ABSTRACT:
In an image processing apparatus, an image reading unit reads an original for each line in a main scanning direction and outputs image data of the original. A memory unit stores the image data, the memory unit having a storage capacity equal to at least one line in the main scanning direction. A control unit generates a write address and a read address of the storage unit so that the image data is written into a storage area specified by the write address and is read from a storage area specified by the read address. An output unit drives an output image from the image data read from the memory unit. A data erasing unit controls either the read address or the write address of the memory unit generated by the control unit so that unnecessary image data which is not required to be output is erased before the unnecessary image data is written into or read from the memory unit.
