Camera megapixels: Why more isn't always better (Smartphones Unlocked)



It's time to forget megapixels as the measure of smartphone camera performance and pick a new yardstick.

Just days ago, Samsung announced the Samsung Galaxy S III, the global, quad-core, Android Ice Cream Sandwich successor to its best-selling smartphone ever, the Galaxy S II.

CNET readers' reactions were mixed, with several comments that the 8-megapixel camera didn't seem too hot.

Rumors of a 12-megapixel camera leading up to the announcement were partly to blame. It's no wonder that some felt that a perfectly good 8-megapixel spec was taking a step back, especially with the 16-megapixel shooter on the HTC Titan II out in the wild, and Nokia's 41-megapixel 808 PureView, a Mobile World Congress stunner.

Despite the fact that 8 megapixels is pretty standard for a high-end smartphone camera these days, one CNET reader described the Samsung Galaxy S III's camera as "so last year." Never mind that at least one high-end phone, like the Samsung Galaxy Nexus, still touts a 5-megapixel camera.

It isn't that 5-megapixel cameras can't be good, even better than phones with an 8-megapixel count lens; or that we're due for another bump along the megapixel scale. It's that to many shoppers, 5 megapixels just doesn't sound as good as 8, even if the camera produces terrific, knock-your-socks-off shots. And well, if 8 is good, then 12 is better.

The dirty secret lurking behind today's 8-megapixel yard stick for high-end status (and what any photography nut will tell you) is that the megapixel number alone is a poor way to predict photographic performance.

For instance, the original Samsung Focus took some lovely shots on its 5-megapixel camera, while the Motorola Droid Razr's 8-megapixel lens creates disappointing pictures. And the 5-megapixel camera on Apple's iPhone 4 beat out some 8-megapixel cameras on the market and delivered good low-light results.

Of course, that's not to say that bigger can't also be sometimes better. For instance, HTC's One X high-performance 8-megapixel smartphone camera boasts rapid shot-to-shot action, and its Titan II takes 16-megapixel shots of solid quality.

So what's the formula for fantastic photos? It involves an entire camera module that includes not just the size and material of the main camera lens, but also the light sensor behind it, the image processor, and the software that ties it all together.

Star Walk  for  $4.99

The astronomy app Star Walk is not a new app but when used on the new iPad it is nothing short of stunning. Star Walk can identify up to 300,000 stars on the iPad’s screen and is ideal for youngsters and adults alike. By simply holding your iPad into the sky, the app labels out the constellations, the solar system, stars, and satellites.

The app also includes a celestial calendar that informs how to plan star gazing by listing events such as full moons, meteor showers and upcoming partial eclipses.

The most interesting feature of the app is the Augmented Reality technique where it overlays data from the app on top of the image (of the sky) as captured by the iPad camera. Using this, user can align the image of the sky with that of the sky in the app.

This helps in pinpointing the position of satellites, finding stars or constellations.

You get the social bragging rights to show off your iPad and how a photo of your current location is overlaid with the app-generated sky, giving you real time results of what is right above you. There are some stunning pictures of the day (sun, etc) that makes for a super high resolution view of a celestial scene.
