PROBLEM TO BE SOLVED: To provide an on-vehicle display device not providing uncomfortable feeling to an observer even if the positional relation of the display device and the observer changes. SOLUTION: This on-vehicle display device 100 measures the body pressure of occupants in the seated state of the occupants, retrieves a body database part 103 to estimate the physical constitutions and seated postures of the occupants, and selects a body vibration transmission function. By using the body vibration transmission function and the detection data on the motion of a vehicle, the estimated values of the motions of the head parts (particularly eye balls) of the occupants are calculated. By using the detection data indicating the motion of the vehicle, the movement amount of an image display part 108 in the pitch direction is calculated. By using the estimated position of the eye balls and the position of the image display part 108, the relative displacement thereof is obtained. The displayed position of an image displayed in the image display part 108 is moved so as to cancel the movement amount of the image display part 108 and the movement of the displayed image resulting from the relative displacement. Thus, the display image is viewed for the occupants to be stopped in a space. COPYRIGHT: (C)2004,JPO&NCIPI
