A disclosed apparatus includes a plurality of camera units. Control logic, operatively coupled to each camera unit, is operative to perform a parallax operation using at least two image frames from at least two camera units to determine a common focus distance, subsequent to completing independent auto-focus operations and respective lens position adjustments for the at least two camera units. The control logic provides a control signal to at least one of the camera units to adjust its actuator to adjust lens position in response to the determined common focus distance. A test procedure is used to map focus distance to lens position for each camera unit and to generate a lookup table. The control logic uses the lookup table unique to each camera unit to adjust the lens settings according to the determined common focus distance. The parallax operation is iterated until the common focus distance converges.

Multiple camera apparatus and method for synchronized autofocus

A method, system, and computer program product for generating a three-dimensional image from a captured two-dimensional image. The method includes capturing, via a wide-angle camera sensor of an image capturing device, a two-dimensional image of a scene. The method further includes determining depth information of the scene. The method further includes generating, from the depth information, a depth map that depicts a depth of the scene in a third dimension. The method further includes generating a wide-angle three-dimensional image by merging the depth map and the two-dimensional image.

Creating a three-dimensional image via a wide-angle camera sensor

An apparatus includes a plurality of camera units where each camera unit has a lens, a sensor that can detect at least three colors, and camera unit calibration data for each camera unit is stored in non-volatile, non-transitory memory. The apparatus also includes multi-camera auto white balance synchronization logic that is operatively coupled to each camera unit. The multi-camera auto white balance synchronization logic is operative to determine common white balance results based on the camera unit white balance results per frame and the camera calibration data. The common white balance results are provided to image signal processing pipelines such that a merged frame can be obtained by combining the frames of each camera after performing white balance and color correction using the common white balance results.
