  • Although Current market available digital photo frame products can judge whether a photo is erect or transverse when the photo is displayed and rotate the photo automatically. But, because the photo frame cannot be rotated and the length to width ratio of the photo is not changed, when an erect photo is displayed on transverse photo frame, parts of space at both left and right sides of a display panel will not be used and be wasted; and when a transverse photo is displayed on an erect photo frame, parts of space at both upper and lower sides of a display panel can also not be completely used.
    • SUMMARY OF THE INVENTION

  • For attaining to the objects mentioned above, the present invention proposes an autorotative digital photo frame, adapted to allow the digital photo frame to be adjusted automatically to the same direction as a photo, comprising:
  • a base, an inner part thereof being connected to a circuit board and a stepper motor; a microprocessor being disposed in the circuit board; the microprocessor being electrically connected to the stepper motor;
    a photo frame, provided with a framework and a display panel, a back surface of the framework being connected to a rotating shaft of the motor;
    the photo frame being electrically connected to the microprocessor;
    wherein, the microprocessor controls the stepper motor to drive the photo frame to rotate through the difference that picture data processed thereby is a transverse photo or a erect photo to allow the photo frame to be transversely or erectly disposed corresponding to the transverse photo or erect photo so as to display the transverse photo on the display panel in a transverse direction and the erect photo on the display panel in an erect direction to allow every photo can fully utilize the space of the display panel of the photo frame and is enlarged to the size closest to the display panel to enable a user to obtain the best visual effect.
