Abstract

This paper shows the method to calculate a computer-generated hologram (CGH) for real scenes under natural light using a commercial light field camera, and shows the results of color reconstruction of the synthesized CGHs. The CGH calculation using light field camera is performed by converting four-dimensional light field captured with a light field camera into a complex amplitude distribution, and the converted complex amplitude distribution is propagated so as to generate an interference pattern. In color reconstruction, we calculated three CGHs with red, green and blue wavelengths and superposed reconstructed red, blue and green images to obtain reconstructed color images. We verified that color three-dimensional images were reconstructed by numerical and optical reconstructions of the synthesized CGHs.
