US Patent 7911629 Image resolution and text conversion management

A document management system which can reduce the space used in a storage medium of an information processing apparatus which receives data. It is determined whether or not the resolution of image data generated by an image forming apparatus connected to the information processing apparatus managing image data via a network is higher than a predetermined resolution. If the resolution of the generated image data is higher than the predetermined resolution, the resolution of the generated image data is converted into a low resolution. The resultant image data is registered in association with log information in a storage medium, in the information processing apparatus.
