  • 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: 20090146968
    Abstract: An image acquisition section 105 obtains an image of a finger by bringing the finger into touch with a display 13 formed of a device including an image pickup device and picture elements or by bringing the finger closer to the display without touching the display. A computing section 120 determines a center-of-gravity position of the finger, based on the obtained image of the finger. An information generating section 125 generates information for operating the cellular phone based on a displacement of the center-of-gravity position of the finger r. A determination section 115 determines whether the finger has touched the screen or not, based on the touch area between the finger and the screen. A display section 130 displays a virtual sign 14 indicating a reference point for subsequent movement of the finger, at a first position that the finger has touched the screen.

  • Publication number: 20090123029
    Abstract: A display-and-image-pickup apparatus includes: a display-and-image-pickup panel having an image display function and an image pickup function; an image producing means for producing a predetermined processed image on the basis of a picked-up image of a proximity object obtained through the use of the display-and-image-pickup panel; an image processing means for obtaining information about the proximity object through selectively using one of two obtaining modes on the basis of at least one of the picked-up image and the processed image; and a switching means for switching processes so that, in the case where the parameter is increasing, one of the two obtaining modes is switched to the other obtaining mode when the parameter reaches a threshold value, and in the case where the parameter is decreasing, the other obtaining mode is switched to the one obtaining mode when the parameter reaches a smaller threshold value.

  • Publication number: 20080231564
    Abstract: Disclosed herein is a display apparatus including: a display panel having a display function and a light-receiving/imaging function; a first image processing section configured to generate a detection signal that indicates whether a to-be-detected object has been detected based on a result of first image processing performed on an image taken by the light-receiving/imaging function; a second image processing section configured to perform second image processing on the image processed by the first image processing section, the second image processing having a heavier processing load than the first image processing; and a control section configured to control an operation of the second image processing section in accordance with the detection signal generated by the first image processing section, and, when it is determined that the processing by the second image processing section is not necessary, control the second image processing section to enter a sleep state.

  • Publication number: 20080136754
    Abstract: Disclosed herein is a display apparatus including an input/output section for displaying an image as well as detecting a light beam representing an input received from an external source and is capable of handling inputs received from the external source as inputs destined for a plurality of points on a display screen. The apparatus further includes a target generation section configured to generate information on a target located on the display screen to represent a series of inputs received from the external source on the basis of a timewise or spatial relation between input portions located on the display screen as portions receiving inputs from the external source. The apparatus still further includes an event generation section configured to recognize an event representing a change of a state of the target on the basis of the information on the target and generate information on the event.

  • Publication number: 20080055266
    Abstract: 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.
