综上所述,本发明实施例的投影装置,其第一相机模块的第二光轴以及第二相机模块的第三光轴分别倾斜于影像投影模块的第一光轴,进而增加投影区域、第一拍摄区域以及第二拍摄区域彼此至少部分重迭的重迭区域,藉以增加感测操控的性能。
以上所述,仅是本发明的较佳实施例而已,并非对本发明作任何形式上的限制,虽然本发明已以较佳实施例揭露如上,然而并非用以限定本发明,任何熟悉本专业的技术人员,在不脱离本发明技术方案范围内,当可利用上述揭示的方法及技术内容作出些许的更动或修饰为等同变化的等效实施例,但凡是未脱离本发明技术方案的内容,依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰,均仍属于本发明技术方案的范围内。
