The invention relates to an image processing device () for finding corresponding first and second regions in two image data sets of an object. In a first image data set a source line and in a second image data set a corresponding target line are determined depending on reference regions detectable in both image data sets. A first region in the first image data set is projected onto the source line, thereby dividing the source line into two source sub-lines and defining a source ratio as the ratio of the length of one of the source sub-lines to the length of the entire source line. A second region in the second image data set is then determined such that a projection of the second region onto the target line leads to a corresponding target ratio which is similar to the source ratio.

An apparatus for adjusting images is provided. The apparatus comprises an image decomposing unit for decomposing an input image I into high-pass images HP, HP, . . . , HPN and a low-pass image LPN, and an image adjusting values determining unit for determining high-pass image adjusting values &#x3b5;, &#x3b5;, . . . , &#x3b5;for adjusting the high-pass images HP, HP, . . . , HPN and a low-pass image adjusting value &#x3b4;for adjusting the low-pass image LPN. The apparatus further comprises an image adjusting unit for adjusting the high-pass images HP, HP, . . . , HPN using the high-pass image adjusting values &#x3b5;, &#x3b5;. . . , &#x3b5;and the low-pass image LPN using the low-pass image adjusting value &#x3b4;, and an image recomposing unit for recomposing the adjusted high-pass images HP*, HP*, . . . , HPN* and the adjusted low-pass image LPN* into an adjusted image A.
