Document Type and Number:
WIPO Patent Application WO/2019/017048
Kind Code:
A1
Abstract:
Provided are a projection type display device, a projection type display device control method, and a projection type display device control program that maintain a constant display quality regardless of the condition of a window, and can prevent an increase in manufacturing cost. An HUD 4, which is installed in construction machinery 100 having a window 6 that rotates to open in an operator cab 10A, comprises: a first projection display unit 2 and a second projection display unit 3 that are positioned in different locations within the operator cab 10A, spatially modulate light on the basis of image information, said light being emitted from a light source, and project spatially modulated image light onto the window 6 to display a virtual image that is based on this image light; and a control unit 80 that receives the rotation amount of the window 6, and on the basis of the received rotation amount, causes the image light to be projected onto the window 6 from either the first projection display unit 2 or the second projection display unit 3.
