A color vision characteristic detection apparatus has a storage section, a
generation section, and a presenting section. The storage section stores
a basic color chart containing portions colored in colors different from
each other. The generation section performs a predetermined conversion
processing with respect to the basic color chart to generate an adjusted
color chart for one color vision characteristic type so that it is
difficult for a person who has a visual characteristic of the one color
vision characteristic type to distinguish the adjusted color chart from
the basic color chart. The presenting section presents the basic color
chart and the adjusted color chart to a user.
