Multifunction peripheral capable of executing image processings in parallel, method of controlling same, and storage medium

A method of controlling a multifunction peripheral including a reading controller having a reading section that reads an image of a sheet of a document to generate image data, an image processor configured to execute image processing on image data, and a transfer unit configured to transfer image data from the reading controller to the image processor via a data bus, the method comprising:

• performing first determination for determining whether or not the image processing and another predetermined image processing are executed in parallel;
• performing second determination for determining whether or not settings associated with the image processing are predetermined settings;
• performing third determination for determining whether or not settings associated with the other predetermined image processing are other predetermined settings;
• and
• setting, in a case where it is determined by the first determination that the image processing and the other predetermined image processing are not executed in parallel, a transfer rate of image data to be transferred by the transfer unit to a first transfer rate, and, in a case where it is determined by the first determination that the image processing and the other predetermined image processing are executed in parallel, selecting one transfer rate out of a plurality of different transfer rates lower than the first transfer rate based on a result determined by the second determination and a result determined by the third determination and setting the transfer rate of image data to be transferred by the transfer unit to the selected transfer rate.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method of controlling a multifunction peripheral including a reading controller having a reading section that reads an image of a sheet of a document to generate image data, an image processor configured to execute image processing on image data, and a transfer unit configured to transfer image data from the reading controller to the image processor via a data bus,

• wherein the method comprises:
• performing first determination for determining whether or not the image processing and another predetermined image processing are executed in parallel;
• performing second determination for determining whether or not settings associated with the image processing are predetermined settings;
• performing third determination for determining whether or not settings associated with the other predetermined image processing are other predetermined settings;
• and
• setting, in a case where it is determined by the first determination that the image processing and the other predetermined image processing are not executed in parallel, a transfer rate of image data to be transferred by the transfer unit to a first transfer rate, and, in a case where it is determined by the first determination that the image processing and the other predetermined image processing are executed in parallel, selecting one transfer rate out of a plurality of different transfer rates lower than the first transfer rate based on a result determined by the second determination and a result determined by the third determination and setting the transfer rate of image data to be transferred by the transfer unit to the selected transfer rate.
