Two-layer light field imaging using an organic photoelectric conversion film

Abstract

In this paper, we propose a novel method for light field imaging. Previous systems are difficult to obtain multi-viewpoint images (sub-images) at the high-resolution. In order to overcome this problem, we propose a two-layer light field imaging system by using an organic photoelectric conversion film (OPCF). Our imaging system places the OPCF having the green spectral sensitivity onto the micro-lens array of the conventional light field camera. It allows us to obtain the green spectrum information at the full-resolution of the image sensor. In contrast, the other spectra information (red and blue) are coded by the optical system of the light field camera, and are recorded by the image sensor. Using the captured images, we synthesize the full-resolution sub-images. Our experiments using synthetic images demonstrate that our method outperformed other previous methods.
