Abstract: PURPOSE:To obtain an excellent image regardless of reduction ratio by reflecting all the picture elements on an outputted image by performing a linear interpolation after image information in which the average density based on the number of picture elements sectioned according to the reduction ratio is shown by each picture elements and reduced image information is generated. CONSTITUTION:Image information U showing the average density in which the reduced image information from a scanner 1 is calculated for every number of picture element which is close to the inverse number of a reduction ratio in an average density calculation 2a is generated and the information is converted into image information T according to the reduction ratio in a one-dimensional liner interpolation part 2b. At this time, the density of a picture element T is calculated based on the density of the two picture elements which are adjacent to the image information U. After the image information with this reduction ratio is outputted from a main scanning direction reduction part 2 and is threshold processed in a thresholding part 3, the information is outputted via an image output part 4. Thus, by generating a reduced image from the average density of the picture element sectioned into the variable which is close to the inverse number of the reduction ratio and obtaining the image of a set reduction ratio by a one-dimensional linear interpolation method, the density of each picture element is reflected on an outputted image and the elimination of a very small image can be prevented.
