Abstract
An image processing apparatus divides an address space in which input image data are arranged into a plurality of blocks and can change a block from which reading of the image data in each line is started and a data reading start address in each block, so that an output image to an input image can be processed or corrected freely or deviation of the output image to the input image can be corrected.
Claims10
A method of accessing a cell of a memory device for image processing, comprising:
- comparing a first value to a first partial address;
- changing a second partial address by a prescribed value, if the first value is within a prescribed range of the first partial address;
- and
- accessing the cell of the memory device identified by the first and second partial addresses.

A memory accessing apparatus for image processing, comprising:
- a first register that provides a first value;
- a first counter that provides a first partial address;
- a comparator that compares the first value provided by the first register and the first partial address provided by the first counter, said comparator providing an indication if the first value is within a prescribed range of the first partial address;
- a second counter that provides a second partial address;
- a logic unit that receives the second partial address from the second counter and then changes the second partial address, if the comparator provides the indication that the first value is within the prescribed range of the first partial address;
- and
- a memory comprising a plurality of cells;
- and
- an access device, wherein
- the access device accesses the memory cell identified by the first and second partial addresses.
