A control device includes a binarization processing unit which executes binarization processing on original image data using first and second types of binarization processing methods, and a compression processing unit which executes compression processing on the binary image data using one of a first type of compression processing method appropriate for compression of the binary image data generated using the first type of binarization processing method, and a second type of compression processing method appropriate for compression of the binary image data generated using the second type of binarization processing method. When the binary image data is generated using the first and second types of binarization processing methods, the compression processing unit selects the compression processing method according to a number of using times of the first type of binarization processing method and a number of using times of the second type of binarization processing method. |
