Abstract
An image input detection apparatus comprises: a voltage applier that applies a voltage of a predetermined waveform to a display medium; a first acquisition unit that acquires a vibration waveform generated in the display medium; a first memory that stores a vibration waveform determined based on the waveform of the voltage applied by the voltage applier; and a second memory that stores information representing that an image written on the display medium has been overwritten, when the difference between the waveform acquired by the first acquisition unit and the waveform stored in the first memory lies within a threshold value.
