Abstract
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.
