Abstract
A method for detecting horizontal orientation of the picture in a camera device, and the method includes the following steps. A plurality of orientation changes are detected in the camera device and converted to voltage signals by a gravity sensor module. The voltage signals are received by a data processing module and value of the angle in which the camera device deviated from a defined horizontal orientation is calculated. The value of the angle in which the camera device deviated from the defined horizontal orientation is received by an output module. The output module indicates how to adjust the camera device to the defined horizontal orientation.
