Abstract
An image processing apparatus for inputting image data from an external image input device and outputting the inputted image data to an external image output device after processing the data, the image processing apparatus including a data compression device for compressing the inputted image data by a variable-length data compression method. An image data storing device stores the inputted image data therein. A control device controls the apparatus, such that, when a size of an output image of the inputted image data is larger than a predetermined size, the data compression device compresses the inputted image data by the variable-length data compression method and the image data storing device stores the compressed image data therein, and, when the output image of the inputted image data is equal to or smaller than the predetermined size, the image data storing device stores the inputted image data therein without data compression.
