Abstract
A head-up display on a vehicle, which calls the attention of the driver or passenger to a dangerous object and makes the driver or passenger reliably recognize a communicated alarm, comprises: an image display device for displaying an image taken by a camera; a detecting device for detecting a target object; a switching device for manually switching between a display state and a warm-up state; and a warning device for outputting a control signal based on the detected result, thereby making the image display device display the image. The brightness for displaying the image according to the control signal is higher than the brightness for displaying the image according to a manual operation of the switching device.
