Title:
DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2014/103333
Kind Code:
A1
Abstract:
A display method, with which the probability of communication errors can be reduced without causing a significant deterioration in image quality, includes: a light-emission-time-period specification step (SL21) in which a light-emission time period, in which light is emitted for at least a time required to transmit a block configuring a visible-light-communication signal, is specified as a specific light-emission time period, from among at least one light-emission time period in which light is emitted in order to display an image included in a video signal; and a transmission step (SL22) in which the block configuring the visible-light-communication signal is transmitted by changing brightness during the specific light-emission time period.
