ABSTRACT:
Disclosed is an image processing apparatus such as a digital copying machine. The image processing apparatus has an image input unit for reading an image of an original, a compression unit for compressing the read image data, a temporary storage unit for temporarily storing the compressed image data, an accumulation unit for accumulating the image data stored in the temporary storage unit, a control unit for measuring the amount of the compressed data and for controlling the start of the process of reading next image data in accordance with a result of the measurement, an expansion unit for reading out image data which have been read out from the compression unit or the accumulation unit and stored in the temporary storage unit, and for expanding the readout image data, and an image output unit for forming an image on the basis of the expanded image data. The amount of compressed data of each of the pages of job 1 is measured, and, in accordance with the result, the process of reading the original of job 2 is performed during the copying process of second and subsequent copy sets of job 1.
