Abstract
An imaging device includes a focusing element, an image sensor, and an actuator configured to translate at least one of the image sensor and the focusing element relative to each other. A controller of the imaging device is configured to use the image sensor to capture an image frame including at least a portion of the image of the object, determine a current position of the image of the object in the image frame, determine a deviation of the current position from a target position of the image of the object in the image frame, and operate the actuator to reduce the deviation. In this manner, the image of the object may be brought to a center of a captured image frame. Such an imaging device may be used as a self-aligning eye-tracking camera in a near-eye display.
