Fujifilm’s X-Trans CMOS Sensor Receives National Invention Award

Phase-detection autofocus pixel and RGB color filter array layout of an X-Trans CMOS 4 image sensor. The ZA and ZB pixels shown each form one half of a phase-detection AF pair.

FUJIFILM Corporation was awarded the Minister of Education, Culture, Sports, Science and Technology’s Prize for “Invention of digital imaging device using color filter array with low periodicity” on May 23rd at the National Invention Awards (sponsored by the Japan Institute of Invention and Innovation). Announced that it has received the “Invention Achievement Achievement Award”.

The X-Trans CMOS sensor technology installed in the company’s mirrorless camera “FUJIFILM X-T3” etc. was evaluated. According to the company, it was awarded because it was evaluated as contributing to the promotion of science and technology and the development of the industrial economy.

The company’s image sensor is inspired by the structure of a photographic film in which silver particles are irregularly arranged, and employs a low-periodicity color filter array with 36 x 6 pixels as one unit.

Color moiré can be suppressed without using an optical low-pass filter, and the original resolution of the lens can be derived, and color information can be correctly acquired by arranging the three elements of light of red, green, and blue on the same line in the horizontal and vertical directions. It is possible to reproduce the original color of the subject.

National invention commendation is a system to commend original inventions and other outstanding inventions for the purpose of contributing to the improvement of science and technology and industrial development in the country. Among them, the Minister of Education, Culture, Sports, Science and Technology Award is given to “inventions etc. that have excellent scientific and technological progress and have remarkable implementation effects.” The “Invention Achievement Achievement Award” is presented to the representative of a corporation that receives a special award including the “Ministry of Education, Culture, Sports, Science and Technology Award”.
