title: Effects of focusing on the resolution characteristics of integral photography.
abstract: The effects of focusing on the resolution characteristics of integral photography (IP) are analyzed. First, there is an attempt to obtain the resolution characteristics of capture and display systems as the product of their modulation transfer functions (MTFs). Next, the relationship between this overall MTF and focusing during the capture is studied. The results show that, with focusing set at infinity, IP can provide three-dimensional images without remarkable resolution degradation over a wide range of depth.
