1. Apparatus for determining image capture positions for creating a stereoscopic image of a scene, the apparatus comprising:
- at least one processor and memory configured to;
receive image data of a scene captured at a first position by the image capture device;
determine distances of predefined areas of the scene by use of focus information of image data corresponding to one or more predetermined areas of the scene;
determine one of;
a near distance defined as a distance with the smallest value, a far distance defined as a distance with the highest value, and a target distance defined as a focus distance of a target object in the scene;
calculate the stereo-base of the scene using one of near distance, far distance, and target distances;
determine a second position defined by adding the calculated stereo-base to the first position laterally to the scene;
receive image data of a scene captured when image capture device is at the second position;
utilize the image data captured at the first position and the second position to create a stereoscopic image; and
utilize one of the near distance, the far distance, and the target distance to adjust at least one stereoscopic parameter of the stereoscopic image.

Abstract
Methods, systems, and computer program products for determining a depth map in a scene are disclosed herein. According to one aspect, a method includes collecting focus statistical information for a plurality of focus windows. The method may also include determining a focal distance for each window. Further, the method may include determining near, far, and target focus distances. The method may also include calculating a stereo-base and screen plane using the focus distances.
