1. An information processing apparatus comprising:
a memory that stores image data of an image captured by an imaging unit; and
a processor that:
processes the image data stored in the memory to detect a face orientation of a face captured in the image data, and
controls a screen brightness of a display unit based on the face orientation, wherein
the processor sets the screen brightness to a first brightness upon detecting that the face orientation is within a first angle range with respect to the imaging unit, wherein
the first angle range is defined by a first angle threshold and covers a range from zero degree to a predetermine plus or minus angle, and
the zero degree is defined as the face orientation facing a predetermined direction based on a location of the imaging unit,
the processor sets the screen brightness to a second brightness upon detecting that the face orientation is out of the first angle range, wherein
the second brightness is lower than the first brightness, and
the processor sets the screen brightness to the first brightness, regardless of whether face orientation is within the first angle range, upon detecting that the face orientation changes from a first angle to a second angle within a predetermined time period, wherein
the second angle is closer to the first angle threshold than is the first angle.
