Abstract

An auto-focus camera determines and focuses on a region-of-interest (RoI), e.g., faces, plates of food, flowers, etc. There is a slight lag, of the order of milliseconds, between the determination of the RoI and the capture of an image. During the time period of the lag, the subject of the photograph can sometimes move out of the just-determined RoI which can cause an off-target focus. This disclosure describes techniques to predict the RoI for a frame based on the RoIs of immediately-previous frames, the camera state, machine-learned patterns of motion, etc. The techniques enable robust and accurate auto-focus on the subject during capture of the photograph.
