INPUT DISPLAY DEVICE, METHOD OF RECOGNIZING INPUT POSITION

摘要

Disclosed is an input display device which includes a plurality of arrayed optical sensors and recognizes an input position on a display unit of a light emitting device or a reflection device, wherein the input display device calculates from the detection results of each optical sensor the illuminance index value of each of a plurality of areas included in the display unit, defines an illuminance index value of one area as a focus value, defines as a corrected value for the one area the difference between the above focus value and the result of dividing the total sum of N comparison values obtained from the illuminance index values of N areas (N is an integer greater than or equal to two) in the proximity of the above one area by N, and recognizes the above input position by calculating the corrected value for each area.
