Camspeed, benchmarking your Windows Phone 8 camera
Ever wonder how fast your Windows Phone 8 camera is? CamSpeed is a Windows Phone app that will put your Windows Phone 8 camera through a battery of tests and tell you just that. CamSpeed also taps into the Sofica (opens in new tab) benchmarking database not only to publish your results but also to pull numbers from other devices for comparison. CamSpeed doesn't test your camera's image quality but rather the speed it launches, focuses, and captures images.
CamSpeed will maintain a history of your tests and let you share your results on Twitter. CamSpeed isn't going to appeal to everyone but if you're looking for a simple way to test your camera's speed, CamSpeed should fit the bill.
The user interface for CamSpeed is fairly simple. You have a Test Page to start the camera test, a History Page to view your testing history, and a Compare Page to show how your camera measures up.
To test your Windows Phone 8 camera just hold it steady, focusing on one point and tap the test button. CamSpeed will test the speed of opening the camera, focusing, capture speed with and without the flash, and closing the camera. The test takes just a few seconds and when all is said and done you'll get a test summary report that shows your ranking, score with/without a flash, test conditions, and camera information.
The test will be added to your History Page and reflected on the Compare Page based on the lighting conditions. There is a "Compare On" button that will pull up all the benchmark tests that can be switched from low, normal and bright light test results. Again, CamSpeed does not grade the cameras on image quality.
We had interesting results in testing CamSpeed with the Nokia Lumia 920 and HTC 8X. Speed wise, the 8X performed better than the 920. Low light testing had the 8X scoring a 346 while the Lumia 920 scored a 255. Normal lighting the Lumia 920 scored a 320 while the 8X scored a 485. Unfortunately it was a rainy, overcast day so the bright light test was not possible.
How does that compare to other devices? Normal light tests show the Sony C6603 tops with a score of 1090. The LG Nexus 4 takes the top spot in low light tests with a score of 852.
Again, CamSpeed isn't going to appeal to everyone but if you're curious how your camera performs speed wise it's worth checking out. CamSpeed is a free app for your Windows 8 device and you can find it here (opens in new tab) in the Windows Phone Store.

These devices use a 'technically' higher resolution sensor than the pixel count of the saved images. Nokia uses the additional information to process/create the 8.7mp image that is stored to the device. This inherent processing (not sure what % happens in hardware) will create a 'slower' result from a test like this for several reasons.
1) Shutter is open longer, ie the higher ISO modes
2) Even in lower ISO modes shutter is open longer for more data
3) It is also pulling in more pixels than a traditional 8mp camera which DOES require additional processing.
To test 'camera' speed it would be better to test things like 'burst modes' and video/streaming performance of the camera, not just how long it holds the shutter open for a normal shot.
We have been doing some interesting testing with the new Nokia 928, and the image performance in our curve of lighting conditions is rather impressive. Even pulling in images and data from a night sky image that the human eye cannot discern. In daylight and bright or shifiting brightness images, the normal digital tearing and noise is on par with several of our 8mp and 12mp DSLR cameras, and considering the actual imaging sensor size difference, we were rather surprised, even expecint a good performance from the 928.
Nokia has done a good job with a sensor pulling in more pixel, the OIS allowing for longer exposure times, and the final imaging processing that happens automatically for the user is a brilliant mix for any imaging device, let alone a phone. The 'stored' data for the image also doesn't have the compromises that you get with the iPhone or other devices like the S3/S4 where their 'autofix' that happens during the shot destroys the raw data.
To get an image from other cameras like the S4, you can use some of the Nokia techniques, but it requires post processing the 13mp image down to 2-4mp for the final image. The same is true of an iPhone 5, but again you are going to end up with a saved image of 2-3mp just to offset the internal processing the Nokia sensor is doing automatically.
