Abstract: Electronic devices, methods, and program storage devices for achieving improved optical character recognition (OCR) operations are disclosed. Performing OCR operations on captured images, e.g., images captured by cameras that are affixed to a user's body (e.g., from mixed reality devices, such as smart HMDs) requires a low-power, robust camera design. Obtaining high spatial resolution in such captured images faces many challenges. However, images with higher spatial resolution can be created by combining information extracted from multiple images captured by such devices, leveraging information obtained from positional sensors of such devices, and performing SR post-processing operations. Such higher spatial resolution images may then be used to enable high-acuity OCR capabilities. The solutions disclosed herein also compensate for the missing ability of such devices due to the lack of a vestibulo-ocular reflex (i.e., the human visual system's ability to use compensating eye movement to fixate and read text clearly, despite head movement).

Abstract: A waveguide with an input coupler and an output coupler that redirects reflected light to a camera. The waveguide may be integrated in a lens of a wearable device such as a pair of glasses. Light sources emit light beams towards the eye. A portion of the light beams are reflected by the surface of the eye towards the input coupler located in front of the eye. The input coupler may be implemented according to diffractive or reflective technologies, and may be a straight or curved line of narrow width to focus at close distances but of a length long enough to sufficiently image the eye. The input coupler changes the angles of the light beams so that the light beams are relayed using total internal reflection and focused towards an output coupler of the waveguide. The light beams are redirected by the output coupler to the camera.
