    摘要: A motionless adaptive focus stereoscopic scene capture apparatus employing tunable liquid crystal lenses is provided. The apparatus includes at least two image sensors preferably fabricated as a monolithic stereo image capture component and at least two corresponding tunable liquid crystal lenses preferably fabricated as a monolithic focus adjustment component. Using a variable focus tunable liquid crystal lens at each aperture stop provides constant magnification focus control. Controlled spatial variance of a spatially variant electric field applied to the liquid crystal of each tunable liquid crystal lens provides optical axis shift enabling registration between stereo images. A controller implements coupled auto-focusing methods employing multiple focus scores derived from at least two camera image sensors and providing multiple tunable liquid crystal lens drive signals for synchronous focus acquisition of a three dimensional scene. Wafer manufacture provides a compact stereoscopic image capture apparatus for endoscopic surgery, optical inspection and entertainment applications.

    摘要: A camera module and method for focusing a tunable lens configured to continuously vary its optical power in response to a drive signal. A drive circuit generates the drive signal so that the tunable lens performs a continuous scan of its optical power. An image sensor is configured to acquire light images passing through the tunable lens, and to convert the light images to image signals during the continuous scan. A processor is configured to generate focus scores of the acquired light images using the image signals during the continuous scan. The processor is configured to determine from the focus scores a peak focus score achieved or achievable, and to instruct the drive circuit to adjust the drive signal so that the tunable lens settles at a value of the optical power that corresponds to the peak focus score.
