    • A projector in which an image signal is inputted to project an optical image corresponding to the image signal and display the image on a projection surface, the projector including: an optical modulation unit having an area capable of modulation where light can be modulated for modulating the light emitted from a light source in the area capable of modulation to form an optical image; a projection lens for enlarging and projecting the optical image formed in the optical modulation unit; a forming area changing unit capable of changing a size or a shape of a forming area for forming an optical image corresponding to the image signal in the area capable of optical modulation; an operation part capable of inputting location information indicating a projection location of the optical image corresponding to the image signal; and a forming area moving unit for moving the forming area on the basis of the location information inputted by means of the operation part when the forming area changed in size or shape by means of the forming area changing unit is movable in the area capable of optical modulation.
    • 一种投影仪,其中输入图像信号以投影对应于图像信号的光学图像并在投影表面上显示图像,该投影仪包括:光学调制单元,具有能够调制光的区域,用于调制 从能够调制的区域的光源发出的光形成光学图像; 用于放大和投影形成在光调制单元中的光学图像的投影透镜; 形成区域改变单元,其能够改变用于形成与能够进行光学调制的区域中的图像信号对应的光学图像的形成区域的尺寸或形状; 能够输入表示对应于图像信号的光学图像的投影位置的位置信息的操作部; 以及形成区域移动单元,用于当成形区域通过成形区域改变单元改变尺寸或形状时,基于通过操作部分输入的位置信息来移动成形区域,该移动单元可在能够光学的区域中移动 调制。
