Abstract

PURPOSE:To reduce the data capacity of an image obtained by mixing a binary image and a multivalued image to store the image by providing the titled processor with a means for storing binarizing image and a means for storing multivalued image. CONSTITUTION:When an original to be read out by a scanner is constituted of a document and a photograph, a halftone image in the photograph is stored as multivalued data and a document is stored as binary data at the time of storing the image in an external memory 20 to reduce the capacity of the image data itself. The areas of binarizing processing and multivalued processing can be set up by selecting an automatic mode for automatically judging a document by a binary/multivalued data discriminating part 21 and executing the binarizing processing.
