Abstract
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.
