+Correct images from a digital camera with CCD defects.
+
+Jpegpixi is unique in that it tries to preserve the quality of the JPEG image
+as much as possible. Usual graphics programs decode JPEG images when they are
+loaded, and re-encode them when they are saved, which results in an overall
+loss of quality. Jpegpixi, on the other hand, only decodes the DCT blocks
+(typically 8×8, 16×8, or 16×16 pixel areas) which contain pixels to be
+interpolated, and when it re-encodes them, it uses exactly the same parameters
+with which the image has originally been encoded. These blocks are therefore
+only minimally disturbed, and other blocks remain pixel-by-pixel identical to
+the original image.
