Abstract:
1. A method of displaying an image recorded by a digital camera system with a predetermined orientation, said method comprising: providing a first accelerometer integrated on a monolithic chip in the digital camera system, the first accelerometer being sensitive to acceleration in a first direction, said first accelerometer being adapted to provide a first output signal in response to acceleration in the first direction; providing a second accelerometer integrated on a monolithic chip in the digital camera system, the second accelerometer being sensitive to acceleration in a second direction different from the first direction, said second accelerometer being adapted to provide a second output signal in response to acceleration in the second direction; low-pass filtering the first and second output signals to obtain information relating to static accelerations; using the information relating to static accelerations to obtain information identifying a roll angle of the recorded image; and using the roll angle information to determine an orientation by which the recorded image is to be displayed, the orientation comprises portrait and landscape orientations, where said determining the orientation by which the recorded image is to be displayed comprises using hysteresis on the roll angle identification to prevent unintended switching between the portrait orientation and the landscape orientation.
