PROBLEM TO BE SOLVED: To efficiently transfer information from an information display apparatus to an imaging apparatus while safely performing setting of the imaging apparatus.SOLUTION: A setting terminal 110 displays, on a screen 110a, composite video obtained by composing clock video whose concentration difference of a first color component changes according to a waveform of a clock signal and data video whose concentration difference of a second color component changes according to a waveform of a data signal. A camera 130 acquires video by imaging the screen 110a; separates video of the first color component and video of the second color component from the acquired video; identifies the waveform of the clock signal from change in concentration difference in the separated video of the first color component; identifies the waveform of the data signal from change in concentration difference in the separated video of the second color component; and acquires data by using the identified waveform of the data signal and identified waveform of the clock signal. |
