  • Patent number: 7612744
    Abstract: In order to carry out information transmission/reception intuitively and easily, a black-and-white pattern of a symbol representative of data of an image is switched every scan timing of one frame of a display unit and is displayed continuously only during a period displaying whole data of the image. In an information processing terminal, the data of the image is acquired in accordance with the symbol read by a reader/writer. To the contrary, in a case of transmitting data from the information processing terminal to a display apparatus, a symbol representative of data to be transmitted is output from the reader/writer to be read by a read area formed at a predetermined position of the display unit. In the display apparatus, data is acquired in accordance with the read symbol. The present invention may be applied to various information processing apparatuses including a personal computer, PDA, a television receiver.

  • Publication number: 20090225058
    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.

  • Publication number: 20090213095
    Abstract: A displaying and imaging apparatus includes a displaying and imaging panel, a generating unit for generating a difference image between a reflection light using image and a shadow image obtained from the displaying and imaging panel, and an image processing unit for obtaining information of at least one of position, shape, and size of the adjacent object on the basis of the difference image. The generating unit generates, on the basis of a plurality of images obtained at timings different from each other, which are one of the reflection light using image or the shadow image, one interpolation image corresponding to the one of images obtained at a timing different from those of the plurality of images, and generates the difference image by the difference between the interpolation image and the other one of the reflection light using image and the shadow image.

  • Publication number: 20090207145
    Abstract: 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.

  • Publication number: 20090033638
    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.
