It’s not the first time that iPhone users complain about the relatively low resolution of iPhone’s camera. Occipital has recently released an iPhone application called ClearCam that turns iPhone’s camera from 2 megapixels into 4 megapixels camera. Presently, ClearCam is only available via Cydia for jailbroken iPhone.
How can ClearCam double the resolution of iPhone camera? In short, it bases on a technique called Super Resolution. By applying this technique, multiple images are combined to form a single image with higher resolution.
ClearCam offers two operation modes: Enhanced and Quickshot. In enhanced mode, ClearCam takes 6 photos in 2.5 seconds and creates a sharper 4 megapixel image with less noise. To create a high resolution image after taking a shot, just tap “Align”, followed by the “Enhanced” button. ClearCam can automatically transform the photo into high resolution and you can then save it into camera roll. I’ve tried this mode. ClearCam really works as advertised and you’ll notice there is a resolution enhancement and noise reduction as you enlarge the photos.
Take a look here. The 1st image was taken using iPhone’s built-in camera application and the 2nd one was from ClearCam with resolution enhancement. Can you spot the difference?
In Quickshot mode, as the name implies, ClearCam only takes 4 photos in 2 seconds. The sharpest one is selected and automatically saved into camera roll.
ClearCam is not a free application but you can get a 15-day free trial after download. If you want to take higher resolution image on iPhone, it’s worth to give ClearCam a shot.
