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

摘要

Provided are a projection type display device, a control method of a projection type display device, and a control program of a projection type display device, capable of being continuously used even in a case where a vehicle vibrates, and performing optimal display depending on the vibration. An HUD 100 includes a projection display section 50 that projects image light obtained by spatially modulating light emitted from a light source onto a combiner 12 to display a virtual image, a first vibration detector 61 that detects a first vibration of the combiner 12, a second vibration detector 62 that detects a second vibration of the projection display section 50, a third vibration detector 63 that detects a third vibration of the projection display section 50 with respect to the combiner 12 on the basis of the first vibration and the second vibration, and a display controller 64 that controls the image to be displayed by the projection display section 50. The display controller 64 changes a display format of content to be displayed by the projection display section 50 on the basis of the third vibration.
