“…The saturations of the primaries of light emitting diode (LED) displays and organic light emitting diode (OLED) displays are high because the spectral widths of their primaries are narrower comparing with the cathode ray tube (CRT) displays, plasma displays, and liquid crystal displays. Further expanding color gamut can be realized by adding more primaries [1][2][3][4][5]. The display with more than three primaries is usually called multi-primary display.…”

“…From a spectroscopic viewpoint, in the multispectral image, we obtain a spectrum in each pixel. Multispectral imaging provides more than color information while avoiding the metamerism 1 and unlike conventional digital cameras, it is not limited to the visual range, rather it can also be used in near infrared, infrared and ultraviolet spectrum as well. [2][3][4][5] It can significantly improve the color accuracy [6][7][8][9][10] and makes color reproduction under different illumination environments possible with reasonably good accuracy.…”

Multispectral color imaging is a promising technology, which can solve many of the problems of traditional RGB color imaging. However, it still lacks widespread and general use because of its limitations. State of the art multispectral imaging systems need multiple shots making it not only slower but also incapable of capturing scenes in motion. Moreover, the systems are mostly costly and complex to operate. The purpose of the work described in this paper is to propose a one-shot six-channel multispectral color image acquisition system using a stereo camera or a pair of cameras in a stereoscopic configuration, and a pair of optical filters. The best pair of filters is selected from among readily available filters such that they modify the sensitivities of the two cameras in such a way that they get spread reasonably well throughout the visible spectrum and gives optimal reconstruction of spectral reflectance and/or color. As the cameras are in a stereoscopic configuration, the system is capable of acquiring 3D images as well, and stereo matching algorithms provide a solution to the image alignment problem. Thus the system can be used as a "two-in-one" multispectral-stereo system. However, this paper mainly focuses on the multispectral part. Both simulations and experiments have shown that the proposed system performs well spectrally and colorimetrically.

This article presents a compact multi-spectral lens array and describes its application in assisting color-blindness. The lens array consists of 9 microlens, and each microlens is coated with a different color filter. Thus, it can capture different light bands, including red, orange, yellow, green, cyan, blue, violet, near-infrared, and the entire visible band. First, the fabrication process is described in detail. Second, an imaging system is setup and a color blindness testing card is selected as the sample. By the system, the vision results of normal people and color blindness can be captured simultaneously. Based on the imaging results, it is possible to be used for helping color-blindness to recover normal vision.
