✦ Synopsis

To obtain better informed consent from patients in dentistry, the state of the disease and the treatment process are effectively presented by images, and more realistic hard copies are sought. In this research, we propose obtaining realistic output images by the addition of rendering in the CIE L * a * b * space to the conventional ICC Color Management System framework. The image rendering processes involve a process to expand and compress the chroma and a process to enhance the contrast. To evaluate these processes, dentists performed subjective evaluation tests. We found from the tests that the chroma required adjustments particularly for a high degree of inflammation. The dentist was able to select the processing in view of the test results described above to match his diagnostic conditions and produce hard copies after processing the images to convey the patients condition in an easy-to-understand manner to the patient, other dentists, and technicians.
