摘要 |
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. |

1. An information input device comprising:
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 by increasing intensity of an outermost photo-detection signal 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, wherein the input panel is an input/output panel including the plurality of photodetectors and a plurality of display elements in an effective display region which is defined as the same region as the effective photo-detectable region, and the correction section performs in-plane correction to the photo-detection signals from the photodetectors with use of an in-plane correction table in which a correspondence between an in-plane correction factor and a position within the effective photo-detectable region is defined, the in-plane correction factor having in-plane distribution in accordance with both of in-plane intensity distribution of light emitted from the effective display region and in-plane photo-sensitivity distribution of the plurality of photodetectors; and wherein the in-plane distribution of the in-plane correction factor corresponds to an inversion of composite distribution of the in-plane intensity distribution of light and the in-plane photo-sensitivity distribution, and the correction section performs the in-plane correction through multiplying a photo-detection signal from each of the photodetectors by the corresponding in-plane correction factor. |
