“…Color-formation methods involve time sharing and spatial formation [2], 3D display technology has shutter and polarized type, and the light source module usually includes a light-emitting diode (LED) and a laser diode (LD). To date, the color breakup from the timesharing method has been known to cause visual fatigue in the human eye according to [3][4][5][6][7][8][9], and it is common for 3D displays to make people feel tired. Therefore, the main focus of this research is to investigate the degree of visual fatigue based on various displays.…”

Different levels of visual fatigue in the human eye depend on different color-formation methods and image quality. This paper uses the high-frequency component of the spectral power of accommodative microfluctuations as a major objective indicator for analyzing the effects of visual fatigue based on various displays, such as color-formation displays and 3D displays. Also, a questionnaire is used as a subjective indicator. The results are that 3D videos cause greater visual fatigue than 2D videos (p<0.001), the shutter-type 3D display causes visual fatigue more than the polarized type (p=0.012), the display of the time-sharing method causes greater visual fatigue than the spatial-formation method (p=0.008), and there is no significance between various light source modules of displays (p=0.162). In general, people with normal color discrimination have more visual fatigue than those with good color discrimination (p<0.001). Therefore, this paper uses the high-frequency component of accommodative microfluctuations to evaluate the physiological stress or strain by overexerting the visual system, and can compare the level of visual fatigue between various displays.

“…This can yield the visual impression that colors in a moving object are spatially misaligned, a phenomenon called color breakup [23][24][25]. Color breakup occurs when colors are presented sequentially (as in single-chip DLP projectors [26,27]). Color interlacing differs from conventional color-sequential presentation by showing different color components to the two eyes at each moment in time.…”

Temporal interlacing is a method for presenting stereoscopic 3D content whereby the two eyes' views are presented at different times and optical filtering selectively delivers the appropriate view to each eye. This approach is prone to distortions in perceived depth because the visual system can interpret the temporal delay between binocular views as spatial disparity. We propose a novel color-interlacing display protocol that reverses the order of binocular presentation for the green primary but maintains the order for the red and blue primaries: During the first subframe, the left eye sees the green component of the left-eye view and the right eye sees the red and blue components of the right-eye view, and vice versa during the second sub-frame. The proposed method distributes the luminance of each eye's view more evenly over time. Because disparity estimation is based primarily on luminance information, a more even distribution of luminance over time should reduce depth distortion. We conducted a psychophysical experiment to test these expectations and indeed found that less depth distortion occurs with color interlacing than temporal interlacing.

“…This 'rainbow effect' is well-known to display researchers who wish to remove or reduce it ( [29], [15], [30], [41], [13], [28], [22]). Many researchers even remove the color wheel to increase the projector contrast in their experiments ( [19], [4]).…”

Exploiting DLP Illumination Dithering for Reconstruction and Photography of High-Speed Scenes

2011

In this work, we recover fast moving scenes by exploiting the high-speed illumination "dithering" of cheap and easily available digital light processing (DLP) projectors. We first show how to reverse-engineer the temporal dithering for off-the-shelf projectors, using a high-speed camera. DLP dithering can produce temporal patterns commonly used in active vision techniques. Since the dithering occurs at a very high framerate, such illumination-based methods can be "sped up" for fast scenes. We demonstrate this with three applications, each of which only requires a single slide to be displayed by the DLP projector. The quality of the result is determined by the camera frame-rate available to the user. Pairing a high-speed camera and a DLP projector, we demonstrate structured light reconstruction at 100Hz. With the same camera and three or more DLP projectors, we show photometric stereo and demultiplexing applications at 300Hz. Finally, with a real-time (60 Hz) or still camera, we show that DLP illumination acts as a very fast flash, allowing strobe photography of high-speed scenes. We discuss, in depth, some characteristics of the temporal dithering with a case study of This is an extension and consolidation of our previous work on the active vision systems using DLP projectors ([24], [16]
