在一种实施例中,所述第三位置不同于所述第二位置和所述第一位置。
以下结合附图来介绍本发明实施例提供的投影方法。
如图1a中所示,当投影机被直立摆设,投影光路经过位于第一位置的反射镜片反射到桌面,实现短焦投影。
如图1b中所示,当投影机被横躺摆设,反射镜片位于第二位置,不对投影光路进行反射,投影光路直接投射到墙面,实现长焦投影。
第一位置不同于第二位置。
在图1a和图1b中,投影光路从投影机出来的地方,可以设置有透镜。
反射镜片可以是球面反射镜。用于控制反射镜片位置的机械结构可以采用现有的一些结构,如齿轮结构,杠杠结构等,投影机可以通过处理器
给该机械结构控制信号,来控制该机械结构来调整该反射镜片的位置。
图1b中,反射镜片所处的第二位置仅为一种示例,只要在该位置反射镜片不对投影光路进行反射即可。
可以在投影机内设置一个机械结构,此机械结构可以利用电力将一个小型的镜片或者是一个反射镜片推入到投影机投影光路的中心,可将投影机的投射光学特性改变(如方向/焦距/大小)。
投影机内部可以设置有能识别角度的传感器,通过能识别角度的传感器检测目前投影机的摆放姿态,一旦检测到投影机换了摆放姿态,就可以决定当下光路怎么投射,进而自动改变投影光路(包括改变反射镜的位置)以实现自动调整投影模式。在用户一开机时,通过能识别角度的传感器感知目前投影机的摆放姿态,确定当前摆放姿态下对应的投影模式,进而确定反射镜应该处于的位置,若反射镜已经处于该位置,则不用调整该反射镜的位置,若反射镜并未处于该位置,则可以通过控制一些机械结构来调整该反射镜的位置,将该反射镜推动到该位置,进而实现该投影模式下对应的投影光路。
通过自动检测投影机的摆放形态,在用户一开机或一改变投影机的摆放形态,投影机就可以立马自动调整投影模式,不需要用户繁琐的操作或设定。
