摘要： 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 area 21 of an I/O display panel 20 is provided therein with a plurality of main sensors 32 each including, as a photosensitive wavelength region, a wavelength region Δλ23 of detection light for use to detect any proximity object, and a plurality of auxiliary sensors 33 whose photosensitivity in the wavelength region of the detection light is lower than photosensitivity of the main sensors 32. Moreover, with use of a composite image F derived based on a differential image MC obtained by the main sensors 32 and a differential image HC obtained by the auxiliary sensors 33, object information about the proximity object is acquired. Accordingly, even when the proximity object is moving on the display area 21 of the I/O display panel 20, for example, any false signal can be prevented from being generated in the composite image F.

摘要： An image pickup apparatus capable of easily improving the detection accuracy of a touching or proximity object is provided. An offset noise (a reset image R) is obtained by an image pickup process in a state (a reset state) in which an image pickup device is initialized. Moreover, a fingertip extraction process is performed in consideration of the offset noise on the basis of a picked-up image (a shadow image A or a display light-using image B) which is obtained by picking up an image of a proximity object to obtain object information about the proximity object. While an offset noise in the apparatus is easily reduced, object information about the proximity object can be obtained.
