PURPOSE:To provide a digital copying machine improved in the read accuracy of a closed loop from a mark sheet original on which the closed loop drawn by a pencil or the like. CONSTITUTION:An image input section 4 stores image data read from a copy original or a mark sheet original to a storage section 2. When a closed loop cannot be read from the mark sheet original, the read density level is revised and then the read of the mark sheet original is tried again. An image processing section 5 processes the image data of the mark sheet original stored in the storage section 2 to generate image data of parts inside or outside of the closed loop and the generated image data are outputted from an image output section 6 and printed out on paper by a print section 7. |
