iPad mini Review
by Anand Lal Shimpi & Vivek Gowri on November 20, 2012 6:10 PM ESTCamera
The iPad mini features a 1.2MP front facing FaceTime HD camera and a 5MP rear facing iSight camera. The rear camera shoots photos at 2592 x 1936, the same resolution as the 4th generation iPad. Both of the new iPads have the same f/2.4 lens, however the mini features a wider field of view thanks to its shorter 3.3mm focal length.
| Camera Comparison | |||||||
| Sensor | Resolution | Compressed JPEG Size | Aperture | Focal Length | |||
| Apple iPad 4 | 5MP | 2592 x 1936 | 3.4MB | f/2.4 | 4.3mm | ||
| Apple iPad 2,4 | 0.7MP | 960 x 720 | 344KB | f/2.4 | 2.0mm | ||
| Apple iPad mini | 5MP | 2592 x 1936 | 3.1MB | f/2.4 | 3.3mm | ||
| Apple iPhone 5 | 8MP | 3264 x 2448 | 3.1MB | f/2.4 | 4.1mm | ||
| Apple iPod Touch 5 | 5MP | 2592 x 1936 | 3.1MB | f/2.4 | 3.3mm | ||
Still performance of the rear facing camera is very similar to the 5th generation iPod Touch, and not as good as the 4th generation iPad.
The front facing camera is also similar to what you find in the iPhone 5 and 5th generation iPod Touch:
| Camera Comparison | |||||||
| Sensor | Resolution | Compressed JPEG Size | Aperture | Focal Length | |||
| Apple iPad 4 | 1.2MP | 1280 x 960 | 426KB | f/2.4 | 2.2mm | ||
| Apple iPad 2,4 | 0.3MP | 640 x 480 | 105KB | f/2.4 | 1.8mm | ||
| Apple iPad mini | 1.2MP | 1280 x 960 | 372KB | f/2.4 | 2.2mm | ||
| Apple iPhone 5 | 1.2MP | 1280 x 960 | 400KB | f/2.4 | 2.2mm | ||
| Apple iPod Touch 5 | 1.2MP | 1280 x 960 | 406KB | f/2.4 | 2.2mm | ||
Performance of the front facing camera is decent, and a significant improvement compared to the iPad 2 (you can see comparison shots in the gallery above):
Although I'm continually impressed by folks using tablets as their primary cameras at trade shows and press events, I don't believe the same standards apply to tablets as they do to smartphone camera systems. That being said, it's good to see continued improvements here.
Video
The iPad mini shoots 1080p video from its rear camera and 720p on the front. It looks like Apple is borrowing from the iPhone 5's encoder improvements here as video shot with the rear camera is encoded using High Profile H.264 (L4.1) at 17.1Mbps. The improvement in encode quality is possibly unlocked through software/firmware rather than an actual hardware change since this is still running on A5r2 silicon. In our iPhone 5 review, Brian pointed out that the A6 uses the same encode/decode hardware as the A5 but its full capabilities weren't unlocked until the A6. Given that encode quality has also improved on the A5r2 based iPad mini, it would seem that Apple limited earlier designs either due to a lack of time or to stagger its improvements across generations.
The front facing camera shoots baseline video at roughly 10.6Mbps, a huge improvement over the iPad 2 and iPad 3:
Video quality is definitely good enough for web use:

Just give the 7" the 2048 res treatment, and then double the 10" iPad's resolution once again! lol.Seriously though, it involves support on their end for some software changes, hope they follow through. I doubt they would want this mini to always (even the near future) have this resolution.

LCDs in phones are at 440 ppi with some manufacturers testing almost 500 ppi so with a big investment from Apple, doubling the Retina (264 ppi) iPad's resolution would probably be possible within 1 or 2 years. It wont happen though because of reduced battery life and reduced performance on current hardware for a very subtle gain in image quality. It will probably be 5 years before we see 10 MP+ tablets because battery life and light weight are more important. Mobile SOCs also just aren't fast enough. Even with DDR3 next year the iPad will still only have twice the memory bandwidth it had for the iPad 3, not enough to even attempt 4x the pixels. Getting enough memory bandwidth for double Retina in an iPad will require next generation DDR technology or an even wider memory system which won't be viable anytime soon.jecastejon - Wednesday, November 21, 2012 - link
I just hope the "resolution war" on tablets and phones to be over at 400 dpi, but it should be already over at 350 dpi.From the human sight point of view it is basically over. The extra power and resources should go to better frame rates, better graphics and battery life.
Today there are a few ridiculous measurements or also detrimental technology examples going higher every day like the dynamic contrast on TVs or the megapixel war on tiny consumer sensor cameras. They are misleading advertisement.
500 dpi is useless to 99.9% of humans at almost all ages even if the technology allows to go further and further.

It's going to age very fast with that ancient cpu, and only 512mb of memory. Basically the moment the mini 2 comes out with a faster cpu this one will be forgotten and apps won't run on it.tbh seems like a rip off to me. It says something that the main reason I read for buying it is the shape of the screen - you've got to love that a lot to buy something that is all the other ways worse then it's much cheaper competition.

Did you look at the benchmarks? I'm not sure I would say that it is "all the other ways worse then it's much cheaper competition."As a HTC One X user, I can tell you first hand the Tegra 3 isn't the sum of its parts, and the benchmarks that Anand provides proves that.

You actually anticipate developers will drop support for the iPad Mini "the moment" the 2nd generation is released? The 1GHz A5/A5X CPU is also used in the iPad 2 and iPad 3, while the slower 800Mhz A5 is used in the iPhone 4S and 5th gen iPod Touch which will both be on sale into 2014 given Apple's 3 year iPhone and 2 year iPod Touch sale cycles as they move down price tiers. The majority of iOS devices are A5 devices and will be for the next year or 2. The vast majority of apps still support 3rd generation devices and 4th generation device support is even higher. Apple's license agreement guarantees the iPad Mini will get iOS 7 and historically each device runs 3 major OS revisions over it's lifespan, so the iPad Mini will likely get OS updates into 2015. The chances of developers dropping support for 5th generation devices like the iPad Mini in the next year or 2 seem slim.Dribble - Wednesday, November 21, 2012 - link
You can think that if you like but 512mb of ram is already a limiting factor, and the cpu/gpu will start to be come one too as time goes by.This is the world of apple - if it's not new then it doesn't matter, and with the mini you are essentially buying something that's already 1 1/2 years old.

Except its 512MB (megabytes, no mb or megabits) of RAM.... but I know what you are saying. I suppose you should have some concern, but then again Apple - at least for the last few years - has been the best at SoC and even my old arsed iPhone 3GS runs well with iOS 5. It could run iOS 6, though it wont have the best features ... so that should change your mind.Unlike Google/OEMs/phone carriers, Apple supports its hardware and you get more out of the hardware - even when the specs are not "as good" as the competition.

CPU is still ok, GPU the same, but the 512 MB RAM is absolutely something that's a worry. It wasn't enough on my iPad 2 a year ago and it's very annoying in Safari if you have several tabs. And it will only get worse as time moves on. Adding another 512 MB RAM would have cost Apple basically nothing and made the product a lot more future proof (as far as it is possible in this fast-moving segment of a fast-moving industry).karasaj - Tuesday, November 20, 2012 - link
Will it blend?
