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).
