摘要： An image display apparatus improves usability for a user in the case where a screen image is projected on a ceiling as a screen. The image display apparatus includes: a projection unit capable of vertically changing a projection angle; a projection angle detector detecting the projection angle of the projection unit; and a screen image corrector reversing a projected screen image. The screen image corrector switches the projected screen image from a reversed display to a standard display when the projection angle detected by the projection angle detector is less than or equal to a predetermined value.

摘要： An image display apparatus detects a projection angle of a projection unit that projects a screen image on a screen and is capable of vertically changing the projection angle, and corrects trapezoidal distortion of the screen image according to the projection angle. The image display apparatus changes the amount and direction of trapezoidal distortion correction based on the projection angle. The image display apparatus also determines whether a projection mode is projection upward to a wall or projection to a ceiling and changes the direction of trapezoidal distortion correction for projection upward to the wall and projection to the ceiling. Specifically, for projection upward to the wall, a correction factor is positive and an upper edge portion of the screen image is compressed for correction; and for projection to the ceiling, a correction factor is negative and a lower edge portion of the screen image is compressed for correction.
摘要翻译：图像显示装置检测在屏幕上投射屏幕图像的投影单元的投影角度，并且能够垂直地改变投影角度，并根据投影角度校正屏幕图像的梯形失真。图像显示装置基于投影角度改变梯形失真校正的量和方向。图像显示装置还确定投影模式是向上投射到墙壁还是投射到天花板，并且改变梯形失真校正的方向以向上投射到墙壁和向天花板的投影。具体来说，为了向墙壁上方突出，校正系数为正，屏幕图像的上边缘部分被压缩以进行校正; 并且为了投影到天花板，校正因子为负，并且屏幕图像的下边缘部分被压缩以进行校正。
