Abstract

PURPOSE: To save a toner required for copying and to attain easy to see character by generating a histogram representing the frequency relating to the density of a picture data, obtaining the maximum frequency of occurrence and the density when the frequency of occurrence is maximum and deciding the density region whose background is eliminated from the density.
CONSTITUTION: When a command of background elimination is given from an operation section 3, a histogram generating means 4 generates a histogram representing the frequency of occurrence relating to the density of a picture data and a maximum value detection means 5 obtains a maximum frequency of occurrence and the density when the frequency of occurrence is maximum based on the data of the histogram. An elimination range decision means 6 decides the density region whose background is eliminated based on the maximum frequency of occurrence and the density when the frequency of occurrence is maximum obtained by the detection of the maximum value and a mask means 7 discriminates whether or not the picture element of the picture data is within the range of density whose background is to be eliminated and the background is eliminated when the element is within the range. Thus, a toner required for copying the part not requiring the color background of the original is saved and easy to see character is attained.
