Stereoscopy is a method of recording details of 3D objects for imaging by mimicking the work of the eyes. Two eyes perceive two images from two different angles with a small visual difference due to the difference in eyes’ locations, and then the brain merges the two images into a 3D image useful in evaluating the depths of objects in the picture. Integral imaging is an auto-stereoscopic or a multi-subject 3D view. It views the 3D image on behalf of the viewer without special glasses by placing an array of micro-lenses in front of the image, where each lens varies depending on its viewing angle. (Arimoto and Javidi 2001).

Naked-eye three-dimensional (3D) display technology is regarded as the next-generation displays’ key technology that will redefine portable electronics, attracting academic, medical, and industrial attention for its realistic visual expertise with further depth estimation [1–3]. To obtain ideal 3D utility, high-quality 3D images should be projected to many viewpoints with smooth motion parallax over a large viewing angle, thus discretizing the target scene into spaced views to produce stereoscopic expertise for several observers simultaneously. However, restricted by state-of-the-art display information, the depth of field, resolution, and viewing angle has become essential trade-offs in 3D displays. Integral imaging (II), which was first proposed by Nobel laureate G. Lippmann with his invention of integral photography in 1908, is considered the mainstream technical solution because it can construct the light field of the 3D scene and provide full parallaxes, quasi-continuous viewing points, and numerous physiological depth cues [4–6]. However, some disadvantages need to be solved before its commercialisation, such as the pseudoscopic issue and the 2D/3D convertible issue.
