An image switching device for a vehicle includes: a reference distance determination device that determines a reference distance; and a determination device that prohibits an image display device from displaying an image captured by an on-board camera, based on a feature that a detection distance from an object to a vehicle is longer than the reference distance, and allows the image display device to display the image captured by the on-board camera, based on a feature that the detection distance is shorter than the reference distance. The reference distance determination device shortens the reference distance in a case where an absolute value of acceleration of the vehicle is a second value which is greater than a first value, compared to a case where the absolute value of acceleration of the vehicle is the first value.

Image switching device for vehicle

A second display panel having a lower luminance is combined with a first display panel having a higher luminance, forming a combined display panel. The entire surface of the combined display panel is covered with a dimming filter for ornamental purpose. Transparency of the dimming filter is enhanced in a wave-length region of the light emitted from the second panel to alleviate a brightness imbalance between the first and second panels. The transparency is enhanced also in another wave-length region corresponding to light complementary to the light emitted from the second panel, so that a color shift of the display of the first panel is avoided. Preferably, an electroluminescent display panel which emits light having a sharp peak in a specific wave-length region is used as the second panel.
