The LUMIX GH series has been highly evaluated in the market for its outstanding video performance and excellent maneuverability unique to mirrorless interchangeable-lens cameras. In recent years, due to the expansion of Internet video distribution, a device capable of producing higher quality images than ever has been required. In this article, we will explain the element technologies that realize the video performance and mobility of the S1H that was developed to meet such demand.

GFX100 is a large format digital camera incorporated with a 102MP image sensor. The combination of the newly developed In-Body Image Stabilization unit and the shock absorption mechanism, packaged inside a compact body realizes outstanding performance for image quality and opens up new possibilities for photographic expression. In this article, we will share some of the technologies which GFX100 is powered by.

SIGMA fp is the world's smallest and lightest lens interchangeable mirrorless camera equipped with a full-size bayer sensor. For stable performance, how to manage the heat during long-time movie shooting was a challenge for us, as the sensor and image processing engine generate heat and might cause overheating. I am going to explain the implementation of heat sink and a heat dissipation coating for achieving both compactness and comfortable long-time shooting.

Canon has developed three zoom lenses in the F 2.8 L zoom lens series for RF mounting. It is equipped with a new optical design, an additional Image Stabilizer function, and a nano USM that realizes high-speed and smooth AF, and plays a role as a next-generation regular lens. This paper describes the features and technical details of the development of these three zoom lenses.

Cultural property photographs that record the appearance of cultural properties that can be lost always require the highest possible resolution at the time of shooting. Even if the information is difficult to read at the time of shooting, it is possible to obtain further evolved information by using a high-definition photographic image after technological progress.

Visual image of early Japanese Railways is hardly obtainable due to the lack of drawings and photographs of the era. Most equipment and materials were imported from western countries, no record was seen how the assembly of cars or laying track or bridge construction were made. The train operation, how many cars in a train, how average travelers took train ride, how freight trains were operated, etc., all are yet unclear. The “Yatoi”, mostly English engineers who worked in Yokohama or in Kobe, took photos for their communications. As the term of them in Japan were two to three years, they wrote reports of their works in the English technical journals with figure for the next job hunting. Photographs then popular were souvenirs for foreign travelers, so the subjects were mostly landscapes and lives in Japan. Fortunately, some large format prints of Kobe or Yokohama taken from hill sides included railway stations. We clarified unknown sides of early Japanese Railways by reading details of photographs taken by Yatoi or as souvenirs.

This report is the result of the project to restore the images from old photographic glass dry plates that had been stored at Yawata Works for 120 years, to turn the images into digital image data. This project was implemented from 2008 to 3 years. When handling old assets such as old photographic glass dry plates, the owner's intention is the most important. Based on a plan based on sufficient interviews with owners, we might develop experimental equipment and solve all owners' requests. This time, we had developed an experimental device that uses a brownie digital camera and a medical illuminated photography stand unit. In addition to realizing no damage to the old glass plates, we succeeded in restoring the image data of 43 million pixels and high resolution image data up to 150 million pixels. In this project, we were able to discover many evidence of World Heritage registration and discover various cultures and technologies of the Meiji era. We hope that this repot will serve as a reference for new research on old photographs.

Historical photographs accurately convey the appearance of the site to future generations, but it is not easy to convey the interests of people at that time and the impressions of those who visited the site. British photographer Felice Bea to, who opened a photo studio in the foreign settlement of Yokohama in 1863 and visited Edo along with the Swiss mission or Dutch consul, had left many photographs of the Edo area. And Heinrich Schliemann, who discovered the ancient city of Troy in 1871, stayed in Japan for a month during the world tour in 1865. He made a five-day excursion from Yokohama to Edo with the invitation of a United States deputy minister and recorded it in his travelogue. In this report, by superimposing the 4 scenes of Beate's photos and the Schliemann’s travelogue, namely,（1）the murder site of foreigners,（2）the panoramic view from Atago-yama,（3）Asakusa temple,（4）tea-house of Oji, we will consider the foreigner’s interest and impression at that time.
