Abstract
There is provided an information processing apparatus including a display portion, an illuminance sensor and a controller. The display portion has a display screen. The illuminance sensor measures an ambient brightness of the display screen at a first interval. The controller shifts the illuminance sensor to a state in which the illuminance sensor measures the ambient brightness at a second interval which is longer than the first interval when a change of the brightness is relatively small.
Claims11
An information processing apparatus comprising:
- a display portion including a display screen;
- an illuminance sensor configured to measure an ambient brightness of the display screen at a first interval;
- and
- a controller communicatively coupled to the illumination sensor, the controller being configured to shift the illuminance sensor to a state in which the illuminance sensor measures the ambient brightness at a second interval which is longer than the first interval when the ambient brightness exceeds a prescribed illuminance value,
- wherein the illuminance sensor to store an illuminance value representative of the ambient brightness within a buffer accessible to an operating system, the operating system being configured to access the buffer and automatically adjust the ambient brightness of the display screen based on the illuminance value.
