Document Type and Number:
Japanese Patent JP2018182589
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an information provision system capable of synthesizing information with video content to display the information without giving influence on designability.SOLUTION: A code determination part determines a code of a binary image synthesized on a screen of video content in each pixel, and a frequency component synthesis part adds a desired frequency component in a time axis direction to pixel data of the video content in accordance with the code of the binary image in each pixel, and displays the desired frequency component synthesized with the pixel data in a display part. An imaging part images an image displayed in the display part, a pixel data acquisition part acquires pixel data from the image picked up by the imaging part, a frequency component analysis part analyzes whether the desired frequency component is included in the pixel data acquired from the pixel data acquisition part in each pixel, and a decoding part decodes the code of the binary image from an analysis result of the frequency component analysis part.SELECTED DRAWING: Figure 20
