Hybrid plenoptic camera
A plenoptic camera has a moveable micro-lens array in optical registration with an image sensor. A first prime mover displaces the micro-lens array synchronized with a frame rate for the camera to obtain multi-resolution of a scene. A second prime mover displaces the image sensor to increase color sampling.
1. A plenoptic camera having a micro-lens array in optical registration with an image sensor, the micro-lens array being moveable relative to the image sensor, the plenoptic camera comprising; a first prime mover for displacing, in a synchronism manner with a frame rate of the plenoptic camera, the micro-lens array between a first position greater than f, where f represents a focal plane associated with the micro-lens array, and a second position equal to f, to obtain a multi-resolution pyramid of images.
2. The plenoptic camera according to claim 1 further including a second prime mover for displacing the image sensor.
3. The plenoptic camera according to claim 2 wherein the second prime mover comprises an electric motor.
4. The plenoptic camera according to claim 2 wherein the second prime mover displaces the image sensor by a distance such that an image subsequently captured by the image sensor contains identical information as an image captured in its prior position, but with complementary colors, thereby increasing color resolution.
5. The plenoptic camera according to claim 1 wherein the first prime mover comprises an electric motor.
6. The plenoptic camera according to claim 1 wherein the first prime mover displaces the micro-lens array in steps.
7. A method for operating a plenoptic camera having a micro-lens array in optical registration with an image sensor, comprising; displacing, in a synchronism manner with a frame rate of the plenoptic camera, the micro lens array relative to the image sensor via a first prime mover between a first position greater than f, where f represents a focal plane associated with the micro-lens array and a second position equal to f, to obtain a multi-resolution pyramid of images.
8. The method according to claim 7 further including the step of displacing the image sensor via a second prime mover.
9. The method according to claim 8 wherein the second prime mover displaces the image sensor by a distance such that an image subsequently captured by the image sensor contains identical information as an image captured in its prior position, but with complementary colors, thereby increasing color resolution.
10. The method according to claim 7 wherein the first prime mover displaces the micro-lens array in steps.
11. Non-transitory computer-readable medium comprising a computer program recorded thereon and capable of being run by a processor, including program code instructions for implementing a method for operating a plenoptic camera having a micro-lens array in optical registration with an image sensor according to claim 7 .
12. Non-transitory computer-readable medium comprising a computer program recorded thereon and capable of being run by a processor, including program code instructions for implementing a method for operating a plenoptic camera having a micro-lens array in optical registration with an image sensor according to claim 8 .
13. Non-transitory computer-readable medium comprising a computer program recorded thereon and capable of being run by a processor, including program code instructions for implementing a method for operating a plenoptic camera having a micro-lens array in optical registration with an image sensor according to claim 10 .
14. Non-transitory computer-readable medium comprising a computer program recorded thereon and capable of being run by a processor, including program code instructions for implementing a method for operating a plenoptic camera having a micro-lens array in optical registration with an image sensor according to claim 9 .
