  • Patent number: 6597339
    Abstract: In an information processing apparatus, the power consumption can be reduced by controlling the luminance of a backlight, without degrading operability of the apparatus. In the information processing apparatus having an LCD with a backlight, a CPU alters the luminance of the backlight in accordance with a content of a process (application program) to be executed, or a display content of information on the LCD. Where it is not necessary that the display content on the LCD be presented to the user in such a way that the display content may easily and clearly viewed by the user, the luminance of the backlight is decreased to save power consumption.

  • Publication number: 20020036637
    Abstract: An information processing apparatus has a display with a light source for illumination. A table holds a monitor time for monitoring a state where an input operation is being stopped for each application program or its operating status. A screen control program measures an elapsed time from a point of time when an input operation for the application program is stopped. The screen control program determines, based on the held monitor time and the measured elapsed time, whether or not the elapsed time for the application program has reached the monitor time, and reduces brightness of the light source when the elapsed time has reached the monitor time.
