Plenoptic camera comprising a spatial light modulator and method of acquiring views with such a plenoptic camera

摘要

A plenoptic camera (2) comprising a camera lens, a lenslet array (11) with microlenses and a photosensors array (13) with photosensors, wherein the camera lens comprises a spatial light modulator SLM (20) arranged in the aperture stop plane of the camera lens. A group of photosensors is associated with each microlens, a group of cells of the SLM (20) is associated with each photosensor of the group of photosensors, each cell being configured to switch between a first state (to block the light) and a second state (to let the light pass through the cell). A first part of the cells of the group of cells is in the first state during a first acquisition time of a first image, cells of the group of cells not belonging to the first part being in the second state during the first acquisition time. A second part of the cells of the group of cells is in the first state during a second acquisition time of at least a second image, cells of the group of cells not belonging to the second part being in the second state during the second acquisition time, the second part being different from the first part and the first and the second acquisition times being temporally consecutive.
