Apple’s Two Lens System – Next Generation iPhone

At the Daring Fireball’s John Grubers’ most recent episode of The Talk Show podcast, it was revealed that Apple has been working on a two lens system, incorporating it in the next generation iPhone. Gruber states that `the specific thing heard is that next year’s camera would be the biggest camera jump ever and that it is not known what sense it makes but it is some kind of weird two lens system where the back camera uses two lenses and somehow takes it up into DSLR quality imagery’.

The purpose of utilising multi lens imaging system in making up for a smartphone’s small form is the recent development. HTC had unveiled in March, the One M8 with the `Duo camera’ setup using a secondary imaging sensor for depth data. Corephotonics, an amazing start-up which was profiled by Engadget earlier this year has a different approach.

It developed a dual lens module along with two distinct focal lengths, negating effectively, resolution drops connected with digital zooming. While one camera is used for wide shots, the other is used for close-ups and as an additional bonus; the system also provides spatial data for a 3D imagery due to its lens offset.

The Corephotonics System – Two Lenses 

The Corephotonics system, with two lenses, compares images which are taken from both, opting for the clearest pixels for the best overall photo and utilising a lens which only snaps black and white images thereby improving fidelity and enabling additional light. With little information on Apple’s actual progress for its next generation iPhone, it is difficult to say whether a two lens system would be working in the same way as mentioned.

 Nonetheless, the two lens cameras are a new frontier which manufacturers are exploring to improve image quality keeping the devices slim.The most popular camera choice on image sharing site Flickr has been Apple’s iPhone for a long time since Apple has embraced iPhone photography. Individual new iPhone iteration includes tremendous camera improvements with its `S’ updates bringing about the tremendous improvements.

For instance, with the iPhone 4s, Apple introduced an improved 8 megapixel camera which showed a large jump in quality of the iPhone 4 camera and with the iPhone 5s, the company included an improved sensor an aperture of f/2.2, which is a True Tone flash feature with better autofocus along with a new `Slo-Mo’ mode.

Impressive Camera Improvements – iPhone 6 & 6 Plus

The company has also introduced some impressive camera improvements in the iPhone 6 and 6 Plus which include a new Apple designed image signal processor along with Focus Pixels though there is a possibility that even better camera improvements are being saved for the introduction of the iPhone 6s and 6s Plus in the year 2015.

Recently, Apple supplier Sony had unveiled a new 21 megapixel `stacked’ sensor together with ultra-fast autofocus and 4K HDR video and while the 21 megapixel version would probably make its way in iOS devices, there is a possibility that Apple’s next iPhone would be incorporated in the upcoming Sony 16 megapixel sensor which would include the same features.

Next iPhone Killer Camera Will Come with 21MP Image Sensor Made by Sony

Apple Supplier Sony Unveils Updated Stacked CMOS Image Sensor


AppleSupplier Sony, has recently unveiled an updated stacked CMOS image sensor for smartphones, featuring 32 effective megapixels, on-chip phase detection AF and 4K video recording. The chip is said to be 1/2.4 inch type with square pixels which measures about 1.12um x 1.12um each with video of up to 4K resolution available with HDR function which is also available in still mode. Sony’s previously introduced HDR movie feature now makes its way to this chip.

The sensor utilises a backside illuminated configuration which was earlier introduced by Sony known as Exmor RS with layer of signal processing circuits beneath a layer of backside illuminated pixels and boasts of a total of about 192 AF points with signal processing which is incorporated in the image sensor.

The on-sensor phase tends to detect autofocus and processing eventually resulting in faster and a much accurate autofocus together with improved subject tracking. A mention is also made in a press release of another upcoming sensor, which is a 16 MP stacked sensor having phase-detection AF which would be coming up by the end of the next fiscal year and the IMX230 unit would be shipped by April 2015.


IMX230 Sensor – First CMO Sensor

Apple has been using Sony sensors for its iPhone and iPads and hence it is likely that Sony’s stacked sensor technology would be used in the iOS devices in the near future. The 21 megapixel Exmor RS IMX230 sensor is created with a chip which stacks a pixel section with a circuit section on top of one another enabling Sony to build improvements in each aspect of the individual sensor resulting in dramatic improvements.

Since 2012, Sony has been stacking sensor technology though the latest sensor would be introducing new autofocus together with HDR technology. As per Sony, the IMX230 sensor is the first CMO sensor for smartphone which has plane detection autofocus signal processing providing a much faster tracking of moving subjects which occur instantaneously.

The sensor which supports a full 21 megapixel HDR images and 4K HDR video results in improved lighting in high contrast scenes and the High Dynamic Range – HDR imaging captures images with different exposures together into one image which improves the detail and colour.


Sony’s Plan for 16 Megapixels Version of IMX230


High megapixel sensors are not used by Apple in its iPhone or iPad and Sony has plans in producing a 16 megapixel version of the IMX230 by 2015 which would be just right for iOS devices. There is a possibility that Apple would use the 16 megapixel version of the IMX230 in the 2015 iPhone 6s as well as 6s Plus though it could also be possible that the sensor would not be used till 2016 or later on since Apple tends to utilise older sensors in its devices.

The sensor used in the present iPhone and iPad is not known though camera experts are of the opinion that the iPhone 6 and 6 Plus have the Sony ISX014 sensor which is an 8 megapixel sensor that was first introduced by Sony in October 2012.

Apple Adds UnionPay Payment Option for App Store Customers

Apple has recently announced that App Store has now linked UnionPay debitor credit cards to Apple IDs as payment option for customers in China.

UnionPay in China is the most popular payment card which will provide App Store customers with the option of simple as well as a convenient way of purchasing their apps and customers could link their Apple ID with UnionPay debit or credit card for purchases.

This is significant for both Apple as well as Chinese customers due to the fact the China UnionPay, which is a bankcard network approved by China’s State Council together with the People’s Bank of China have a virtual monopoly and has issued over 4.5 billion cards in China which is available in all cities as well as in overseas markets.

According to recent fourth quarter reports, China with an estimated 100 million iPhone users is Apple’s most important growth market wherein the company generated around $29.8 billion or16% in net sales in the year 2014. Apple’s senior Vice President of Internet Software and Services, Eddy Cue, states that `the ability to buy apps and make purchases with UnionPay cards has been one of the most requested features from customers in China, which is already the second largest market for app downloads and provision is made for users with an incredible convenient way to purchase favourite app with just one tap’.

UnionPay – Bankcard Network 

China UnionPay, as a bankcard network, functions as China’s national inter-bank clearing as well as settlement system, develops UnionPay card acceptance network worldwide, promotes issuance and usage of the UnionPay card and other innovative payment option in order to provide quality, safe payment and efficient services to cardholders.

This network has been extended to all cities as well as rural areas in China. Beside China UnionPay has also helped UnionPay card acceptance in more than 140 countries as well as regions by extensive cooperation with over 400 institutions across the globe. It is also the only interbank network in mainland China which is linked to ATMs.

As per Government regulations, all ATMs and Chines merchants need to use UnionPay in order to process payments in renminbi and foreign credit card companies such as American Express, MasterCard, Visa, which pays UnionPay, a fee for every transaction. Earlier, customers would make payments on the App Store through their telecom operation such as ChinaMobile, through prepayments, or with their credit cards.

Payment Option for the App Store 

The link between UnionPay and Apple seems to be interesting since it comes after reports that Alipay founded by the Alibaba Group with Apple Pay could be considering in striking a partnership and Alipay-Apple tie up could also provide the Cupertino based company a good leverage against UnionPay which is slow in striking a deal with Apple though rumours have been surfacing that Apple had reached a deal with Chine UnionPay which would probably enable users to make payment with what is now known as Apple Pay. However it has not materialized yet but Apple will now be adding UnionPay as a payment choice for the App Store.

Four Things to Know When Buying a Second-Hand Mac

Mac computers have many benefits over PC brands, not to mention the fact that there are plenty of fun things you can do with them. If you are looking for a new Mac computer, chances are you are aware that they can be very expensive. We previously did a piece on buying a Mac for Christmas.

One way to get your high-quality computer on a budget is to buy it second-hand. There are a few different ways to buy a second-hand Mac: direct from Apple, retail shops, and individuals. However, buying a used computer is can be cause for concern, especially if you aren’t sure what to look for. Keep in mind these four tips when you are shopping for you second-hand Mac.

The Exact Specs

When shopping for used computers online on Gumtree, or a refurbished machine somewhere like The Bookyard, it is very important that you pay attention to the descriptions. Vague listings aren’t necessarily a red flag, but the users that post the exact specs of the computer are much more reliable.

If you see a well-priced Mac but the description is not very enlightening, it may be worth it to email the owner and ask about the details. The most important things to know are the year it was made, the RAM memory capacity, hard drive storage, and information about the Mac’s graphics card. You can look these things up yourself if you have your hands on the actual Mac by clicking the Apple icon, clicking on “About this Mac”, and finally clicking on “More Info”. The box that pops up will lists all of these specs and more.

The Screen Condition 

Be sure to look closely at the screen of your potential purchase. Turn on the computer so that the light illuminates any potential cracks or dead pixels. If you have no way to check out the computer for yourself, ask for pictures that show the screen illuminated. If the screen is damaged, you will be able to tell just by looking at it. Replacing a screen can be very expensive, so unless you are getting a really great deal overall, you should seriously consider moving on to another Mac.

Quality of the Body

Whether you are buying a laptop or a desktop Mac, the body surrounding the screen can be indicative of the condition of the computer. Inspect every part of the metal body, looking for dents, scratches, or any other imperfections. Usually, small imperfections are not a problem unless you prefer aesthetically for your Mac to be pristine. In fact, little issues like this can often mean a deep discount. However, anything more than one or two tiny blemishes might spell out issues later and poor care of the machine in the past.

If it Can Be Charged 

Some people try to get rid of their Mac because it has lost the ability to hold a charge. Don’t fall into this trap! Always check for a good charging speed before buying. It’s possible that the issue could lie in the charger itself, which is a cheap fix. But you always want to be sure that it isn’t the actual computer itself.

By checking these things you are far more likely to end up with a good deal than a dud.

Apple Patent Reveals Method of Attaching Sapphire Cover Glass to iPhone

Apple’s Patent – Ceramic Cover for Electronic Device Housing

It has been reported that though Apple had not introduced the rumoured sapphire displays with its updated iPhone 6 and 6 Plus smartphones the company is working hard in bringing about a solution for the future according to the latest Apple patent published by the U.S. Patent and Trademark Office which describes methods of attaching sapphire cover glass to the iPhone.

 Though the patent focuses on attachment methods, it does not indicate potential use of sapphire in electronic devices. The patent describes the use of either sapphire or zirconia which has been titled `Ceramic cover for electronic device housing’, both in crystalline type, to obtain appropriate transparency levels.

 Past inventions of Apple’s dealing with sapphire usually dealt with material production, and the ceramic cover housing patent explains in details the methods of fixing the ceramic cover housing on the handset indicating that instead of using adhesives which add extra thickness to the overall build, an attachment like mortise and tenon joints could be used.

In a single embodiment , the laser ablation technique has been adopted to carve out recesses in a sheet of sapphire which is specified between -.3 mm and 1.0 mm in thickness and a jet of fluid enables it to cool the material carrying away ablated ceramic which could resettle into a freshly cut recess.

Need for Specific Embodiments

Fixing the sapphire to the device housing requires Apple’s usual shock resistant thermoplastic peripheral side members, the thin black buffer zone which is seen on all iPhone and iPad model. Specific embodiments is needed for the peripheral material to hold the housing, the similar design seen in iPhone 6 while others look to cover areas which would remain exposed like the iPhone 4 and 4S.

The sapphire cover has dovetail recesses ablated into it while corresponding angled tenons are integrated together with the peripheral side member and when joined or moulded together in some cases, the components tend to create mechanical interlock providing substantial gap free construction. The peripheral member is made of a ceramic strengthen composite probably using ceramic fibres or particles mixed with polymers wherein these peripheral bodies could be disposed in one or two layers.

Patent Application – Inventor, Kelvin Kwong

Detailed in its patent filing the tech giant company is sinking assets in its sapphire display cover for its flagship smartphone product line. As per the invention, the use of sapphire or zirconia in crystalline form is used though Apple is likely to use sapphire, keeping in mind bet on the material with failed $578 million investment in GT Advanced.

The patent also gives further details with regards to alternative processes in achieving largely a similar design together with moulding techniques, secondary designs and exemplary implementation. Credits of its sapphire iPhone cover patent application go to Kelvin Kwong as its inventor which was first filed for in May 2013.

As with all Apple’s patents and it application, it is yet unknown when and if the said technology indicated would be making its way to the final product. We could wait for more updates coming from these quarters.
