An image display unit, such as a projection-type image display apparatus, displays a first image and a second image, having a predetermined parallax relative to the first image, onto a predetermined display region by dividing the first image and the second image temporally or spatially. First eyeglasses are to be worn by a first viewer to see the first image and the second image displayed on the display region. Second eyeglasses are to be worn by a second viewer to see the first image and the second image displayed on the display region, and the second viewer faces the first viewer in a direction parallel to the plane of display. The first eyeglasses perform a function of having the right eye of the first viewer see the first image and having the left eye of the first viewer see the second image. The second eyeglasses perform a function of having the right eye of the second viewer see the second image and having the left eye of the second viewer see the first image.

Stereoscopic image display system and projection-type image display apparatus

A first detection unit and a second detection unit detect the light that is incident from the direction where a screen is to be located. A controller determines whether the screen is located at a recommended position based on output signals from the first detection unit and the second detection unit. When the screen is located at the recommended position, the controller controls the projection display apparatus so as to be in the state where a significant image can be projected. The controller may determine whether the screen is located at the recommended position and in a normal state based on the output signals. When the screen is located at the recommended position and in a normal state, the controller may control the projection display apparatus so as to be in the state where a significant image can be projected.
