Summary:PROBLEM TO BE SOLVED: To obtain a high speed system for converting a gray level source image into a binary intermediate destination image by comparing N scaled source pixel values with N threshold pixel values compared by a controller and allocating a binary value to a destination image. SOLUTION: A memory stores a part or the like of a source gray level pixels. A scaling image source register 208 stores N source gray level pixel values. Simultaneously a threshold register 222 outputs N threshold pixel values out of W threshold pixel values. Each of threshold adjusting switches 216, 218 inputs a threshold pixel value to a threshold register 222. A controller is driven for inputting W threshold pixel values to N adjacent storage positions in the register 222. A comparator 206 compares N source pixel values with N threshold pixel values and allocates N binary values to a destination image.
