摘要： There is provided a safe image display apparatus for projecting an image on a screen that can minimize a stimulus to eyes, retinae and optic nerves from projected light entering into the eyes directly. By comparing a displayed image captured by a camera with an input image signal, a changed area is detected as a difference area and, then, a projected image signal is generated wherein a picture area image signal in the input image signal that corresponds to this difference area is masked by a black signal. The obtained projected image signal is projected onto the screen.

摘要： In measuring the angle of inclination of a liquid crystal projector with respect to the screen for automatically adjusting a trapezoidal distortion, the calculation of the angle of inclination by determining the distance from the screen using a distance sensor conventionally requires a high distance measurement accuracy and hence an expensive distance sensor. According to the invention, a distance sensor is rotated and the level of the wave reflected from it is observed. The angle of inclination with respect to the screen is detected from the rotational angle associated with the maximum value of the level of the reflected wave thereby to correct the trapezoidal distortion. In this way, the trapezoidal distortion can be adjusted automatically using an inexpensive distance sensor.
