Abstract: A network node is provided that communicates with a first terminal, which supports a first codec and a second terminal. The network node includes a detector that detects switching of a codec of the first terminal and the second terminal, wherein the first codec supports a codec A compatible mode and a codec A non-compatible mode, the first codec being a new codec and codec A having a dedicated payload format, and wherein the codec A compatible mode is compatible with a second codec and the codec A non-compatible mode is non-compatible with the second codec, the second codec being a legacy codec. The network node also includes a transmitter that transmits a signal for the second terminal to switch the negotiated codec A non-compatible mode of the second terminal to the codec A compatible mode.

Abstract: To switch a coordinate mode by automatically recognizing a coordinate mode more usable for a user performing a natural operation, a coordinate determination apparatus (200) according to the present invention includes: an obtain and store unit (204) which obtains coordinate information from a coordinate input device (201) and stores the coordinate information onto a recording medium; a time correlation specifying unit (320) which specifies a correlation between times of input indicated by first and second coordinate information; a coordinate correlation specifying unit (324) which specifies input coordinates indicated by the second and third coordinate information; a coordinate mode selection unit (326) which selects the coordinate mode based on a coordinate correlation value and a time correlation value; and a coordinate transform unit (328) which transforms the input coordinates indicated by the second coordinate information into coordinates selected according to the coordinate mode.

Abstract: A camera that includes a capture unit, a calculation unit, an object information acquisition unit, and an evaluation unit. The capture unit generates an image by capturing an area in which an evaluation-use object is present. The calculation unit analyzes the image, and thereby detects the evaluation-use object in the image and calculates meaningful information from the evaluation-use object in the image. The object information acquisition unit acquires and stores object information that is meaningful to a user and derived from the evaluation-use object. The evaluation unit performs an evaluation that includes comparing the meaningful information and the object information, and thereby calculating a degree of matching between the meaningful information and the object information, the evaluation determining whether or not a desired result is obtained from the image.
