Dense parallax image acquisition method using single-pixel imaging for integral photography

摘要

In integral photography (IP), it is difficult to obtain three-dimensional photographs with high spatial resolution, high angular resolution, and a wide viewing angle simultaneously. Thus, we proposed a dense parallax image acquisition method using single-pixel imaging. We confirmed that parallax images can be obtained depending on the position of the photodetector. By replacing the detector to each pixel of an image sensor, a two-dimensional image with different parallaxes in each pixel can be acquired. We demonstrated the reconstruction of dense parallax images according to the pixel position of the image sensor. This method is effective in addressing the trade-off among spatial resolution, angular resolution, and a viewing angle. It can also improve the image quality in IP. (C) 2019 Optical Society of America
