Claim Text:
1. A method for operating an imaging system having a stacked-chip image sensor and an adjustable lens system to capture an image of an object in a scene, wherein the stacked-chip image sensor comprises a planar array of image pixels and storage and processing circuitry, the method comprising: moving at least one lens in the adjustable lens system into a plurality of focus positions while passing light from a scene to the image pixels through the at least one lens; with the image pixels, capturing a focus bracket of image frames while moving the at least one lens; with the storage and processing circuitry, gathering depth map information for the scene by comparing a first image frame in the focus bracket with a second image frame in the focus bracket, wherein gathering the depth map information comprises determining a distance between the object in the scene and the imaging system; and with the storage and processing circuitry, combining a set of image frames from the focus bracket of image frames to generate a focused image based on the gathered depth map information.
