Abstract
Provided is an image pickup device with which object detection can be performed with a good stability no matter in what use conditions. A display areaof an I/O display panelis provided therein with a plurality of main sensorseach including, as a photosensitive wavelength region, a wavelength region Δλof detection light for use to detect any proximity object, and a plurality of auxiliary sensorswhose photosensitivity in the wavelength region of the detection light is lower than photosensitivity of the main sensors. Moreover, with use of a composite image F derived based on a differential image MC obtained by the main sensorsand a differential image HC obtained by the auxiliary sensors, object information about the proximity object is acquired. Accordingly, even when the proximity object is moving on the display areaof the I/O display panel, for example, any false signal can be prevented from being generated in the composite image F.
