Abstract
A device for processing values corresponding to measurement of pixels, includes an input inputting a j th primary density information X.sub.j representing density information of the j th pixel of an image, where the j th pixel includes a part which overlaps the previous (j-1)th pixel. A calculator calculates the j th secondary density information .DELTA.X.sub.j which represents the density information of the part of the j th pixel which does not overlap the (j-1)th pixel, on the basis of at least the j th primary density information X.sub.j and of the previously calculated secondary density information. A memory stores at least one of the j th primary density information X.sub.j and the j th secondary density information .DELTA.X.sub.j. The device can be used in a facsimile system and a data processing system.
