    摘要: 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.

    摘要: In a thermal printing head for use in a facsimile printer or the like, unevenness of printing consistency occurs which is due to temperature variation of the thermal resistor elements and due to the difference in printing data resulting from black record information or white record information of the printing data for the preceding line. A printing pulse control circuit for the thermal printing head stores the information for the preceding line, and applies a printing pulse of smaller pulse width to the thermal resistor elements heated by the black record information for the preceding line and a printing pulse of larger pulse width to the thermal resistor elements not heated with white record information for the preceding line to make uniform black printing consistency for the present line irrespective of the type of printing data for the preceding line.
