The small size of the image sensor used in a conventional compact digital camera explains why it captures rather flat, unmodulated images. If the image sensor is small, the focal length of the lens is short. The shorter the focal length of the lens, the greater the depth of field - in other words, the greater the range of distances over which the lens can focus.
The prosaic quality of the images captured by an ordinary compact digital camera is caused by the depth of field characteristic of a small image sensor: the lens focuses evenly on everything between the subject and the background, eliminating any cadence within the image. The DP2, however, has an SLR-sized image sensor, so its standard lens is equivalent to 41mm in a 35mm camera, and with an F-number of 2.8, it has a large aperture as well. This means you can utilize the kind of cool natural background-blur effects you would normally expect of an SLR.
