Disclosed herein are cameras and image sensors, and electronic devices containing them, having pixel arrays operable both for obtaining images and detecting flicker in ambient light. For flicker detection, such as prior to image capture, light-generated current from a set of pixels of the pixel array is received at a transimpedance amplifier (TIA) that is formed in a common semiconductor substrate with the pixel array. An output signal of the TIA is digitized and signal processed to detect the flicker in the ambient light. Also disclosed are image sensors having pixel arrays with an embedded modulated light source. The modulated light source may be used for proximity detection, either by time-of-flight or intensity variation of reflected light.

Flicker and proximity detection in image sensors with embedded low power readout circuitry

A small imager mounted on a user's eye (referred to as a femtoimager) is coordinated with an external camera. The femtoimager may be contained in a contact lens, and it may be aligned with the gaze a user's eye. The femtoimager and external camera capture images with overlapping views of the external environment. Images from the two imagers may be compared with one another to estimate the femtoimager's view of the external environment relative to the camera's view of the external environment. This may then be used for different applications.

Coordinating an eye-mounted imager with an external camera

A scleral contact lens has a core containing an optical filter. The core and/or the optical filter may comprise oxygen impermeable material, such that an overall oxygen permeability of the core is insufficient to oxygenate a user's cornea when wearing the contact lens. To provide oxygenation to the user's cornea, the contact lens further comprises an outer covering, and an inner covering, each corresponding to a thin layer of gas-permeable material shaped to form a respective manifold between the covering and the core. Oxygen from an outside environment passes through the outer covering to reach the outer manifold, through an air path formed within the core to the inner manifold, and through the inner covering to reach the cornea of the user's eye.
