Claim One:
1. A head-up display device comprising: a screen; a projector that projects a visual image to the screen using a projection lens; an image generator that generates a virtual image of the visual image to be visually recognized by a user from the visual image projected to the screen, wherein the visual image is composed of a first visual image and a second visual image; the image generator generates a first virtual image, which is a virtual image of the first visual image, from the first visual image, and generates a second virtual image, which is a virtual image of the second visual image, from the second visual image; and the screen is composed of a first screen to which the first visual image is projected and a second screen to which the second visual image is projected, the first screen and the second screen being disposed such that the second virtual image is generated above the first virtual image, and the first screen being fixed along an optical path of the projector; a processor that changes a distance from the first virtual image to the second virtual image, wherein the processor changes the distance from the first virtual image to the second virtual image by: making a distance from the user who visually recognizes the virtual image to the first virtual image constant; and changing a distance from the user to the second virtual image based on an object in an external environment, wherein the first visual image is a visual image for information, a generation distance from the user to a virtual image generated of which need not be changed; and the second visual image is a visual image for information, a generation distance from the user to a virtual image generated of which needs to be changed.
