Patent number: 6556134Abstract: In display apparatus and method for an automotive vehicle, a display (2) is disposed on a position of the vehicle placed in a proximity to a dashboard surface of the vehicle and a controller (7), when a state of the vehicle which satisfies a predetermined condition is detected, executes a process to gradually reduce a brightness of an image screen of the display toward a predetermined direction which is more distant from a direction of a line of sight of a vehicular driver when the vehicular driver gazes a vehicular forward direction. In one embodiment, the controller gradually reduces the brightness of the image screen of the display toward the predetermined direction in a linear manner. The predetermined direction is, for example, directed from an upper end of the image screen to a lower end thereof.Type: GrantFiled: November 14, 2001Date of Patent: April 29, 2003Assignee: Nissan Motor Co., Ltd.Inventors: Yoshiharu Nakaji, Satoshi Kitazaki, Kazuhito Kato, Shunsuke Hijikata, Akinari Hirao
