Abstract

An information acquisition method includes: acquiring, for each of frames, a brightness value corresponding to a position of a color filter from a light receiving device including light receiving elements whose light receiving surfaces are covered with color filters, the color filters including the color filter and the color filters comprising at least first color filters transmitting light of a wavelength band corresponding to a first color and second color filters transmitting light of a wavelength band corresponding to a second color (S101); and acquiring information on a mobile device based on difference between brightness values of the position acquired from a plurality of frames and at least one of a threshold for the first color filters and a threshold for the second color filters (S106).

Description

technical field [0001] The invention relates to an information acquisition method and an information acquisition device. Background technique [0002] In the past, in the visible light communication technology, a visible light communication system has been proposed, the visible light communication system includes: a sending device, the sending device is a signal source, and the signal source converts red (R), green (G), blue (B ) The combination of these three primary colors (RGB) is replaced by the information that should be transmitted, so that these colors emit light as time changes; the camera shoots the space including the sending device one by one, and according to the change of the luminous color of the sending device over time (time change in direction) to decode the information. [0003] In this visible light communication system, in order to determine which of the three primary colors the emission color of the transmitting device is on a frame-by-frame basis, a pr...
