Abstract
An imaging system is disclosed. In a cycle, two or three consecutive pairs of first sub-images and second sub-images are captured using a first image sensor and a second image sensor respectively, while wobulators are controlled to perform, during the cycle, one or two first sub-pixel shifts and one or two second sub-pixel shifts, respectively. A given first sub-pixel shift is performed in first direction, while a given second sub-pixel shift is performed in a second direction different from the first direction The first sub-images and the second sub-images of the cycle are processed, to generate a first image and a second image, respectively.
Claims15
An imaging system comprising:
- a first image sensor and a second image sensor, forming a stereo pair;
- a first wobulator and a second wobulator that are to be employed to perform sub-pixel shifts when capturing images with the first image sensor and the second image sensor, respectively;
- and
- at least one processor configured to:
- obtain, in a cycle, two or three consecutive pairs of first sub-images and second sub-images from the first image sensor and the second image sensor, respectively;
- control the first wobulator and the second wobulator to perform, during said cycle, one or two first sub-pixel shifts and one or two second sub-pixel shifts, respectively, wherein a given first sub-pixel shift is performed in a first direction, while a given second sub-pixel shift is performed in a second direction that is different from the first direction;
- and
- process the first sub-images and the second sub-images of said cycle, to generate a first image and a second image, respectively.
A method comprising:
- obtaining, in a cycle, two or three consecutive pairs of first sub-images and second sub-images from a first image sensor and a second image sensor, respectively, wherein the first image sensor and the second image sensor form a stereo pair;
- controlling a first wobulator and a second wobulator to perform one or two first sub-pixel shifts and one or two second sub-pixel shifts when capturing the first sub-images and the second sub-images during said cycle, respectively, wherein a given first sub-pixel shift is performed in a first direction, while a given second sub-pixel shift is performed in a second direction that is different from the first direction;
- and
- processing the first sub-images and the second sub-images of said cycle, to generate a first image and a second image, respectively.
