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.

摘要： An image processing apparatus which is allowed to achieve a higher speed of a labeling process than ever before is provided. Sequential scanning is performed on pixels in a picked-up image represented by binarized data Din. Moreover, during the sequential scanning, while label information representing an identification number for each connected region in the picked-up image is, as occasion arises, allocated to a target pixel based on values of pixel data of the target pixel and neighboring pixels thereof, additional information (position information and area information) for each connected region corresponding to each label information is updated as occasion arises. Thereby the label information, the position information and the area information about the whole picked-up image are obtained by one sequential scanning process.

摘要： The imaging and display apparatus is provided. The imaging and display apparatus includes the following elements. An imaging-and-display panel has an image display function and an imaging function. A generation unit generates a difference image representing a difference between a display-light-based image and a shadow image, the display-light-based image being obtained by the imaging-and-display panel by imaging an object close to the imaging-and-display panel using display light from the imaging-and-display panel, the shadow image being obtained by the imaging-and-display panel by imaging a shadow of the object. An image processing unit obtains information concerning at least one of a position, shape, and size of the object taking the shadow image and the difference image into account.
