1. A digital photo frame comprising:
- a power jack configured for connecting to a power source;
a power management unit configured for distributing power from the power jack to the digital photo frame;
a storage unit configured for storing a plurality of digital pictures;
a display unit configured for displaying the digital pictures;
a detection unit configured for detecting whether there is a person around the digital photo frame;
a processing unit connected with the detection unit and configured for controlling the power management unit to stop providing power to the display unit and controlling a media player to play the audio file if the detection unit detects nobody around the digital photo frame in a first predetermined time period, controlling the power management unit to stop providing power to the digital photo frame if the detection unit detects nobody around the digital photo frame in a second predetermined time period, and controlling the media player to stop playing the audio file if the detection unit detects a person around the digital photo frame in the second predetermined time period.

Abstract
A digital photo frame with a function of automatically power off is provided. The digital photo frame includes a display unit, a power management unit, a storage unit, a detection unit, and a processing unit. The detection unit detects whether there is some one around the digital photo frame. The processing unit controls the power management unit to stop providing power to the display unit if the detection unit detects nobody around the digital photo frame in a first predetermined time period, and controls the power management unit to stop providing power to the digital photo frame if the detection unit detects nobody around the digital photo frame in a second predetermined time period.

2. A method of automatic powering off a digital photo frame, wherein, the digital photo frame comprises:
-
a processing unit; a power management unit; a detection unit; and a display unit; the method comprising the steps of; sending a first detection signal to the processing unit when the detection unit does not detects a person around the digital photo frame in a first predetermined time period; powering off the display unit via the power management unit controlled by the processing unit and outputting audio signals via an audio output unit controlled by the processing unit when the processing unit receives the first detection signal; sending a power-off signal to the processing unit when the detection unit does not detects a person around the digital photo frame in a second predetermined time period; powering off the digital photo frame via the power management unit controlled by the processing unit when the processing unit receives the power-off signal; sending a second detection signal to the processing unit when the detection unit detects a person around the digital photo frame in a second predetermined time period; and powering on the display unit via the power management unit controlled by the processing unit and stopping outputting the audio signals via the audio output unit controlled by the processing unit when the processing unit receives the second detection signal.
