Easy Human Visual MTF Measurements

Naoyoshi Nameda; Masato Masuya; Yuji Shimizu; Eiichi Hatae

This investigation concerns measurement of the human visual MTF properties using a computer display. At the beginning of the 21st century, 30% of the Japanese population will be over 50 years old. One of the countermeasures for visual degradation is the improvement of displayed pictures. The human visual MTF properties are fundamental data for this improvement. In this paper, easy MTF measurement is discussed in comparison with precise MTF measurement. In the framework of this study, subjects were distinguished in the following way: people over fifty years old are referred to as“aged” and those around twenty years old are called”young”.
