Abstract (in Japanese) (See Japanese page) 
(in English) Recently, it has been shown that it is possible to realize a
higher-resolution image by superimposing multiple low-resolution
images projected by different projectors. In our previous study, we pointed out several peculiar properties with the images realized by this superimposed projection based on theoretical analyses. For example, the quality of the realized images depends on the brightness structure and the overall brightness of a target image. In this paper, we show that they hold in the case of real systems by constructing a working system of superimposed projection and conducting experiments. Furthermore, we present a novel method for the calibration of the system, which is based on phase shifting that is widely used in 3D shape reconstruction. We then show that the method is superior to conventional methods in terms of calibration accuracy.
