Patent number: 11657244Abstract: A system contributing to prevention of unauthorized use of an information code displayed on a screen. In the system, an information code display device cyclically displays a plurality of partial code images on a display screen of a display unit based on a first rule when the first rule is received from a server in response to a first request to the server. Accordingly, an information code reading device captures images of the display screen at imaging intervals according to a second rule which is received from the server by in response to a second request to the server to decode an information code composed of the plurality of images thus captured, according to the second rule.Type: GrantFiled: September 1, 2020Date of Patent: May 23, 2023Assignee: DENSO WAVE INCORPORATEDInventors: Tomohito Suzuki, Yuichi Ito, Ryohei Kagami, Koji Konosu

Patent number: 9129198Abstract: Disclosed herein are an information code and an information code reader. In information code, a plurality of light-colored modules exhibiting the reflective characteristics of light color when light of a second wavelength band different from light of a first wavelength band is radiated and a plurality of dark-colored modules exhibiting the reflective characteristics of dark color when the light of a second wavelength band is radiated are arranged in a code region. The information code includes a masked portion disposed in a predetermined region of the code region in which light is intercepted and prevents the corresponding information code from being read, and configured to, when the light of a second wavelength band is radiated, allow light reflected from the modules of the corresponding code region to pass therethrough and thereby interrupt the light of a first wavelength band.Type: GrantFiled: March 15, 2012Date of Patent: September 8, 2015Assignee: DENSO WAVE INCORPORATEDInventors: Manabu Miyazaki, Takao Ushijima, Koji Konosu, Atsushi Tano

Patent number: 9082032Abstract: A system reads an information code formed on a medium. The code has light modules and dark modules. The areas of the light modules are produced as inversion areas inverted light reflection characteristics. The areas of the dark module areas are produced as non-inversion areas non-inverting light reflection characteristics. A reader emits illumination light of wavelengths including infrared light wavelengths to the code, and images the code under the illumining light emission. The inversion areas, that is, the light module areas, can be dark under the visible light, but can be a light color due to its inverted light reflection characteristics. The light modules can thus be imaged by the reader under the illumining light emission, providing distinguishable detection of the inversion and non-inversion areas, allowing the light and dark modules to be extracted for decoding.Type: GrantFiled: February 23, 2012Date of Patent: July 14, 2015Assignee: DENSO WAVE INCORPORATEDInventors: Yuichi Ito, Koji Konosu, Takao Ushijima, Jun Ogawa

Patent number: 7871003Abstract: An information reader has blocks of bright field illuminating units illuminating an information code directly marked on an object with first lights to regularly reflect the lights on the code, blocks of dark field illuminating units illuminating the code with second lights to irregularly reflect the lights on the code, an optical system, and a control section lighting the blocks of bright and dark field illuminating units by turns or simultaneously. The optical system forms an image of the code from each of the first and second lights or a combination of the first and second lights reflected on the code and reads the code from the images. The first lights are transmitted along an optical axis of the optical system. The second lights are transmitted toward the optical axis while slightly shifted toward the code.Type: GrantFiled: July 17, 2007Date of Patent: January 18, 2011Assignee: Denso Wave IncorporatedInventors: Manabu Miyazaki, Kunihiko Ito, Koji Konosu
