An image processing apparatus is disclosed that includes an image processing unit section and an information processing unit section. The image processing unit section includes an image scanner that performs an image processing function and a SDK application that expands and controls the function of the image processing apparatus. The information processing unit section includes an operations panel that selectively performs operations between a basic application and the SDK application and a MFP service that transmits an instruction signal to the SDK application so as to control the image scanner in accordance with the operation on the operations panel. The information processing unit section confirms the corresponding relationship between the MFP service and the SDK application when the image processing apparatus performs a starting process and makes the SDK application correspond to the MFP service in accordance with the confirmation results.
