1. An imaging apparatus, comprising: an imaging section, for obtaining through the lens image data sets and image data sets by imaging subjects; a face detecting section, for detecting faces from within the through the lens image data sets; a recording section, for recording first image data sets obtained by the imaging section that include the faces; a reference image generating section, for generating reference image data sets which are employed to generate pseudo three dimensional images from the recorded first image data sets; a comparing section, for calculating correlative values between the through the lens image data that include new faces and the reference image data to compare the two, when the new faces are detected by the face detecting section; a control section for enabling obtainment of second image data sets that include the new faces by the imaging section, when the correlative values calculated by the comparing section are greater than a predetermined value; and pseudo three dimensional image generating section, for generating pseudo three dimensional images from the second image data sets, which are obtained by the imaging section, and the first image data sets, which are recorded in the recording section.
