Projection type display device, control method of projection type display device, control program of projection type display device

摘要

PROBLEM TO BE SOLVED: To provide a projection type display device, a control method of the projection type display device, and a control program of the projection type display device capable of supporting safe driving of a vehicle. A HUD1 spatially modulates the light emitted from a light source based on image information, and projects the spatially modulated image light onto projection surfaces 5A, 6A, 7A, and projection display units 20U, 30U, 40U. It includes a control unit 60 that controls projection display units 20U, 30U, and 40U based on the line of sight of the driver. The control unit 60 performs line-of-sight tracking control for projecting image light from a projection display unit that projects an image light on a projection surface that intersects the driver's line of sight, and further, the driver's line of sight is one of the projection surfaces. When the state changes from the state where it intersects with the first projection surface to the state where it intersects with the second projection surface, which is one of the projection surfaces, it depends on the line-of-sight tracking control and the projection display unit that targets the first projection surface as the image light projection target. Performs projection continuation control to continue the projection of image light. [Selection diagram] FIG. 10
