In the pore analysis, a region to be analyzed is selected from a front image taken with a flash in a polygonal shape, a circular shape, an elliptical shape, or the like, and the pore analysis is performed in the selected region. Specifically, the number of pores and the total area are digitized and the extracted region is colored.

  Here, a specific example of pore analysis will be described with reference to the drawings. FIG. 4 is a diagram illustrating an example of a pore analysis procedure. First, when selection of a region to be subjected to pore analysis is received from the input image (S01), a G component image is extracted from the RGB components of the selected image region (S02). Note that the RGB components are extracted using RGB data possessed by each pixel of the image.

  Next, the G image obtained in S02 is smoothed (S03). Here, for example, when the entire face is contained in 1944 × 1944 with an 8-bit image size, the smoothing filter size is preferably 2 to 16 pixels in the vertical and horizontal directions.

  Next, pore enhancement is performed from the difference between the G image obtained by the process of S02 and the smoothed image obtained by the process of S03 (S04). Specifically, the difference is performed by “smoothed image−G image × a (a is preferably 0.5 to 1.5)”. As a result, the pores are small and shaded, or small red portions can be extracted to make the analysis object stand out.

Further, the pores are extracted by binarizing the difference image (the binarization line is preferably 30 to 70) (S05), and the image is enlarged to extract a portion having a predetermined area to remove noise. (S06), and a pore image is extracted (S07). Specifically, it enlarges about 1 to 3 pixels, and extracts a portion having an area of 4 to 30 pixels as a pore. Further, the number of pores and the total area are calculated (S08), and the extraction region is colored with a color different from the skin color such as red or green in the original image (S09). Incidentally, 4-30 pixels extracted as pores in the above embodiment, the actual on the skin corresponds to the area of of 0.02 to 0.5 mm ^2.

  Note that, in the above-described processing of S02, the same pore analysis can be performed even if an R component image, not a G component, is extracted and associated, and the processing described later is performed.

<Porphyrin analysis of square plugs>
In porphyrin analysis, a region to be analyzed is selected from polygonal, circular, elliptical, etc., from the front face image taken by receiving visible light under ultraviolet (UV) illumination, and porphyrin analysis is performed within the selected region.

  Here, a specific example of porphyrin analysis will be described with reference to the drawings. FIG. 5 is a diagram showing an example of a porphyrin analysis procedure. First, when selection of a region to be subjected to porphyrin analysis is received from the input image (S11), an R component image is extracted from the RGB components of the selected image region (S12).

  Next, the R image obtained in S12 is smoothed (S13). Here, for example, when the entire face is contained in 1944 × 1944 with an 8-bit image size, the smoothing filter size is preferably 2 to 25 pixels in both the vertical and horizontal directions.

  Next, fluorescence enhancement is performed from the difference between the R image obtained by the process of S12 and the smoothed image obtained by the process of S13 (S14). Specifically, a difference is performed by “smoothed image−R image × a (a is preferably 0.5 to 1.5)” to extract a fluorescent region (a region shining red strongly).

  Further, the difference image is binarized (the binarization line is preferably 30 to 70) (S15), and the fluorescent part is extracted (S16). Here, the number and total area of the fluorescence are calculated (S17), and the extraction region is colored with a color different from the skin color such as red or green in the original image (S18).

<Wrinkle analysis>
In the wrinkle analysis, a region to be analyzed is selected from polygonal, circular, elliptical and other shapes from the left and right side face images taken with flash, and wrinkle analysis is performed in the selected region. Specifically, the number of wrinkles and the total area are digitized and the extraction region is colored.

  Here, a specific example of wrinkle analysis will be described with reference to the drawings. FIG. 6 is a diagram illustrating an example of a wrinkle analysis procedure. First, when selection of an area to be subjected to wrinkle analysis is received from an input image (for example, an 8-bit image with all faces included in 1944 × 1944) (S21), the selected image area is selected. The R component and G component images are extracted from the RGB components (S22).

  Next, a difference image between the R image and the G image obtained in S12 is acquired (S23). Specifically, “R−G × R_ave / G_ave × a (a is a difference calculation formula of RG). 0.7-1.5 is preferable) (_ave indicates an average value) ". Next, the distortion of the RG image obtained by the process of S23 and the distortion of the G image obtained by the process of S22 are corrected (S24). Specifically, for example, distortion correction is performed using a Gaussian filter or the like. At this time, the cut-off frequency is preferably 3 μm to 30 μm.

  Next, wrinkle enhancement is performed using an image (RG image, G image) whose distortion has been corrected by the differential filter (S25). Specifically, filtering is performed using 5 to 20 pixels as a reference for the image size. Thereby, the wrinkles of the corners of the eyes are long and it is possible to extract a portion that is shaded in the horizontal direction.
