A print data processing apparatus allocates memory from an unused area of memory to one processor out of two processors so that a size of the memory allocated to the processor is equal to a fallback threshold value, and then allocates an unused area of the remaining memory to the other processor.

Print data processing apparatus, print data processing method, and storage medium

An image processing apparatus and method determine whether an error detecting rate of original information extracted from a code image in a read image obtained by reading a sheet on which the code image is formed, is not smaller than a predetermined value. When it is not smaller than a predetermined value, a code image is reproduced from the extracted original information and the code image in the read image is replaced therewith. One example of the code image is a barcode.

Image processing for reproducing code image from original information

When an N-upped paper document was viewed by previewing, visibility thereof was poor because contents corresponding to N pages are displayed collectively. Expansion thereof for improving the visibility makes the operability poor. An image processing device of the present invention includes: a determining unit for determining whether or not image data corresponding to an inputted document is image data of an N-up document in which contents corresponding to N pages (N&#x2267;2) are arranged in one page; a first thumbnail generating unit for generating a first thumbnail of 1-up that is a thumbnail of any of the N pages when the image data corresponding to the inputted document is determined to be the image data of the N-up document by the determining unit; and a display unit for preview-displaying the first thumbnail.
