Image processing server, image processing method, and computer readable storage medium

An image processing method comprising:

• an OCR necessity deciding step of making a decision as to whether OCR processing is necessary or not for image data generated in accordance with drawing commands of a printing job;
• a first data registering step of registering, when the OCR necessity deciding step decides that the OCR processing is unnecessary, text data extracted from a text drawing command of the printing job to a database as text data for retrieving the image data;
• an OCR step of extracting, when the OCR necessity deciding step decides that the OCR processing is necessary, the text data by performing OCR processing on the image data generated in accordance with the drawing commands of the printing job;
• and
• a second data registering step of registering, when the OCR necessity deciding step decides that the OCR processing is necessary, the text data extracted at the OCR step and the text data extracted from the text drawing command of the printing job to the database as the text data for retrieving the image data, wherein
• the OCR necessity deciding step makes a decision as to whether the OCR processing is necessary or not for the printing job in accordance with difference between text data generated by performing the OCR processing on an image generated based on a previous printing job having been processed previously and text data extracted from text drawing command of the previous printing job having been processed previously.

A computer readable storage medium that stores a program for causing a computer to function as:

• OCR necessity deciding unit that makes a decision as to whether OCR processing is necessary or not for image data generated in accordance with drawing commands of a printing job;
• first data registering unit that registers, when said OCR necessity deciding unit decides that the OCR processing is unnecessary, text data extracted from a text drawing command of the printing job to a database as text data for retrieving the image data;
• OCR unit that extracts, when said OCR necessity deciding unit decides that the OCR processing is necessary, text data by performing OCR processing on the image data generated in accordance with the drawing commands of the printing job;
• and
• second data registering unit that registers, when said OCR necessity deciding unit decides that the OCR processing is necessary, the text data extracted by said OCR unit and the text data extracted from the text drawing command of the printing job to the database as the text data for retrieving the image data, wherein
• said OCR necessity deciding unit makes a decision as to whether the OCR processing is necessary or not for the printing job in accordance with difference between text data generated by performing the OCR processing on an image generated based on a previous printing job having been processed previously and text data extracted from the text drawing command of the previous printing job having been processed previously.
