Canon Digital Camera Uses Gyroscope, Cmos Sensor For Image Stabilization

Canon Digital Camera Uses Gyroscope, CMOS Sensor for Image StabilizationCanon Inc will release the first compact digital camera equipped with the company's new image processor, "Digic 7," in late April 2016.
There is no manufacturer's suggested retail price for the camera, "PowerShot G7 X Mark II," but, on the company's online store, it will be sold at a price of ¥77,800 (approx US$696, excluding tax, as of Feb 18, 2016).

One of the functions realized by the new image processor is an enhanced image stabilization function. While the previous product stabilizes images with a gyroscope, the new product takes into account the data on the amount of camera shake obtained from the image data collected by the CMOS sensor. Canon calls this function "Duan Sensing IS."

In addition, a "panning" mode was added by using the image stabilization function. The camera instantly analyzes the moving speed of the camera and the moving speed and direction of the subject and calculates the best shooting conditions. As a result, it became easy to take an image with a flowing background while stabilizing the image of the subject.

Furthermore, Canon improved noise reduction performance in a high sensitivity mode, added a function to compensate the diffraction phenomenon at the time of decreasing F value, improved the accuracy of the dark area compensation function (auto lighting optimizer), enhanced the function to track/ detect the subject, etc.

Focusing on function to shoot video with SLR camera

This time, Canon also announced the "EOS 80D" middle-size digital single-lens reflex (SLR) camera and a new lens. For the development of the EOS 80D, the company made efforts to improve usability at the time of shooting video. For example, it realized a smooth AF (automatic focus) to reduce discomfort even at the time of shooting full-HD or 60fps video.

The "Dual Pixel CMOS AF," a mechanism that uses signals from the two photodiodes constituting a pixel of the CMOS sensor for phase-difference AF, has been used for shooting still images. This time, however, the mechanism is also used at the time of shooting video.

For the "EF-S18-135mm F3.5-5.6 IS USM" high-magnification zoom lens, which is expected to be combined with the EOS 80D, etc, Canon employed a newly-developed compact ultrasonic motor, "Nano USM." The company developed the Nano USM in addition to the USM ultrasonic motor, which it uses mainly for high-grade models, expecting that the Nano USM will be used for middle-grade models. Compared with the previous product using a stepping motor, Canon improved the driving speed of the focusing lens by up to 330%.

Also, Canon will offer the "PZ-E1," a separately-sold electric-powered zoom adapter, for shooting video with the high-magnification lens. Compared with the case where the lens is manually operated, it realizes a smoother zoom action. It is the company's first electric-powered zoom adapter to be externally attached to a lens.
