Optical Image Stabilization

An optical image stabilizer (OIS) is a mechanism used in a camera camera that stabilizes the recorded image/video by varying the optical path to the sensor. This technology is implemented in the lens itself, as distinct from in-body image stabilization, which operates by moving the sensor as the final element in the optical path.

Seeing is believing, and this video really emphasizes the differences between taking a video with the iPhone 6s, a device that lacks OIS, and the iPhone 6s Plus, which features OIS built in.

And here’s a other video I took with my iPhone 6s Plus while walking on a broken ground.

A copy of your data

3 07 2018

At a Wall Street Journal conference in 2010, Steve Jobs talked about the responsibility tech companies have to protect user privacy.

“No, Silicon Valley is not monolithic. We’ve always had a very different view at privacy with some of our colleagues in the Valley. We take privacy extremely serious. Privacy means people know what they’re signing up for. In plain English and repeatedly. That’s what it means. … I believe people are smart and some people wanna share more data than other people do. Ask them. Ask them every time. … Let them know precisely what you gonna do with their data.”

Bigger than bigger

26 06 2018

Apple embraces expanded iPhones

It was in 2014 when Tim Cook announced the iPhone 6 with a 4.7” screen and the iPhone 6 Plus with a 5.5” screen. Older iPhone models were 4“ on the diagonal.

Images of the new iThings flashed behind Tim Cook with the slogan “Bigger than bigger”.

Why did Apple switch to bigger screens?

Part of the reason Samsung went the successful way of bigger screens is because many customers – especially Asian customers – often do not have home computers, relying on their phones for their computing and Internet access. There is greater demand for the phablet market. And this makes definitely sense because you save the costs for a second device and can take your “pocket computer” always with you.

When Apple released the iPhone X in 2017 the company was quick to note that the iPhone X came with a 5.8-inch screen, but the phone itself was nearly the same size as the iPhone 8 with its 4.7-inch display.

Now looking ahead, Apple is rumored to release a follow-up to the iPhone X with a 5.8” display. Another iPhone with a 6.1” screen could sit alongside the 6.5” iPhone Japanese website Macotakara and others have tipped.

Pros of a 6.5” iPhone
with a full screen display like the X

• Relaxed reading

• Possibility to implement split-view

• Movies and photos look better

• Tapping is a more accurate experience

• More content of websites is shown

• Games look bigger and better

But there are limits

Smartphones with housings bigger than that of the iPhone 8 Plus (6.24” x 3.07” x 0.3” / 158.4mm x 78.1mm x 7.5mm) or heavier (7.13 ounces / 200g) won’t be accepted by the majority of customers.

and why we should ignore most of them.

Smart phones are not only defined by their specs. When it comes to iPhones and their rivals they most often don’t matter nearly as much as some manufacturers may want you to believe. The problem isn’t limited to the manufacturers. More important are the news spread by tens of thousands of tech bloggers and lots of unbiased online magazines.

Self-appointed experts most often still don’t get it right when they ask “Which … is better?”, show us the specs, tell us that “The winner is …” and ridiculously enough ask “What’s your take? Leave a comment”.

The only way to get an entire picture of devices is to look at hardware and software. It’s an entity. The operating system for example mainly determines the energy consumption of a device. If it’s optimized a battery with less energy may last longer than the one with a better specification. A shining example is iOS 11 in a liaison with an iPhone 8. It lets the 8 (1,821 mAh battery) run 2 hours longer than the iPhone 7 which sports the bigger battery (1,960 mAh battery).

Camera …

Albert Einstein’s saying

“Not everything that counts can be counted, and not everything that can be counted counts.”

is so true for the megapixel discussion.

Cameras with more megapixels usually sacrifice image quality in certain ways. Normally when you pack so many pixels so close together, it creates artifacts called “crosstalk”: inaccurate colors and noise in your images.* Apple’s team worked on new techniques to maintain image quality and size despite the extra megapixels, including a technology called deep-trench isolation, which separates photo diodes and helps to maintain accurate, precise colors. The image quality is a matter of optimizing the processing of a large number of information taken by the camera and its sensors.

Processor …

The same situation applies to many other specs, like processors. The Samsung Galaxy S9 has a 10nm 64-bit Octa-Core Processor 2.8GHz + 1.7GHz, 64 bit processor.

Some fanboys say “Wow!”

other not tech-savvy users ask What?.

(You should hear the rising tone and the keen sound when they ask “What?”.)

Nobody knows what these processor specs mean in every day life when using Google+ or surfing through the Web. Sure, the device is fast but none of the rivals are slow.

And the iPhone 8 has a A11 Bionic …

Whatever. What we know so far is that it crushes the rivals by far but does it help when I read my mails or check my bank account? Definitely not but AR, VR, and ML are coming. A beast may help. But even a beast has to take the existing hardware into account. Optimization is the keyword here as well.

What you don’t find in a spec table …

The build quality, the design, the UX, the ease of use, the timeframe the operating system is maintained, the pros and cons of the environment in which a device runs, the reselling price, the compatibility with devices of other family members, the ability to install company specific apps in the context of BYOD, etc. And last but not least the manufacturer’s commitment to keep our planet green, blue, and healthy.

Summary …

At the end of the day there is a purchase decision if you don’t want to go back to using smoke signals. It’s a complicated matter and it’s always up to you. All big manufacturers make good devices so forget the spec sheets and think about your priorities.

One more thing …

Steve Jobs made this belief of Alan Kay to one of the core principles of Apple:

“People who are really serious about software should make their own hardware.”

It helps to boost the user experience.

Simple wallpapers

12 06 2018

and their relation to iOS development.

Distracting wallpapers? Not on my iPhone.

Think about these words of Sir Jonathan Ive, responsible for Apple’s iconic design.

“You have to deeply understand the essence of a product in order to be able to get rid of the parts that are not essential.”

So black is my preferred theme.

If you think about more than just wallpapers you’ll quickly find out that simplicity would also be a nice feature for operating systems.

Every year users and developers all over the world are involved in the vicious circle of bugs and more or less successful attempts to fix them. If somebody would do a cost-benefit analysis of an update I’m not sure about the results.

The irony of this oxymoron is that simplicity can be quite difficult. It’s not about what you can add, but what you can remove.

Does it really make sense to develop what’s technically possible but meaningless in our everyday life? For people with special requirements nobody would call innovative ideas applesauce but there are tens of millions of users just wasting their time with useless features (and bugs).

Customers appreciate bug-free operating systems and apps.

With every iteration of an OS – wether it’s iOS, macOS, Android, or Windows – customers are faced with problems they experienced already years ago.

Apple, just follow Albert Einstein’s saying

Intellectuals solve problems

geniuses prevent them.

Keep it simple like my minimalist wallpaper and focus on finishing products, testing them extensively and delighting customers with bug-free features.

Thanks for taking your time.

Just 3 years

6 06 2018

The release dates of the first Apple Watch was 3 years ago on April 24, 2015.

iOS 12 will be compatible with the iPhone 5s released on September 20, 2013. iOS 12 will be the OS until September 2019. So the OS compatibility is 6 years.

watchOS 5 doesn’t support my first generation Apple Watch after 3 years already.

Apple, I‘m very much disappointed.
