An apparatus for adjusting images is provided. The apparatus comprises an image decomposing unit for decomposing an input image I into high-pass images HP1, HP2, . . . , HPN and a low-pass image LPN, and an image adjusting values determining unit for determining high-pass image adjusting valuesε1,ε2, . . . ,εN for adjusting the high-pass images HP1, HP2, . . . , HPN and a low-pass image adjusting valueδN for adjusting the low-pass image LPN. The apparatus further comprises an image adjusting unit for adjusting the high-pass images HP1, HP2, . . . , HPN using the high-pass image adjusting valuesε1,ε23 . . . ,εN and the low-pass image LPN using the low-pass image adjusting valueδN, and an image recomposing unit for recomposing the adjusted high-pass images HP1*, HP2*, . . . , HPN* and the adjusted low-pass image LPN* into an adjusted image A.
