  • Patent number: 8300005
    Abstract: The present invention is to reduce power consumption in a display that concurrently (or alternately) implements light emission and light reception in parallel. A display is provided with a display panel configuration including a plurality of display elements arranged in a matrix and a plurality of light-receiving elements that are disposed adjacent to the plurality of display elements and receive light incident on a display plane. In addition, the display includes a position detector that determines the position of contact or proximity to the display plane based on a light reception signal arising from light reception by the light-receiving elements. Furthermore, the display includes a controller that shifts the displaying state or the position detection state from the low power consumption mode to the normal operation mode if the position detector has determined the presence of contact or proximity in a predetermined state.

  • Publication number: 20120194480
    Abstract: 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.

  • Patent number: 7965266
    Abstract: An image display unit and a method of detecting an object which are capable of reliably detecting an object with a simple structure irrespective of use conditions are provided. Invisible light is emitted from a screen of a display portion. The invisible light reflected from a target object which comes in contact with or close to the screen is received on the screen. On the basis of the received invisible light, the target object is detected. Thus, the target object can be reliably detected without influence of the display state of the display portion, and influence of use conditions such as surrounding circumstances (the case where it is bright or dark). Moreover, for example, it is not necessary to separately arrange a component such as a touch panel, so the image display unit can be achieved with a simple structure.

  • Publication number: 20100253642
    Abstract: 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.

  • Publication number: 20100128004
    Abstract: 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.

  • Publication number: 20100045811
    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.
