1. An imaging system comprising:
a first camera and a second camera corresponding to a first eye and a second eye of a user, respectively; and
at least one processor configured to:
control the first camera and the second camera to capture a sequence of first images and a sequence of second images of a real-world environment, respectively; and
apply a first extended depth-of-field correction to one of a given first image and a given second image by utilising a first neural network that corrects first point spread functions at a focussing distance range of 10 centimetres to M, the first point spread functions correspond to a given camera that captured the one of the given first image and the given second image, M lying in a range of 30 centimetres to 100 centimetres, whilst applying at least one of: defocus blur correction, image sharpening, contrast enhancement, edge enhancement to another of the given first image and the given second image;
obtain information indicative of a dominant eye of the user or determine the dominant eye from amongst the first eye and the second eye; and
apply a second extended depth-of-field correction to the another of the given first image and the given second image by utilising a second neural network that corrects second point spread functions at a focussing distance range of N to infinity, N lying in a range of 30 centimetres to 100 centimetres, the second point spread functions correspond to another given camera that captured the another of the given first image and the given second image, wherein the another given camera corresponds to the dominant eye of the user.
