摘要： An image generating unit of a display apparatus generates a determination image based on first and second light reception images obtained from light reception cells in a light-emission period and in a non-light-emission period, respectively. An image determining unit determines whether or not an image of an object to be detected is included in the determination image, stores data corresponding to the determination image as initial data into a storage when the object image is not included in the determination image, and stores the data corresponding to the determination image as detection data into the storage when the object image is included in the determination image. A position determining unit determines at least an object position based on an image represented by the detection data in the storage and an image represented by the initial data in the storage.

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.

摘要： An HPF eliminates an image of an object which is not to be detected from a captured image, thereby obtaining an HPF image. A binarizing unit performs a binarizing process on the HPF image, thereby generating a binary image. A peak detector extracts, using the binary image as a mask, an image of a region corresponding to an opening of the mask from the captured image. From the image, a peak value and the position of a peak pixel are detected. A determining unit determines whether an object to be detected is in contact with the display surface or not on the basis of the relation between the difference and the threshold. Using the detection result and the determination result in the determining unit, a position deriving unit derives the position on the display surface, of the object to be detected which is in contact with the display surface.

摘要： An image pickup device capable of stably detecting an object irrespective of use conditions while reducing manufacturing costs is provided. When illumination light from a backlight 15 is emitted to a proximity object from an I/O display panel 20, an electric charge for charging is accumulated in each of image pickup pixels 33 in accordance with total light amount as a summation of reflected light Lon originating from the illumination light and environment light (outside light) L0. Moreover, when the above-described illumination light is not emitted, an electric charge for discharging is released from each of the image pickup pixels 33 in accordance with light amount of the environment light L0. Thereby, a component by the environment light L0 is subtracted in an image pickup signal obtained from each of the image pickup pixels 33, so object information about the proximity object is obtainable without influence of the environment light L0. Moreover, in a light reception drive circuit 13, a smaller number of necessary frame memories 13A for producing a picked-up image from the image pickup signal than that in related art are necessary.
