1. 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.
