Imaging system and method of producing context and focus images

An imaging system comprising:

• at least one imaging sensor per eye of a user;
• and
• a processor coupled to the at least one imaging sensor, the processor being configured to control the at least one imaging sensor to capture at least one image of a real world environment,
• wherein the processor is arranged to be communicably coupled with a display apparatus, the display apparatus comprising:
• an optical combiner;
• means for tracking a gaze direction of the user,
• at least one context image renderer for rendering a context image of the at least one image, and
• at least one focus image renderer for rendering a focus image of the at least one image, separate from the context image,
• further wherein the processor is configured to:
• receive, from the display apparatus, information indicative of the gaze direction of the user;
• determine a region of visual accuracy of the at least one image, based upon the gaze direction of the user;
• process the at least one image to:
• generate the context image at a first resolution by binning pixels of the at least one image, and
• generate the focus image at a second resolution higher than the first resolution by demosaicing the at least one image,
• wherein, when processing the at least one image, the processor is configured to crop the at least one image to generate the focus image in a manner that the focus image substantially corresponds to the region of visual accuracy of the at least one image;
• and
• communicate the generated context image and the generated focus image to the display apparatus,
• wherein the optical combiner of the display apparatus is operable to optically combine the generated content image and the generated focus image for display to the user.
