Casio has revealed its first compact digital camera and integrated ‘Hybrid GPS’ with the announcement of the Exilim EX-H10HG; basically a modified Exilim EX-H10 prototype camera.
The camera has a 32bit CPU, uses three-axis accelerometer and three axis orientation sensors, this calculates how far it has traveled since it was last able to receive a signal. This allows the use of the GPS when indoors or away from the GPS transmitting signals.
The “hybrid GPS” camera does the regular geotagging with the onboard GPS, but when signal is weak, the camera realigns the location with calculated estimates from the onboard accelerometers.
