摘要： A head-up display device (HUD) 1 includes a sound analysis portion 42 that determines whether a specific alarm is involved in sound signals from microphones 40a to 40d to collect ambient sound around a vehicle 2. When a specific alarm has been detected as determined by the sound analysis portion 42, an image display unit 30 displays icons 91, 92 representing the specific alarm. The specific alarm includes a siren sound given from an emergency vehicle and a horn sound given from a general vehicle and the sound analysis portion 42 analyzes frequency of input sound signals and thereby determines whether the sound is the specific alarm.
