摘要:
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.

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.
摘要:
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.

The reflecting mirror for leading the image forming light bundle emitted from an image pickup optical system to an image forming surface has an area for reflecting the effective image forming light bundle, and another marginal area which is located outside said area, and has a reflecting characteristic different from that of said area and varying gradually outward. Accordingly, the reflecting mirror is capable of blurring the boundary of the veiling glare and reducing appearance of detrimental images. The variation of the reflecting characteristic on said outside marginal area can be realized by varying reflectance or light diffusing characteristic of the outside marginal area.

A method for more easily marking an optical recognition code is accomplished.First, a red ribbon-shaped thread, a green ribbon-shaped thread and a blue ribbon-shaped thread are woven into a fabric mark object in three lines. Next, black embroidery patches are provided in predetermined regions of the ribbon-shaped threads by embroidering to partially cover and thus mask the ribbon-shaped threads. Through the above two steps, a color bit code is marked on the fabric mark object by exposing the colors of the portions wherein the black embroidery patches are not provided.

A method that lays a certain restriction on a distance between color areas and carries out “cutting out” and “sequence recognition.”In an optical recognition code which aligns a plurality of cells to predetermined color is affixed and denotes a data by a sequence of colors, distance between the cells is stipulated to allow an easier reading-out of the code. A distance between the cells contiguous to each other is > a predetermined minimum value and

A method for displaying the result in an improved manner in the case of collectively reading in and recognizing a plurality of 1D color bit codes is provided. A “recognized data” as a result of recognizing a code symbol and a “corresponding pattern specific display” indicating the successfully recognized code symbol are displayed in such a manner as superimposed on the original image. The recognized data is a data successfully recognized from the code symbol. The corresponding pattern specific display is a graphic pattern for indicating a finally successfully recognized code symbol, such as a rectangular frame (utilizing a conspicuous color, e.g., orange and the like), etc. By virtue of such a display, the operator is able to know which code symbol was recognized and what the recognition result is, and thereby a highly convenient optical recognition code recognizer and method can be obtained.
