1. An electronic device comprising:
a projector configured to produce light that includes an image having a central region of pixels and a peripheral region of pixels;
a waveguide;
a lens configured to direct the light towards the waveguide; and
an input coupler configured to couple the light into the waveguide, wherein the waveguide is configured to propagate the light via total internal reflection, the lens being configured to apply a first magnification to the pixels in the peripheral region of the image and a second magnification to the pixels in the central region of the image, wherein the first magnification is greater than the second magnification.
