In this paper, we propose coarse integral imaging composed of a fine interleaved Fresnel lens array. By using elemental lenses with smaller widths, the parallax between adjacent elemental images is reduced, resulting in improved image continuity. Additionally, the small parallax leads to clearer images with minimal blurring even when the images are blended by the interleaved Fresnel lens array. To address the issue of narrow viewing zone due to smaller elemental lenses, eye-tracking technology is used to follow the motion of the viewer, which enables observation of the image from a wide viewing angle. Single-pass multi-view rendering is introduced to generate a large number of small elemental images in real-time.
