| Zusammenfassung: | The present invention provides a position detecting device which is operable even when a distance from an image sensor to a corner portion of a coordinate inputting device is shortened, and which enables cost reduction, and an image processing system having the same. In the present invention, a position detecting device is placed on an upper surface portion of a frame body of a coordinate inputting device, and each of at least two image sensors has a wide-angle lens which covers a substantially entire region of side surface and bottom surface portions of the frame body as an image pickup range. The at least two image sensors are arranged adjacent to a control device and fixed to the control device. The position detecting device is placed substantially in a center of the upper surface portion of the coordinate inputting device. |
