Image processing system and image processing method

An image processing method which repeatedly reads out a set of image data of a plurality of pages from a memory to execute an image processing thereof, the method including the steps of:

• writing the set of image data of original documents of a plurality of pages read by an image reader into the memory in a prescribed page order in turn and reading out the image data written in the memory in turn to execute an image processing thereof;
• detecting insufficiency of empty capacity of the memory during the writing of the image data into the memory;
• holding only the image data of the original documents of one or a plurality of pages stored in the memory and executing a subsequent image processing by utilizing the image data held in the memory;
• and
• executing a prescribed processing for a re-reading of the original documents corresponding to the original documents whose image data is not held in the memory among the set of image data by the image reader in the subsequent image processing.

An image processing system with a memory capable of storing image data of a plurality of pages which executes a writing of a set of image data of a plurality of pages into said memory in a prescribed page order, and repeatedly executes a reading of the set of image data from said memory and an image processing thereof, the image processing system, comprising:

• an image reader for reading original documents of a plurality of pages to obtain a set of image data to be stored in said memory;
• a detector for detecting insufficiency of empty capacity of said memory;
• a first processor which, in the event that the insufficiency of empty capacity of said memory is detected by said detector during the writing of the set of image data into said memory, executes an image processing of the image data of one or a plurality of pages previously stored in said memory without deleting the image data from said memory, and executes an image processing of image data of one or a plurality of subsequent pages while executing a writing of the image data into said memory and a deletion thereof from said memory every page;
• and
• a second processor which executes an image processing of a second set of image data, wherein said second processor executes an image processing of the image data of one or a plurality of pages stored in said memory by reading out the image data and an image processing of the image data of a subsequent page obtained by reading the original document again;
• and
• a third processor for executing a prescribed processing for a re-reading by said second processor.

An image processing system, comprising:

• an image reader for reading image data of original documents;
• a memory which is capable of storing image data of the original documents of a plurality of pages read by said image reader;
• a detector for detecting insufficiency of empty capacity of said memory;
• and
• a controller for executing a writing of a set of image data of the original documents of a plurality of pages into said memory in a prescribed page order, and repeatedly executing a reading of the set of image data from said memory and an image processing thereof,
• wherein said controller, in the event that insufficiency of empty capacity of said memory is detected by said detector during the writing of image data into said memory by said controller, holds the image data of the original documents of one or a plurality of pages stored in said memory and executes a subsequent image processing by using the image data held in said memory, and
• wherein said controller executes a prescribed processing for a re-reading of image data of the original documents corresponding to the image data not held in said memory among the set of image data by said image reader in the subsequent image processing by said controller.
