Integral photography (IP) is a technique for creating 3 D images that can be seen from any viewing point without the aid of special viewing glasses. In ordinary 2 D imaging systems, if the camera is focused on a specific subject. other subjects which around it are out of focus, lowers the resolution of the picture. For IP, subjects that are widely distributed in the depth direction must be reproduced with high resolution. Detailed studies have not been made on filming. First. the Characteristics of resolution by the product of their modulation transfer functions (overall MTF) is evaluated. Next, the relationship between the overall MTF at the Nyquist frequency for IP and how the pickup system is focused on the subject is clarified. It is found that by focusing on the observer or at infinity, constant responses can be gained for the reconstructed images whose original subjects are widely distributed towards depth direction.
