Title:
INFORMATION RECEPTION DEVICE, INFORMATION TRANSMISSION SYSTEM, AND INFORMATION RECEPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2005/117304
Kind Code:
A1
Abstract:
By acquiring a region required for detection of a luminance modulation, it is possible to increase the speed of the information restoration process. Moreover, it is possible to facilitate the position adjustment of the luminance modulation region. An information reception device (22) includes: imaging means (34, 57); light reception means (35, 61) for photo-receiving arbitrary information subjected to luminance modulation; specification means (31, 53) for specifying a luminance modulation region contained in the imaging angle of view of the imaging means; restoration means (50, 53) for controlling the light reception means so as to photo-receive the luminance modulation region specified by the specification means and restoring arbitrary information from the luminance modulation content contained in the region; and reproduction means (47) for reproducing arbitrary information restored by the restoration means.
