We studied integral photography (IF), which creates three-dimensional
autostereoscopic images. In particular we studied the possibility of a
new method that uses a television camera to shoot directly numerous r
eal images produced by a lens array. Unlike the conventional IP method
in which the film is placed immediately behind a lens array, this met
hod employs a television camera, which enables us to shoot moving pict
ures. Of a number of factors affecting the process of image pickup, we
examined some optical factors and compared them with those obtained b
y the conventional IP method. The results show that with this new dire
ct pickup method that uses a television camera, we can obtain an IP im
age like those obtained by using the conventional IP method. Further,
we conducted an experiment with an high-definition TV camera, confirmi
ng the production of an autostereoscopic image by using a display devi
ce that combines a liquid-crystal panel and pinholes. (C) 1997 Optical
