2021 LT10 | Talking about the help of Canon eye control focusing technology to shooting

Leading Technology 10 (hereinafter referred to as LT10), a special column of Zhongguancun Online at the end of 2021, aims to select the top 10 leading technologies of the year based on the contribution to promoting the development of the industry, representing the mainstream application technologies formed in the next year or even years, and landing on the product itself as the benchmark, so as to lead the sustainable development of the industry.

Zhongguancun Online believes that Canon's eye control focusing technology launched in 2021 can participate in this final selection. This technology can quickly lock the shooting subject during shooting, making the switching of focus area more rapid and convenient. It opened a new chapter of human-computer interaction of professional imaging equipment, and greatly improved the success rate of shooting.

1、 Technical principles and functional characteristics

Canon professional WeChat order released this year camera EOS R3 It is equipped with a technology called eye control focusing. First of all, eye control focusing technology is not automatic focusing for human eye recognition. Eye control focusing refers to controlling the change of focusing area through the rotation of eyes. In short, as long as the user stares at the subject, the camera can focus on it, just as the camera can understand the intention of the photographer,

The eye control focusing structure is that an infrared LED lamp is installed in the viewfinder to illuminate the cornea through the LED lamp. The sensor detects the infrared reflected light of the cornea to identify the pupil position, and supports naked eyes and photographers wearing glasses. The detected line of sight position will display eye control marks. The photographer can confirm the eye control position as the focus position by simply half pressing the shutter button, which is very fast. After the photographer locks the subject with the line of sight, the camera can also identify the subject efficiently and automatically optimize the focusing position.

How to realize eye control focusing technology

After locking the subject, it can also identify the subject efficiently, and automatically optimize the focusing position.

When using eye control focusing, it is necessary to calibrate it first, so that the eye control focusing technology can better serve specific photographers and be targeted for optimization.

In fact, EOS R3 is not Canon's first camera equipped with eye control focusing technology. This technology was used on the film SLR EOS 5 QD in 1992, and later EOS 3 was also equipped with eye control focusing technology. Now, based on more powerful image processing technology and speed, combined with the rich display functions of the electronic viewfinder, the eye control focusing technology used on EOS R3 is faster, more accurate, and more practical. It can be regarded as a new technology, not a simple performance upgrade.

2、 Practical help for shooting

What are the advantages of eye control focusing technology? It can quickly change the focus area. Although most current cameras support selecting the focus area by touching on the screen, even if it is so convenient, people still need to stop shooting to free up their hands. Many times, they miss the best shooting time because of operating equipment.

The photographer can switch the focus area only by shifting the line of sight

Eye control focusing does not need to interrupt shooting, and the photographer can complete the switching of focusing area only by shifting the line of sight in the viewfinder. With such rapidity and convenience, photographers will not miss any fleeting wonderful moments. This is undoubtedly the most important thing for news photographers, sports photographers and ecological photographers who need to record decisive moments.

3、 Impact on the imaging industry

All along, practitioners in the imaging industry have made unremitting efforts to achieve intelligent, fast and accurate focusing. Canon's eye controlled focusing technology has raised the focusing technology to a new height, bringing revolutionary innovation to the human-computer interface of imaging equipment. It provides new ideas for the entire imaging industry, and promotes the technological innovation of other brands in focusing and other imaging technologies. The most rare thing is that this technology is not just cool, but can bring real help in shooting, and is easy to use.

Eye control focusing technology promotes technological innovation in the industry

For the photographer, the eye control focusing technology simplifies the focusing process, greatly improves the shooting efficiency, and will not miss the best shooting time because of operating the camera. Imagine a specific shooting scene where the subjects A and B are located on different focal planes in the picture. After focusing on A and shooting, just move your line of sight to the position of B to complete the switch of focus. Is it very convenient and efficient.

Conclusion: Being elected as a member of LT10 means Canon's eye control focusing technology has core technology and leadership to lead the development of industry. Relying on technical R&D strength, technical innovation ability and technical expansion potential, we will continue to provide users with high-quality products with faster operation speed, better efficiency and better experience, and continue to promote industrial development.
