A light management utility program provides a user interface for setting an angle at which a display surface of a reflection-type LCD is inclined in use relative to a line of view of a user. If the user interface has determined that the LCD is used in such a state that an upper part of the display surface is positioned backward and a lower part of the display surface is positioned forward, the light management utility program, for example, turns off those front lights arranged on the lower part, which are useless in such a condition of use. In this manner, the turn-on of front lights is properly controlled in accordance with the angle between the display surface of the LCD and the line of view of the user. Hence, the power consumption is greatly reduced.

1. Field of the Invention
The present invention relates generally to a display control apparatus and a display control method which control driving of a display device such as a reflection-type Liquid Crystal Display (LCD), and more particularly to a display control apparatus and a display control method which can properly control turn-on of a light for illuminating a display screen of the display device and can greatly reduce a power consumption of the display device.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention, and together with the general description given above and the detailed description of the embodiments given below, serve to explain the principles of the invention.
FIG. 1 shows an external appearance of an information processing apparatus according to an embodiment of the present invention;
FIG. 2 shows arrangement of front lights associated with the LCD of the information processing apparatus of the embodiment;
An embodiments of the present invention will now be described with reference to the accompanying drawings.
FIG. 1 shows an external appearance of an information processing apparatus according to the embodiment of the present invention. As is shown in FIG. 1, this information processing apparatus is a notebook-type personal computer having a cover. An LCD 5 is disposed on the inside of the cover. The LCD 5 is of a so-called reflection type. A plurality of lights (front lights) for illuminating the display surface are arranged around a peripheral portion of the LCD 5 in a distributed fashion.
A keyboard 8 and a touch panel 9 are provided on the main body that is opposed to the cover. In addition, a mouse 10 for pointing a given location on the LCD 5, like the touch pad 9, may be connected, if necessary, to the main body of the information processing apparatus.
