Title: Shutter spectacles
Inventor: KIMURA MASANOBU
IPC: G02C7/12
Filed: 1988-02-23
Abstract: PURPOSE:To observe a stereoscopic image with correct colors by arranging correcting means such as magnesium group color filters having reverse spectral characteristics against the spectral characteristics of twist nematic TN liquid crystal shutters adjacently to the shutters. CONSTITUTION:A pair of right and left magnesium group color filters 8a, 8b for correcting spectral characteristics are arranged in front of a pair of right and left TN liquid crystal shutters 7a, 7b fitted to a shutter spectacles body 6. Since the spectral characteristics of the shutters 7 is deflected to a green group in the approximate characteristics of a CRT of a color TV, the shutters 7 and the filters 8, but the filters 8 have characteristics for absorbing colors in a green range, colors in respective wavelengths can be almost uniformed in the spectral characteristics obtained by synthesizing respective spectral characteristics. Consequently, colors reproduced on the CRT are almost equal to the colors of the original image.
