Disclosed is an image reading apparatus including: a reading unit configured to optically read an original and to output image data; an image conversion unit configured to convert the image data into data having a predetermined format; a storing unit configured to store the data having the predetermined format; a transfer unit configured to transfer the data to a designated destination; a judgment unit configured to judge whether the data can be transferred to the designated destination; and an executing unit configured to instruct the image reading apparatus to execute a process for reading the original and for converting the image data to store the data in the storing unit regardless of whether the judgment unit judges that the data can be transmitted, and to instruct the image reading apparatus to transfer the data after the judgment unit judges that the data can be transmitted.

An image processing system includes a first flip-flop bank and a second flip-flop bank, and a control system configured to control JPEG processing of image data. The control system is further configured to, during a first period, use one of the first or second flip-flop banks as a write bank and the other of the first or second flip-flop banks as a read bank and, during a second period, alternate the use of the first and second flip-flop banks as the write bank and the read bank. Further, the control system is configured to, after alternating the use, initialize the read bank to zero.

An image processing apparatus and a control method is provided. The apparatus and method provides that, when a print job to be re-executed is stored, deletes authentication information required for an authentication function in a printing system from among print attributes included in the print job, and then stores the print job in the printing system.
