Abstract:
1. An image processing apparatus comprising: a first image processing unit, including a first transfer buffer, to process image data read by an image reading unit; a main memory to store the image data transferred from the first transfer buffer; a second image processing unit, including a second transfer buffer, to process the image data read from the main memory and output processed data to an image output unit; a monitoring unit to monitor a data amount in the first transfer buffer, and a data amount in the second transfer buffer; and an arbitration unit to arbitrate data transfer, so that when the data amount in the first transfer buffer becomes not less than a predetermined first threshold value, a number of times of data transfer from the first transfer buffer to the main memory is increased, and when the data amount in the second transfer buffer becomes not more than a predetermined second threshold value, a number of times of data transfer from the main memory to the second transfer buffer is increased.
