Embodiment Construction

[0053]An embodiment in which the present invention is applied will be described below with reference to the drawings. In the following examples, a program for executing the skin evaluation method of the present invention by a computer is installed on a mobile phone having a fingerprint sensor, and the mobile phone is operated as the skin evaluation device of the present invention. The outline of this embodiment will be described. The skin evaluation program built into the mobile phone is activated, the operator makes the fingerprint sensor built into the mobile phone read the skin image, the skin condition of the input skin image is evaluated by the skin evaluation program, and the result is displayed on the display screen.

[0054] The configuration of the mobile phone is explained with reference to FIGS. 1 and 2 . FIG. 1 is an external view of a mobile phone 1 . FIG. 2 is a block diagram showing the electrical configuration of the mobile phone 1 .

[0055] As shown in FIG...

Abstract

A part of the image inputted (S1) from a fingerprint sensor is segmented (S3), and the fundamental frequency is computed by second-order linear prediction analysis (S5). The sum (S) of the fundamental frequencies in the x and y directions is computed and used as a judgment measure of the texture degree (S7). A predetermined threshold and the measure S determined in S7 are compared, and the degree of skin texture is evaluated to one of three levels (S9 to S17). The ratio between the fundamental frequencies in the x and y directions of the object image is computed and used as an evaluation measure of the texture flow (S19). The image is rotated, and a similar evaluation measure is determined. Based on these measures, the texture flow is judged at one of two levels (S31 to S35). The results of the judgment on the texture degree and the texture flow are displayed on a display screen (S37).

Description

technical field [0001] The present invention relates to a skin evaluation method and a skin evaluation device. Background technique [0002] Healthy and beautiful skin is generally desired by many people. In order to realize people's desire to be beautiful, many companies have developed and sold various makeup and beauty appliances. Because makeup and beauty appliances are suitable for some people and not for others, it is necessary to choose a beauty method that is suitable for each skin type and skin condition of different people in order to give full play to the role of makeup and beauty appliances. Therefore, judging the skin condition is extremely important. [0003] The condition of the skin (sometimes referred to as the epidermis) is usually evaluated on the basis of "texture". Texture refers to the reticular contour line distributed on the skin surface, and is composed of higher parts of "pichus", "skin furrows" between the picchus, and "hair follicles". "Skin te...
