    • The present invention relates to a camera module which senses the position of an on object touching a touch surface of an optical touch screen. The camera module comprises one or more lenses, an optical path converting unit, and an image sensor. Each of the lenses is arranged such that the angle of view for the direction vertical to the touch surface is smaller than the angle of view in the direction horizontal to the touch surface. The optical path converting unit reflects light converging through the lenses in the direction vertical to the touch screen. The image sensor is arranged behind the lenses and in the direction horizontal to the touch surface so as to receive the light reflected by the optical path converting unit.
    • 本发明涉及一种摄像机模块,其检测接触光触摸屏的触摸表面的物体的位置。 相机模块包括一个或多个透镜,光路转换单元和图像传感器。 每个透镜被布置成使得垂直于触摸表面的方向的视角小于在与触摸表面水平的方向上的视角。 光路转换单元沿垂直于触摸屏的方向反射会聚在透镜上的光。 图像传感器布置在透镜后面并且在与触摸表面水平的方向上,以便接收由光路转换单元反射的光。
