20110150285 | LIGHT EMITTING DEVICE AND METHOD FOR TRACKING OBJECT - A technique and a light emitting device that can smoothly read out data while tracking a position of the light emitting device (an object). The light emitting device expresses data with “a change in the change of a color (switching of changes)”. The light emitting device specifies an object and the position thereof with a first primary change and thereafter expresses data with, so to speak, a secondary change (switching of the primary change). The primary change means that G and B alternately turn on (indicated by G*B) and so on. The secondary change means a change from the condition (G*B), in which G and B alternately turn on, to the condition (B*R) in which B and R alternately turn on. Thus, since data is expressed by the change of color condition changes, it is easier to freely express data while the position of an object is specified. | 06-23-2011 |
20100301120 | Method for denoting optical recognition data with multicolor light emitters, method for marking the same, light-emitting device, and method for detecting data and position - A technology to measure the position of a distant mark object and denote an automatic recognition data by the object. A light-emitting device includes an R (red) light, a G (green) light, and a B (blue) light emitters, and a control device for controlling their light-up states. The light-emitting device is affixed to the mark object and made to emit the lights by a predetermined light-emitting pattern. The light-emitting pattern forms a time-change optical recognition code denoting a desired data by change of the colors along the time axis. This optical recognition code is accomplished with a small area of space. Further, by photographing the light-emitting device with a CCD camera and the like, it is possible to recognize the position of the light-emitting device, that is, the position of the mark object. By carrying out this behavior continuously, it is possible to trace the movement of the mark object. | 12-02-2010 |
20100252636 | Optical recognition code, method for marking the same, method for reading out the same, and articles marked with the same - A method that lays a certain restriction on a distance between color areas and carries out “cutting out” and “sequence recognition.” | 10-07-2010 |
20090314838 | Optical Symbol, Article to which the Optical Symbol is Attached, Method for Attaching Optical Symbol to Article, Optical Symbol Decoding Method, Related Device, and Related Program - It is possible to linearly arrange cells and indicate particular data in the order of colors of respective sells. A code system uses an optical symbol decoding method capable of reading the color arrangement if the arrangement continuity and the linear shape are maintained. The data expression method may be other than “the order of colors.” For example, it is possible to employ a method for allocating a numeric value to each of the colors by one-to-one correspondence (R=0, B=1, etc.), a method for allocating data by a color transition (“CM”=“MY”=“YC”=0, “CY”=“YM”=“MC”=1, etc.), a method for allocating data for a combination of colors, and the like. | 12-24-2009 |
20090194596 | Optical Symbol, Item to Which Optical Symbol is Attached, Method of Attaching Optical Symbol to Item, and Optical Recognition Code Recognizing Method - It is possible to provide a code using an optical symbol which can be read with a high accuracy even under an environment of a low printing accuracy including printing on an article which can be easily deformed. Cells are arranged in a linear shape and particular data is indicated by a state of element in each of the cells (whether the element is colored). Especially a particular color is fixed to each of the elements and it is possible to use the two states whether the color is attached or note. This state can express the data. Accordingly, it is possible to realize a code system capable of ready data if the element sequence continuity and the form (topology) as the linear state are maintained. | 08-06-2009 |
