Abstract:
A head-up display includes a display device and a projection optical system. The projection optical system has a lens group including at least one lens element and projects onto a reflecting member an image displayed on the display device. The lens group includes a drive lens that shifts along an optical path to change its distance from the display device.

Claim (Index 1):
An image projector that projects an image onto a transmissive reflecting member to allow a viewer to visually recognize a virtual image, the image projector comprising:\n a display device that displays an image; and a projection optical system that projects onto the transmissive reflecting member the image displayed on the display device, the projection optical system including a lens group that includes at least one lens element, wherein the lens group includes at least one drive lens that shifts along an optical path to change the distance from the drive lens to the display device, and wherein the image projector satisfies the following condition (1):\n 1<\u0394 D/\u0394L \u2003\u2003(1) \n where\n \u0394 D  is 1/ Z 1\u22121/ Z 2, \n Z1 is a sight distance of a virtual image before the drive lens is shifted, Z2 is a sight distance of the virtual image after the drive lens is shifted, and \u0394L is a shift amount of the drive lens.
