On-eye image processing

Abstract

An eye-mounted device includes a contact lens that contains a femtoimager and corresponding femtoprojector. The femtoimager captures images of a user's surrounding environment. Images captured by the femtoimager are transmitted to the femtoprojector via a signal path containing digital image processing circuitry to perform one or more image processing functions on the captured images. The image processing circuitry comprises a plurality of filters connected in series and/or parallel that are configurable to implement different types of image processing, depending on the content of the images captured by the femtoimager. Compute approximation and simplification is utilized to reduce the power consumption within the lens. Components outside the contact lens determine the type of image processing, thus reducing power consumption within the contact lens. The femtoprojector then projects the resulting images to the user's retina.
