Abstract
A plenoptic imaging device (2) comprising a micro-lens array (MLA) placed between a main lens (L) and an image sensor (IS) is provided. The plenoptic imaging device (2) further comprises a color filter element (CFE) arranged in an aperture stop plane of the main lens (L), said color filter element (CFE) comprising at least two different color filters.
Claims15
A plenoptic imaging device comprising a micro-lens array placed between a main lens and an image sensor, the image sensor comprising a plurality of rows and columns of pixels, the plenoptic imaging device further comprising a color filter element arranged in an aperture stop plane of the main lens, the color filter element comprising at least two different color filters, each microlens imaging the color filter element on a number of rows and columns of the image sensor, wherein the plenoptic imaging device comprises an apparatus for obtaining a raw plenoptic image of a scene, the apparatus comprising a processor configured to:
- acquire a set of intermediate plenoptic images in different configurations of the color filter element, the color filter associated with a given pixel of the image sensor being changed from a current to a following configuration;
- obtain the raw plenoptic image by combining the set of intermediate plenoptic images;
- and
- generate at least one view of the scene by grouping the pixels of the raw plenoptic image that belong to the view.
A method for obtaining a raw plenoptic image of a scene, wherein the method is implemented by a plenoptic imaging device comprising a micro-lens array placed between a main lens and an image sensor, the image sensor comprising a plurality of rows and columns of pixels, and a color filter element arranged in an aperture stop plane of the main lens, the color filter element comprising at least two different color filters, each microlens imaging the color filter element on a number of rows and columns of the image sensor, and wherein the method comprises:
- acquiring a set of intermediate plenoptic images in different configurations of the color filter element, in which the color filter associated with a given pixel of the image sensor is changed from a current to a following configuration;
- obtaining the raw plenoptic image by combining the set of intermediate plenoptic images;
- generating at least one view of the scene by grouping the pixels of the raw plenoptic image that belong to the view.
