  • Patent number: 8385569
    Abstract: An acoustic transducer unit includes a first member having a recess, and a plate-like second member having main surfaces. The second member is bonded to the first member so as to cover the recess and form a housing. A microphone element, which is an acoustic transducer, is accommodated in an internal space of the housing, and an acoustic path is provided between the internal space and an external space of the housing. A conductive electromagnetic-shielding member and terminal members for electrically connecting the microphone element and an external circuit are embedded in a resin body of the first member by insert molding. An electromagnetic shield layer of the second member is electrically connected to the electromagnetic-shielding member.

  • Publication number: 20110134316
    Abstract: The image signal of each pixel of a frame image is multiplied by a gain value set in advance for each coordinate position on a display screen, generating a display frame image in which the luminance value becomes smaller for a pixel closer to the periphery of the display screen and larger for a pixel closer to the center. The image signal of each pixel of a subframe image is multiplied by a gain value set in advance for each coordinate position on the display screen, generating a display subframe image in which the luminance value becomes larger for a pixel closer to the periphery of the display screen and smaller for a pixel closer to the center of the display screen. The display frame image and display subframe image are sequentially displayed.

  • Publication number: 20090174697
    Abstract: An image display apparatus capable of displaying a preferable image whose dark place contrast has a large value and whose color-reproducibility and gray-level reproducibility are excellent. A voltage level of a scanning selective signal is changed in response to a request from outside or the like, so that a black level luminance is reduced to improve dark place contrast. In addition, when the voltage level of the scanning selective signal is changed, a conversion table for converting an input luminance into a modulation signal is changed to another conversion table. Therefore, for example, it is possible to maintain a display gray-level characteristic before and after the voltage level of the scanning selective signal is changed.
