Sharp will release the 5G-compatible smartphone “AQUOS R5G” and “5G mobile router” this spring. Both are the first 5G products for domestic use. What kind of strategy will Sharp launch 5G products? At a briefing on February 17.

How to use a super-wide-angle AQUOS R5G 8K camera?

The company’s keyword for 5G smartphones is “8K”. Sharp CEO says, “With 5G, which enables faster and larger capacity communications,” I want to make it easier for everyone to create 8K video.

Sharp hopes that creating and editing 8K video easily will create a new entertainment service and expand the ecosystem that combines 8K and 5G

AQUOS R5G is the first model that symbolizes such an idea. AQUOS R5G is equipped with the first 8K wide camera as AQUOS smartphone. The out-camera has four eyes: a wide-angle camera, an ultra-wide-angle camera, a telephoto camera, and a ToF camera for depth measurement. Of these, the ultra-wide-angle camera is effective at approximately 48 million pixels and supports 8K (4320 x 7680 pixels) wide shooting.

There are other models equipped with a 48-megapixel camera, but most adopt it for wide-angle (standard) cameras, and it is unusual for an ultra-wide-angle camera to have such a high-pixel lens.

In addition, the AQUOS R5G can shoot 8K video using this ultra-wide-angle camera. This is exactly what 5G smartphones do. If higher-speed communication becomes possible with 5G, large-volume data such as 8K video can be easily shared via mobile lines. According to Sharp’s explanation, when calculating the upstream speed at about 360 Mbps, one minute of 8K wide video can be transmitted in 6 seconds, and a photo of 48 million pixels can be transmitted in 0.2 seconds. “5G will change visual communication at once,”

8K videos can also be output and enjoyed on 8K TVs, including Sharp products. Sharp CEO says, “You want to watch 8K videos that exceed the level of smartphones on 8K TV.” However, those who have 8K TV are limited.

The AQUOS R5G has a 6.5-inch display with a resolution of QHD (1440 x 3168 pixels), so even if you watch an 8K video on the AQUOS R5G, you may not notice the impact.

Sharp also understands this point, and “8K Focus Playback” was prepared as a “new function that all customers can enjoy even if they do not have an 8K compatible TV or PC”

When playing back a movie shot in 8K, the camera automatically identifies the subject or animal as the subject and zooms up.

“It achieves the same thing as human vision and cognition,” says Sharp CEO “Humans are unconsciously repeatedly raising and lowering the area of interest.

The subject is switched and played back so that the interest is switched,” Sharp CEO says, “The resolution of 8K video is 16 full high-definition video and 36 for high-definition video, so even if the subject is enlarged, sufficient resolution remains.”

“AI Live Story” evolves into “AI Live Story Pro,” which extracts the optimal scene from a video shot and creates a 15-second digest movie. Although it cannot be created from 8K video, it can now be split into multiple frames and use zooming. All wide-angle, ultra-wide-angle, and telephoto cameras support AI Live Story Pro. AQUOS R3’s AI live story was for ultra-wide-angle video-only cameras, but with AQUOS R5G, the same function can be used with wide-angle and telephoto cameras, which means that the range of
enjoying videos has been expanded.

Four-lens camera also improves camera convenience

AQUOS R5G’s four-lens camera is a combination that can be found in other companies’ products, but “It is not a number (of lenses) but a combination of four cameras to create a new experience, you can shoot more scenes with optimal image quality” A new telephoto camera with a focal length (35mm equivalent) of 52mm is compatible with 2x optical zoom.

The 48-megapixel ultra-wide-angle camera incorporates a “quad Bayer sensor” that increases sensitivity by treating four pixels as one pixel, and is actually stored at 12 million pixels.

Sharp CEO appeals from ultra-wide angle 0.7 times to telephoto 2 times “highly sensitive 12 million pixels in all zoom range”. The wide-angle and telephoto cameras also support optical image stabilization.

By using a ToF camera, Sharp CEO says that “You will impressive pictures can be taken” with blurred backgrounds for both images and moving images. Apps that support Google’s AR platform “ARCore” will also be able to use the ToF camera faster. ARCore will be supported by an update after release.

Equipped with a display suitable for 5G

Not only the camera but also the display pursued “performance suitable for 5G”. Sharp CEO believes that “5G lines will be the fastest than any other environment,” said “Various video services will be smartphone-first (more opportunities to watch on smartphones).”

Therefore, we were particular about a large-sized 6.5-inch display. “The 6.5-inch, 50cm away, is physically the same size as the 65-inch, 5m away. The smartphone display, which is 6.5 inches, is the largest first display.”

The brightness of the backlight has been improved by 12% from AQUOS R3, and the highest brightness for smartphone AQUOS is 1000 candela. “Even in direct sunlight, it can express highly visible content that is as competitive as outside light,” Kobayashi said.

In addition, the sensor detects the surrounding light environment and expresses the content with the most appropriate color and brightness, and “HDR” controls the backlight according to the environment to suppress overexposure and underexposure. Enhancer “is also newly adopted. The HDR enhancer brightens the screen when needed, thus contributing to low power consumption.

The Pro IGZO display familiar to AQUOS R3 has been inherited, and the 1 billion color expression, 120 Hz drive, and idle stop ”that keeps updating once a second when there is no screen update are also alive.
