Teardown video shows how the Galaxy S9 variable aperture works

15 Mar

The YouTube channel JerryRigEverything recently tore down (or rather tore apart…) the new Samsung Galaxy S9, giving us the closest look at yet at the new smartphone’s camera hardware. So if the still images in the iFixit teardown weren’t quite interesting enough for you, this might just do the trick.

The camera teardown is about one minute and a half long, running from the 3:30 mark until about 5:00. In that time, we get to see the Optical Image Stabilization system demoed and torn open to reveal the magnets inside:

Then, we get really close look at one of the phone’s most intriguing features: the variable aperture. It turns out the system works using a little lever on the side of the housing. So when the phone senses that there is enough light to justify it, it’ll flip this switch electronically and switch from it’s world’s-brightest F1.5 setting to F2.4.

Here’s a very close look at that switch in action:

You can check out the full teardown in the video at the top. And stay tuned, because we’ll be bringing you a full smartphone camera review of the Samsung Galaxy S9 just as soon as we can put a unit through its paces.

iFixit teardown finds Samsung Galaxy S9 Plus difficult to repair, shows dual-blade aperture

12 Mar

The team at iFixit.com has taken apart Samsung’s brand new Galaxy S9 Plus flagship smartphone and given it a pretty low repairability score of 4/10 points. The testers liked the fact that many components are modular and can be replaced independently, but found accessing the battery to be an unnecessary challenge.

The device’s display and glass back also increase the chance of breakage, and make repairs difficult to start. The need to remove the rear glass panel and disassemble the entire phone when replacing the display was listed as another negative point.

During the teardown, the iFixit crew also had a closer look at the smartphone’s 12MP optically-stabilized camera module with 2x zoom. The dual-camera comes as a single unit on a single PCB and with a single connector. Inside, they found the DRAM chips that power the 960 fps super-slow-motion mode.

The S9 Plus main camera uses a variable F1.5/F2.4 aperture, and the close-up images show the design. Instead of a diaphragm-design with several aperture blades, the lens comes with a simpler construction, comprising of two rotating, ring-like blades for switching between its two aperture values.

Head over to iFixit.com to read the full report.

Fujifilm Instax Mini 8 teardown reveals what makes the camera tick

02 Feb

The folks at All About Circuits have published a teardown of the Fujifilm Instax Mini 8 camera, revealing a glimpse at the components found within. Disassembly is simple, and mostly involves removing a series of screws, after which point DIYers are presented with ‘a surprising amount of circuitry.’

Within the camera, All About Circuits discovered a micro-controller, DC buck converter, and a pulse transformer, as well as a xenon flash tube, a light emitter and sensor, and a couple of transformers. This was a surprise to the publication’s Mark Hughes, who said, ‘I expected to find a flash charging and firing circuit similar to the type found in a disposable camera.’

We can forgive All About Circuits for calling the camera the ‘Insta- X Mini 8,’ because we love peering into the inner workings of cameras we wouldn’t have the nerve to dissect ourselves. Details about the hardware are available in the full teardown here.

Teardown reveals Sony image sensors in iPhone 7

24 Sep

Patent and technology consultancy Chipworks has published its iPhone 7 teardown and reveals that front and rear image sensors on the new Apple models are supplied by market leader Sony. This is not too much of a surprise as earlier iPhone models used Sony sensors as well. In its report Chipworks doesn’t say which exact sensor model has been deployed in the rear camera but we know the 12MP chip uses the Exmor RS technology platform, a Bayer RGB color filter array and on-sensor phase detection. Its die size is 5.16 mm x 6.25 mm (32.3 mm2) as measured from the edges of the die stack. 

On the FaceTime front camera the resolution has been increased to 7MP. The Sensor is also a second generation Sony Exmor RS model and measures 5.05 mm x 3.72 mm (18.8 mm2). Chipworks has not treated the larger iPhone 7 Plus model with its dual-camera to the teardown procedure yet, but we would expect both sensors in the dual-camera to come from Sony as well. For now you can find more technical detail in the iPhone 7 teardown on the Chipworks blog.
