Multi-projection of lenticular displays to construct a 256-view super multi-view display

Abstract

A new super multi-view (SMV) display system that enables the number of views to be increased is proposed. All three-dimensional (3D) images generated by multiple multi-view flat-panel displays are superimposed on a common screen using a multi-projection system. The viewing zones of the flat-panel 3D display are produced in the pupils of the projection lenses and then imaged to the observation space by a screen lens. Sixteen flat-panel 3D displays having 16 views were used to construct a SMV display having 256 views. The 3D resolution was 256 x 192. The screen size was 10.3 inches. The horizontal interval of the viewing zones was 1.3 mm.

Systematic characterization and optimization of 3D light field displays

“…Several different methods have been explored to implement LF-3D displays, including SMV displays [11][12][13][14][15], integral-imaging (InI) based displays [16][17][18], and computational multilayer light field displays [19,20]. Analogous to the camera array method for light field capture, an SMV display generally employs an array of 2D displays, each of which renders an elemental view of a 3D scene from a given viewpoint, to produce dense samples of the light rays apparently emitted by the scene.…”

“…The rendering plane is where the elemental images are displayed and may be considered as the source defining the positional information of the light field function. It is an abstract representation of an array of displays in SMV systems [11][12][13][14][15], or a single physical display [16] or its virtual image through an eyepiece [17,18] being spatially divided into multiple regions in the case of InIbased displays, or the modulation layer closest to the backlight in computational multi-layer displays [19], or the point source array in pinlight displays [20]. The elemental images function as spatially-incoherent objects with each representing a unique perspective of a 3D scene.…”

“…The modulation plane is where the directional samples of the light rays are produced and may be considered as the component defining the directional information of the light field function. It is an abstract representation of an array of optics [11][12][13][14][15], a lenslet array [16,17], an aperture array [18], or SLM(s) [19,20] in the different LF-3D display methods above. In SMV and InI-based LF-3D displays, the modulation plane consists of an array of optical elements (e.g.…”

“…The conventional S3D displays fail to render correct retinal blur effects and stimulate natural eye accommodation response, which causes several cue conflicts and is considered as one of the key contributing factors to various visual artifacts associated with viewing S3D displays, such as distorted depth perception [3] and visual discomfort [4]. In recent years, several display methods that are potentially capable of resolving the VAC problem have been demonstrated, including holographic displays [5], volumetric displays [6,7], multi-focal plane displays [8][9][10] and light field displays [11][12][13][14][15][16][17][18][19][20]. Among these different methods, the light field display method is considered as one of the most promising 3D display techniques.…”
