Fujitsu Develops Technology to Gauge Skin Condition with Smartphones

Color reference chart lets users easily and accurately check skin condition

Kawasaki, Japan, May 07, 2012

Fujitsu Laboratories today announced the development of technology that uses a smartphone camera to measure skin condition. In particular, it can accurately gauge skin tone.

The conventional method for measuring the condition of facial skin involved visiting a cosmetics store, where experts used specialized devices to gauge skin tone and condition. Dramatic improvements in the performance of smartphones, however, have opened the possibility of users to analyze the condition of their skin at home using their smartphone cameras. The problem with this approach is that lighting conditions vary from home to home, potentially causing the appearance of the skin tone captured by the camera to differ from the user's actual skin tone.

To address this problem, Fujitsu Laboratories has created a reference color chart that enables users to accurately measure the color of their skin using a smartphone. The smartphone application also allows users to measure how noticeable skin blemishes or pores are (figure 2). As a result, users can easily determine the condition of their skin at home without visiting a cosmetics store. Moreover, companies selling skin care products can reach customers who don't visit stores by incorporating this technology into their online sites to use as a product recommendation tool to boost sales.

Features of the Newly Developed Technology

1. Skin Color Gauge Technology

Even if the appearance of the skin tone captured by the camera differs from the user's actual skin tone due to variations in lighting conditions in each home, compensation technology was developed using the newly created color reference chart to accurately gauge the correct skin tone.

First, users place the chart against their skin and take a photograph using a smartphone (figure 3). The image of the skin also captures the chart's pattern of standard colors (figure 4), which are used to accurately gauge the color data. This enables the tone of the skin in the image to be accurately corrected using the color differentials between the skin and standard colors. In addition, the standard color pattern is arrayed in four quadrants, making it possible to accurately gauge the tone of the skin, even if there is variation in the colors due to the angle of the lighting, for example.

2. Automated Extraction of the Segmentation in the Color Reference Chart's Standard Color Patterns

In order to gauge the color in the process described above, it is necessary to accurately capture the pattern of the standard colors within the chart. Fujitsu Laboratories developed technology that enables an edge of the standard color pattern to be extracted from the digital image, allowing the segmentation of each color within the pattern to be automatically extracted (figure 5). When the photograph is taken, even if hair or a finger partially obscures the standard color pattern within the chart, the segmentation of each color can be accurately extracted.

Future Plans

Fujitsu Laboratories plans to work on making this technology more user-friendly by simplifying the method of capturing the image. The technology is already undergoing field testing, and insights from the test results will be used to make further improvements, with the aim to commercialize the technology within fiscal 2012.
