Abstract
According to one embodiment, an information processing apparatus includes a display unit which includes a light emitting element as a light source, a variable resistance circuit which is connected in series with the light emitting element, a resistance value control unit which changes, when a designated luminance level is lower than a predetermined luminance level, the resistance of the variable resistance circuit from a first resistance to a second resistance larger than the first resistance, and a controller adjusts the value of a driving voltage applied to the light emitting element, in accordance with the designated luminance level.

An information processing apparatus comprising:
- a display unit which includes a light emitting element as a light source;
- a variable resistance circuit which is connected in series with the light emitting element;
- a resistance value control unit which changes, when a designated luminance level is lower than a predetermined luminance level, a resistance of the variable resistance circuit from a first resistance to a second resistance, a value of the second resistance larger than a value of the first resistance;
- and
- a controller which adjusts a value of a driving voltage applied to the light emitting element, in accordance with the designated luminance level.
A luminance adjusting method of adjusting a luminance of a display unit which includes a light emitting element as a light source, a variable resistance circuit which is connected in series with the light emitting element, and a controller which adjusts a value of a driving voltage applied to the light emitting element in accordance with the designated luminance level, comprising:
- changing, when a designated luminance level is lower than a predetermined luminance level, a resistance of the variable resistance circuit from a first resistance to a second resistance, a value of the second resistance larger than a value of the first resistance.
