Abstract:
When image data of an original document is detected to include specific information indicating outputting of the original document is prohibited, a selected color component of the image data is applied with concealing processing to make image data of the selected color component to be solid image data. The selected color component is determined based on whether outputting of the original document as a monochrome image is allowed or prohibited.
