Abstract
An information input device includes: an input panel having an effective photo-detectable region in which a plurality of photodetectors are arranged for detecting an external proximity object, and having a shading region located in a margin of the effective photo-detectable region; a correction section performing outermost-region correction on an outermost photo-detection signal to increase intensity thereof, the outermost photo-detection signal being obtained from a photodetector located in an outermost-region of the effective photo-detectable region; and an image processor acquiring object information about one or more of a position, a shape and size of the external proximity object based on a resultant photo-detection signal obtained from the outermost-region correction.
