Image processing apparatus, method of controlling image processing apparatus, and storage medium

A method of controlling an image processing apparatus comprising:

• a reading unit configured to read a document and generate image data;
• an image processing unit configured to perform image processing;
• and
• a printing unit, the method comprising:
• controlling a transfer rate for transferring the image data from the reading unit to the image processing unit;
• and
• determining whether the image processing on the image data is to be executed in parallel with other image processing different from the image processing,
• wherein, in a case where the determining determines that the image processing on the image data is not to be executed in parallel with the other image processing different from the image processing and the printing unit starts printing an image of the document after reading of an image of a first page of the document is completed, the controlling sets the transfer rate to a predetermined transfer rate, and
• wherein, in a case where the determining determines that the image processing on the image data is not to be executed in parallel with the other image processing different from the image processing and the printing unit starts printing the image of the document without waiting for the reading of the image of the first page of the document to be completed, the controlling sets the transfer rate to a transfer rate lower than the predetermined transfer rate.

A non-transitory computer-readable storage medium that stores a program for causing a computer to execute a method of controlling an image processing apparatus comprising:

• a reading unit configured to read a document and generate image data;
• an image processing unit configured to perform image processing;
• and
• a printing unit, the method comprising:
• controlling a transfer rate for transferring the image data from the reading unit to the image processing unit;
• and
• determining whether the image processing on the image data is to be executed in parallel with other image processing different from the image processing,
• wherein, in a case where the determining determines that the image processing on the image data is not to be executed in parallel with the other image processing different from the image processing and the printing unit starts printing an image of the document after reading of an image of a first page of the document is completed, the controlling sets the transfer rate to a predetermined transfer rate, and
• wherein, in a case where the determining determines that the image processing on the image data is not to be executed in parallel with the other image processing different from the image processing and the printing unit starts printing the image of the document without waiting for the reading of the image of the first page of the document to be completed, the controlling sets the transfer rate to a transfer rate lower than the predetermined transfer rate.
