Also, sometimes the terms blurred and de-focused are used interchangeably, but they aren't. Focus Magic has a feature to detect the amount of de-focusing at selected locales in the image. That de-focusing is measured as a diameter of the local circle of confusion in pixels. An out-of-focus background has a measurably greater amount of de-focusing, while the in-focus parts of the image measure 0 pixels of de-focusing. You might not want to apply Focus Magic to an image where the photographer deliberately used an expensive fast lens to throw the background out of focus. Fortunately, Focus Magic can be applied to feathered selections in Photoshop, to avoid such blunders.
A truly blurred image will measure 0 pixels of de-focusing, while a de-focused image will read an integer number of pixels. In an image containing areas of de-focusing, each de-focused pixel is spread over a "circle of confusion" and, to a certain extent, all of those overlapping circles of confusion can be pushed back to where they were before the de-focusing spread them out.
Sometimes you can see that effect with the naked eye, in which a single bright point of light (say a distant star) has been spread over a circle, and we could mentally "deconvolve" it back to a point. In most out-of-focus images, the process of deconvolution is very computationally intensive, because there are so many overlapping circles. And the amount of information present in the image is limited by the number of pixels in the image.
A de-focused image looks blurred, but it actually has some recoverable information, and the more pixels there are in the image, the more potential information that can be recovered (and the greater the amount of computation required to process it.) Check out the Focus Magic website.
