Video information processing apparatus and transmitter for transmitting information to the same
A video information processing apparatus includes an input device which inputs video, a memory device which stores identification information corresponding to the blinking pattern of a blinking light source, a blinking light decoder which converts the blinking pattern of the light source blinking in the video information input by the input device into corresponding identification information on the basis of the identification information stored in the memory device, and an output device which outputs together with the input video the identification information converted by the blinking light decoder.
1. A video information processing apparatus associated with a blinking light source, comprising:
an input device configured to input video information;
a memory device configured to store identification information corresponding to a blinking pattern of the blinking light source;
blinking light decoder for converting the blinking pattern of the blinking light source, blinking in the video information input by said input device, into corresponding identification information on the basis of the identification information stored in said memory device; and
a video processing device configured to selectively process the input video in accordance with the identification information converted by said blinking light decoder,
wherein said blinking light decoder includes means for dividing a video in a number of video elements arranged in a matrix pattern, means for calculating a motion vector at each of the video elements and means for determining as a region to be processed a portion having a motion vector different from a background.
2. A video information processing apparatus associated with a blinking light source, comprising:
an input device configured to input video information;
a memory device configured to store identification information corresponding to a blinking pattern of the blinking light source;
blinking light decoder for converting the blinking pattern of the blinking light source, blinking in the video information input by said input device, into corresponding identification information on the basis of the identification information stored in said memory device; and
a video processing device configured to selectively process the input video in accordance with the identification information converted by said blinking light decoder,
wherein said blinking light decoder includes a detector configured to detect as a region to be processed a portion where a hue histogram greatly changes in a video region expanded from a portion of the blinking light source.
