A device, an apparatus, a facsimile system and a data processing system for processing values corresponding to measurement of pixels, comprising: (a) input means (INPUT) for inputting the j th primary density information Xj representing the density information of the jth pixel of an image, said pixel including a part which overlaps the previous (j-1)th pixel; (b) calculation means (1) for calculating the j th secondary density information DELTA Xj which represents the density information of the part of the jth pixel which does not overlap the (j-1)th pixel, on the basis of at least the j th primary density information Xj and of the previously calculated secondary density information; and (c) memory means (4) for storing at least one of the j th primary density information Xj and the j th secondary density information DELTA Xj. ,
