Abstract
Provided is a head-mounted video presentation device which has a visible light wavelength conversion and is designed for a user having degraded sensitivity to a first wavelength band as a part of a visible light wavelength band as compared with a second wavelength band as the remaining part of the visible light wavelength band. A head-mounted video presentation device for a user having degraded sensitivity to a first wavelength band as a part of a visible light wavelength band as compared with a second wavelength band as the remaining part of the visible light wavelength band includes: an imaging unit for taking a video in a viewing direction of the user to acquire first video information; a wavelength conversion unit for converting at least a part of a color signal for at least the first wavelength band in the first video information into a color signal expressing colors in the second wavelength band, and outputting second video information based on the converted color signal; and a video presentation unit for presenting, based on the second video information, a wavelength-converted video in the viewing direction of the user, to the user.
