Projection apparatus, projection method and projection program medium that determine a roll angle at which the projection apparatus is to be turned to correct a projected image to be a rectangular image on a projection target
Abstract:
A CPU controls an attitude adjustment unit to change the lengths of legs of an electric leg part independently of each other so that a roll angle is changed to roll a projected image, and controls an image converter to correct the projected image to be a rectangular image on a projection target based on the changed roll angle.
Abstract(Chinese):

CPU控制姿势调节单元，以独立于彼此独立的方式改变电脚部分的腿的长度，从而改变滚动角度以滚动投影图像，并且控制图像转换器将投影图像校正为矩形图像 基于改变的滚动角度在投影对象上。
