Abstract
An image display apparatus includes a display section that displays an image on a display surface, an output section that outputs light, a changer that changes the angle of the light outputted from the output section with respect to the display surface, a position detector that detects a reflected position where the light outputted by the output section is reflected, and a change controller that controls the changer based on the result of the detection performed by the position detector.
Claims7
An image display apparatus comprising:
- a display section that displays an image on a display surface;
- an output section that outputs light;
- a changer that changes an angle of the light outputted from the output section with respect to the display surface, wherein the changer includes a drive section and an adjustment mechanism that changes the angle in accordance with a drive action of the drive section;
- a position detector that detects a reflected position where the light outputted by the output section is reflected directly on the display surface, and outputs a result of the detection of the reflected position;
- and
- a change controller that controls the changer based on the result of the detection of the reflected position outputted by the position detector, wherein the change controller controls the drive action of the drive section based on the reflected position detected by the position detector and a target position on a side opposite the output section with respect to the image on the display surface, wherein
- the change controller evaluates, based on the result of the detection of the reflected position, whether or not the reflected position coincides with the target position, and
- when the position detector does not detect, as the reflected position, the target position, the change controller determines, based on a relationship between an amount of the drive action of the drive section and an amount of movement of the reflected position, a target drive amount that allows the reflected position to move to the target position, and the change controller drives the drive section by the target drive amount.
A method for controlling an image display apparatus including a display section that displays an image on a display surface, an output section that outputs light, and a changer that changes an angle of the light outputted from the output section with respect to the display surface, the method comprising:
- outputting light;
- detecting a reflected position where the light outputted is reflected directly on the display surface, and outputting a result of the detection of the reflected position;
- controlling the changer based on the outputted result of the detection of the reflected position, wherein the changer includes a drive section and an adjustment mechanism that changes the angle in accordance with a drive action of the drive section;
- controlling the drive action of the drive section based on the reflected position and a target position on a side opposite the output section with respect to the image on the display surface;
- evaluating, based on the result of the detection of the reflected position, whether or not the reflected position coincides with the target position;
- and
- when the target position is not detected as the reflected position, determining, based on a relationship between an amount of the drive action of the drive section and an amount of movement of the reflected position, a target drive amount that allows the reflected position to move to the target position, and driving the drive section by the target drive amount.
An image display apparatus comprising:
- a display section that displays an image on a display surface;
- an output section that outputs light;
- a changer that changes an angle of the light outputted from the output section with respect to the display surface, wherein the changer includes a drive section and an adjustment mechanism that changes the angle in accordance with a drive action of the drive section;
- a position detector that detects a reflected position where the light outputted by the output section is reflected directly on the display surface;
- and
- a change controller that controls the changer based on a result of the detection performed by the position detector, wherein the change controller controls the drive action of the drive section based on the reflected position detected by the position detector and a target position on a side opposite the output section with respect to the image on the display surface, wherein
- the adjustment mechanism includes a first adjustment mechanism that rotates the output section around a first axis of rotation and a second adjustment mechanism that rotates the output section around a second axis of rotation that intersects the first axis of rotation.
