The region of interest is an area including at least one of a facial region and a belonging region, which is a line in the image of the line-in, and is an area where the characteristics of the line-in can be extracted more easily.

Then, the characteristic information extracting unit extracts the characteristic information from the extracted region of interest.

For example, the characteristic information extracting unit extracts characteristic information using at least one of Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA), and Gabor Wavelet (GW) for the ROI. PCA, LDA, or GW is a method of extracting feature information in a vector format by applying a feature dimension reduction algorithm.

The feature information extracting unit extracts the feature information by comparing the extracted feature information with previously stored reference information. Of course, the characteristic information extracting unit compares the extracted characteristic information with other characteristic information already stored to identify whether or not the extracted characteristic information is the same.

As described above, the characteristic information may include at least one of gender information, age information, facial expression information, and belonging information, for example, of a passport.

Accordingly, the previously stored reference information can be generated and stored based on at least one of sex, age, facial expression, and personal belongings, and can be stored in a vector format for comparison with the feature information.

For example, for recognition of gender, the reference information may include discrimination information according to man or woman.

In addition, for the recognition of age, the reference information may include previously learned identification information for each age group so as to easily extract the characteristics of the age.

Also, in order to recognize the facial expression, the reference information may include previously learned discrimination information so as to easily extract a feature of a facial expression according to various emotional states of a person.

The control module causes the information output module of the illumination to output customized information on the characteristic information extracted by the characteristic information extracting unit.
