  • Patent number: 10602142
    Abstract: An image decoding apparatus that includes a motion compensation prediction circuit configured to conduct motion compensation prediction for each of blocks to be decoded by using the reconstructed image, an inverse transformation circuit configured to conduct inverse orthogonal transformation for the data of the blocks to be decoded, and a determination circuit configured to determine a filtering strength and whether or not to conduct filtering, with respect to each of the boundaries. In addition, the determining circuit is configured to determine filtering is conducted when at least one of the two adjacent blocks is intra-coded, and filtering is not conducted when both of the two adjacent blocks are not intra-coded, a non-zero transformation coefficient is not coded in both of the two adjacent blocks, the two adjacent blocks are predicted by the same reference frame, and an absolute value of a difference between motion vectors of the two adjacent blocks is smaller than a specified threshold value.

  • Publication number: 20190271843
    Abstract: A display unit is configured to display visual information that is visually recognized and superimposed on an external scene. A detection unit is configured to detect an event possibly causing danger by visually recognizing the visual information. A mounting unit is configured to be mountable on a head of a user and support the display unit and the detection unit. A controller is configured to suppress display of the visual information on the display unit in a case that the event is detected. Embodiments of the present invention can be applied to any of a terminal apparatus, a communication method, or a program.

  • Publication number: 20170223545
    Abstract: Provided are a communication terminal device with which a user can easily recognize restriction contents when access is restricted, and a control method therefor. A communication terminal device configured to control access restriction according to access restriction information received includes: a restriction determination unit configured to determine whether or not access restriction is valid; and a control unit configured to, in a case that it is determined that the access restriction is valid, emphasize only a display of a service permitted to be used under the access restriction. This enables the user to easily recognize restriction contents when access is restricted.
