A system and method are disclosed for reducing vibration from a camera cooling fan and thereby preserving high image quality. The system uses one or more accelerometers to provide feedback on vibration intensity and frequency that are used as input to control the fan. The fan may be switched at variable speed by a controller receiving inputs from a temperature sensor. The accelerometer(s) would measure the vibration in the camera structure at important locations such as the camera lens that would be sent to a computer or processor connected to the fan controller. The system would extract the vibration characteristics to identify speeds at which vibration is at a minimum. If the camera were too hot, the fan control loop could speed the fan up and find a local vibration minimum that would still keep the camera cool. The system uses inexpensive sensor inputs to improve image quality in cameras.
