Outline of Final Research Achievements |
The present study aimed at clarifying whether priori knowledge necessary for achieving color constancy is innate or acquired, and what the priori knowledge is. We used chicks as subjects. Chicks were raised under a controlled lighting environment, and, their color constancy was tested after one month. Two surviving individuals from a total of six showed the possibility that color constancy was acquired. After that, due to the spread of COVID-19, the animal experiments could not be continued. Therefore, an experiment was conducted to compare differences in illumination light estimations by machine learning neural networks trained under different illumination light environments and those by subjects in psychophysical experiments conducted under the same conditions. As a result, individual differences in illumination light estimation were not clear between the subjects and the neural networks.

Academic Significance and Societal Importance of the Research Achievements |
人間の色恒常性のメカニズムの解明は古くから取り組まれてきた色覚研究の最も困難な課題の一つである。色恒常性の成立には何らかの先験的な知識が必要であるが、人間はこれをどのように獲得するかはまだ明らかとなっていない。本研究のような動物実験によってこの課題に取り組む研究は過去には例がなく、本研究のオリジナルである。したがって、本研究の研究成果は色恒常性の解明の新しい方法を開拓するという意味で、学術的意義がある。また、人間の色恒常性の解明は言うまでもなくコンピュータビジョンの進歩に大きな貢献をする。したがって、本研究の研究成果は社会的な意義を持つ。
