摘要
Techniques may include synchronizing the positioning of an adjustable lens in a camera assembly with the capture of an image frame by the image sensor and optimizing the position of the adjustable lens to reduce the amount of blur caused by translation of the camera assembly along a direction along the optical axis over the course of a frame. Techniques may provide moving the lens to a plurality of optimized positions, relative to the image sensor, over the course of a frame, to reduce motion blur in an image due to translation of the camera assembly in a direction along the optical axis during the frame. Some embodiments may provide for "tight" synchronization in cases where the plurality of optimized positions are based on a time-dependent function that takes into account when each row of the image sensor is being exposed over the course of the frame.
