Abstract: A projection display apparatus (100) has an image light generating unit (200), a projection optical unit (300) and a screen (220). The projection optical unit (300) has a reflection mirror (320). The screen (220) is switchably configured to as to switch to whether to diffuse image light reflected by the reflection mirror (320) or to transmit the image light reflected by the reflection mirror (320).

Abstract: A projection display apparatus (100) includes a image light generation unit (200) and a projection optical unit (300). The projection optical unit (300) has a reflecting mirror (320). The projection optical unit (300) is configured to project image light in a plurality of directions without changing the disposition of the projection display apparatus (100).

Abstract: An optical pickup device having a lens through which light transmits, a holder to which the lens is mounted, a position adjusting member which is mounted on the holder, and a housing to which the holder is mounted has a structure to allow adjustment of a mounting position of a lens assembly formed by mounting the lens and the position adjusting member on the holder when the lens assembly is assembled in the housing. In this manner, the lens can be mounted to the housing with high precision.

Abstract: The projection image display apparatus includes an image light generator and a projection optics. The projection optics includes a reflection mirror. The projection image display apparatus includes a motion sensor configured to detect a person being close to a projection region and an image controller configured to control an image to be displayed on a projection region depending on a detection result from the motion sensor.

Abstract: The projection image display apparatus includes an image light generator and a projection optics. The projection optics includes a reflection mirror. The projection image display apparatus includes an image capture device configured to capture an image of a user facing the projection surface, a first acquisition unit configured to acquire captured image data from the image capture device, a second acquisition unit configured to acquire sample data independently of the captured image data, and an image controller configured to control an image to be displayed on the projection surface on the basis of the captured image data and the sample data.
