wherein the plenoptic camera further comprises a controller configured to control the cells of said group of cells to control the amount of the light exiting said group of cells.
A method of controlling the quantity of light reaching a photosensor array of a plenoptic camera, the plenoptic camera comprising a camera lens and a lenslet array, a spatial light modulator arranged in the aperture stop plane of the camera lens, a group of photosensors being associated with each microlens, a group of cells of the spatial light modulator being associated with each photosensor of said group of photosensors, the number of groups of cells being equal to the number of photosensors of said group associated with one microlens, the method comprising controlling the cells of said group of cells to control the amount of light exiting said group of cells.
(canceled)
A telecommunication device comprising a plenoptic camera comprising a camera lens, a lenslet array comprising a plurality of microlenses and a photosensors array comprising a plurality of photosensors wherein the camera lens comprises a spatial light modulator arranged in the aperture stop plane of the camera lens, wherein, a group of photosensors being associated with each microlens, a group of cells of the spatial light modulator being associated with each photosensor of said group of photosensors, the number of groups of cells being equal to the number of photosensors of said group associated with one microlens, wherein the plenoptic camera further comprises a controller configured to control the cells of said group of cells to control the amount of the light exiting said group of cells.
