The present invention provides an image direction sensing device applied in an image capturing device, which is connected to a microprocessor in the image capturing device. The direction sensing device includes at least one variable inductor and at least one voltage detecting circuit connected to the variable inductor, wherein the inductance of the variable inductor is changed according to the angle change of the image capturing device with respect to the horizontal surface. Therefore, when the image capturing device is taking a picture with a specific angle, an electrical energy is outputted to the variable inductor. Furthermore, the voltage detecting circuit detects the energy of variable inductance, thereby determining the angle (including the rotating angle and tilted angle) of capturing corresponding to the current energy of inductance. This angle information is used to correct the shifted angle of the captured image.
