Display control apparatus

摘要

An image display system includes a light sensor operable to change a detection sensitivity. The light sensor outputs a signal according to an intensity of external light exerting an influence on a screen of a display apparatus and to the detection sensitivity. An illuminance acquisition part of a display control apparatus acquires illuminance by the external light based on the signal output from the light sensor. Moreover, a display adjuster adjusts a displaying state of the display apparatus in accordance with the illuminance by the external light acquired by the illuminance acquisition part. A sensitivity changer periodically alternates between a “low sensitivity” of the detection sensitivity and a “high sensitivity” of the detection sensitivity of the light sensor. Thus, even when changing significantly, the illuminance by the external light can be accurately and speedily acquired.

主权项

1. A display control apparatus that controls a display of a display apparatus, the display control apparatus comprising:
an acquisition part that acquires information about illuminance by external light on a screen of the display apparatus based on a signal output from a detector that ouputs the signal according to an intensity of the external light and a detection sensitivity of the detector; an adjuster that adjusts a displaying state of the display apparatus in accordance with the acquired information about the illuminance by the external light; and a sensitivity changer that changes the detection sensitivity of the detector to each of a plurality of set sensitivity modes that are different from one another during each of repeating time periods at regular intervals.
