IMAGE DATA OBTAINING METHOD AND APPARATUS THEREFOR

摘要

An image data obtaining method to obtain three-dimensional (3D) image data by using a plurality of pieces of two-dimensional (2D) image data obtained by capturing an image of a scene, the image data obtaining method including: setting a focal length of an image-capturing device so as to allow a reference component, from among a plurality of components of the scene, to be focused; obtaining the plurality of pieces of 2D image data by using different aperture values in the image-capturing device having the set focal length; and obtaining the 3D image data by using a relation between the plurality of pieces of 2D image data.
