In this paper, we propose a new method to synthesize an integral photography image to be displayed on a flat panel display based on a raw image captured using a commercial light field camera.Among stereoscopic image display methods, Lippmann's integral photography has the advantage of producing a high sense of reality because parallax occurs in the horizontal and vertical directions.When a stereoscopic image for IP is produced via live action, a large-scale camera system is typically required.By contrast, a commercial light field camera is portable and can record the intensity and direction of incident light by stacking a microlens array on a high-definition image sensor.However, a raw image obtained from the light field camera cannot be directly used for IP.We solve this problem by introducing conversion between IP images.We develop an experimental system for synthesizing images for IP from a raw image captured using a commercial light field camera (Lytro A1).Results confirm that an autostereoscopic image with horizontal and vertical parallax is displayed when observing the image using a fly's eye lens on a PC screen.The amount of popping out or sinking can be controlled by changing the parameters of the program.
