The present invention provides an image input/output device including an input/output panel, a correction section and an image processing section. The input/output panel includes display elements and photo-reception elements to receive lights emitted from the display plane and then reflected from an external adjacent object. The correction section corrects photo-reception signals from the photo-reception elements based on an in-plane correction table where correction coefficients are associated with positions on the display plane, respectively. A value distribution profile in the display plane of the correction coefficients is defined based on both of a light intensity distribution profile of the light emitted from the display plane and a photo-reception sensitivity distribution profile of the photo-reception elements. The image processing section obtains information concerning one or more of position, shape and size of the external adjacent object based on the photo-reception signals corrected by the correction section.
