DISPLAY CONTROL APPARATUS FOR VEHICLE
First Claim
1. A display apparatus for a vehicle comprising:
- an illuminance sensor having a first illuminance sensor and a second illuminance sensor, wherein the first illuminance sensor acquires illuminance of environmental light outside the vehicle, and the second illuminance acquires illuminance of environmental light inside the vehicle;
an image presentation unit that selects either the first illuminance sensor or the second illuminance sensor, based a comparison result, and that projects an image display light by controlling luminance of the image display light, generated from an image signal of an image to be displayed, based on the illuminance of environmental light acquired by the selected luminance sensor, wherein the comparison result indicates a magnitude relation between a predetermined illuminance sensor selection reference threshold value, based on which to select either the first illuminance sensor or the second illuminance sensor, and the illuminance of environmental light outside the vehicle acquired by the first illuminance sensor; and
a combiner onto which the image display light is projected,wherein the image presentation unit is mountable to a rear-view mirror of the vehicle, andwherein, when the image presentation unit is mounted to the rear-view mirror thereof, the illuminance sensor is arranged such that a position of the illuminance sensor along a longitudinal direction of the rear-view mirror lies within a range of width of the longitudinal direction thereof.

Abstract
A first illuminance sensor acquires the illuminance of environmental light outside a vehicle, and a second illuminance sensor acquires the illuminance of environmental light inside the vehicle. An image presentation unit controls the luminance of image display light generated from image signals of an image to be displayed, based on the luminance of environmental light acquired by the first illuminance sensor or the second illuminance sensor, and projects the image display light. The image presentation unit selects either the first illuminance sensor or the second illuminance sensor, based on a comparison result, which indicates a magnitude relation between the illuminance of environment light outside the vehicle acquired by the first illuminance sensor and an illuminance to be compared. And the image presentation unit controls the luminance of image display light, based on the illuminance of environmental light acquired by the selected illuminance sensor.
