New Huawei Phone Has a 5x Optical Zoom, Thanks To a Periscope Lens (arstechnica.com)

An anonymous reader quotes a report from Ars Technica: Huawei officially announced the Huawei P30 Pro smartphone today. While it has a new Huawei-made SoC, an in-screen optical fingerprint reader, and lots of other high-end features, the highlight is definitely the camera's optical zoom, which is up to a whopping 5x. Not digital zoom. Real, optical zoom. Space, of course, is at a premium in smartphones. Imagine a smartphone sitting face down, and you would have to fit a vertical stack of the display, the CMOS sensor, and the lens all in about an 8mm height. There is just not a lot of room. But what if we didn't have to stack all the components vertically? The trick to Huawei's 5x optical zoom is that it uses a periscope design.

From the outside, it looks like a normal camera setup, albeit with a funky square camera opening. Internally, though, the components make a 90-degree right turn after the lens cover, and the zoom lens components and CMOS sensor are arranged horizontally. Now instead of having to cram a bunch of lenses and the CMOS chip into 8mm of vertical phone space, we have acres of horizontal phone space to play with. We've seen prototypes of periscope cameras from Oppo, but as far as commercial devices go, the Huawei P30 Pro is the first. While the optical zoom is the big new camera feature, there are four total cameras on the back of the P30 Pro. A 40MP main camera, a 20MP wide angle, the 8MP 5X telephoto, and a Time of Flight depth-sensing camera. The main 40MP camera uses a 1/1.7 inch-type sensor that, when measured diagonally, would make it 32 percent larger than the 1/2.55 inch-type sensors in the Galaxy S10 or iPhone XS.
The P30 Pro also has a new "RYYB" pixel layout, which swaps out the two green pixels in most CMOS "RGGB" sensors for yellow pixels. "Huawei claims it can capture 40 percent more light, as the yellow filter captures green and red light," Ars Technica reports. "Of course, this will make the color wonky, but Huawei claims it can correct for that in software."

Other specifications include a Kirin 980 octa-core processor with 6GB or 8GB RAM, up to 512GB storage, IP68 water and dust resistance, NFC, wireless charging, 40W wired charging, and a 4,200mAh battery. It starts at a price of $1,125.

  1. Dunno about these multi lense cameras. by AbRASiON · · Score: 1

    I own and really really like my fairly new Huawei Mate 20 (non Pro, curved displays can DIE!)

    There's many great features on the phone, I like having an IR port, I have headphone, massive battery, very fast, notification LED.
    It has allmost all the old original Android features that first wooooed me from Apple (which most idiot handset manufacturers are now removing to copy Apple....)

    HOWEVER this phone, replaced a 2015 Samsung Note 5. Yet the camera's much like the p30, cameras everywhere,..... Those cameras? Yeah at least on the Mate 20 regular? They're kinda "ok"

    It's sad that my old old Note 5 can take a brighter, crisper image AND it takes it without fiddling with pro mode stuff. I don't care if the mate can do fancy camera stuff, with patience, I just want a nice point and click to be honest.

    I know they're improving all the time, but seeing that my almost brand new phone produce worse pics than my old one, kinda disappointing.

      These devices are always a pick and choose feature game. There are some features that are too geeky to appeal to most customers, such as the IR port, sure you can use your phone to change your TV Channel, But you will need to find the right software for your phone to match you TV, plus it is a device that will be draining phantom power that may not be used too much. The notification LED while seems like a good idea, and it probably was at the time, however we get too many notifications for it to be handy. You would probably save power by having the light off when there is a notification. Those massive batteries, was because they couldn't hold a charge for too long, and replaceable, not because it was easier for someone to swap out with a charged battery once it was low, but because their reliability often means the battery would be dead and unchangeable within a year.
      Right now phone makers are playing with pro-camera features. However as you pointed out, Pro-features makes average Joe pictures difficult to take. Also for features that seem to stick, Higher resolution, brighter displays, longer battery life, tougher glass, waterproof take up more free space in a device. cutting features available.
      Just remember the Note 7 catching on fire, because it was so jam packed with features, that there wasn't enough space for the battery to expand. I bring this up not to make fun of the Note 7, or the goal of making a full feature device, but to highlight the complications of putting all the features that everyone wants in one device.

      You can control which applications can use the notification LED. Slide the notification a little way left or right so that it reveals the cog icon, tap that and you can disable LED flashing. That way you can reserve the LED for important stuff you actually want to know about at a glance.

      Battery size is largely dictated by screen size. Every phone has to be thin so the screen dimensions determine the battery dimensions which determine the capacity, beyond some gradual increases in energy density.

    That's essentially what your retina does. The red and green photosensors (more accurately called L for "long-wave" and M for "medium-wave") have spectral sensitivity that largely overlap; it is the relative difference that gets resolved into red and green percepts (after a lot of additional processing).

    So, yep, use high sensitivity sensors that mostly overlap in sensitivity, and then correct it in software. That's what your visual system does!

    The zoom is incredible on this thing. Not just the fact that they managed to build it, but that it's reasonably stable in a hand-held device. Normally with 50x zoom you would need a tripod for stability, even if the camera/lens has optical image stabilisation.
