Abstract:
A coordinate-position inputting/detecting device comprising:at least two image pickup elements provided with a prespecified space therebetween on a peripheral section of an entry area, the at least two image pickup elements each providing an output indicating a portion of each of the at least two image pickup elements receiving an illuminated image of a pointing body inserted into said entry area to perform an entry operation; coordinate-value identifying means for computing positions where each illuminated image is formed on each of said at least two image pickup elements according to each corresponding output from said at least two image pickup elements and for identifying coordinates of a position of said pointing body by using the computed positions; storing means for storing the coordinates first identified by said coordinate-value identifying means as first coordinates; determining means for determining whether the first coordinates stored in said storing means are coincident with updated coordinates newly identified by said coordinate-value identifying means or not; and updating means for replacing the first coordinates stored in said storing means with said updated coordinates and outputting the updated coordinates when it is determined by said determining means that the first coordinates and the updated coordinates are not coincident, while abandoning the updated coordinates when it is determined by said determining means that the first coordinates and the updated coordinates are coincident and are continuously identified as being coincident over a prespecified period of time.
