Method and apparatus for converting data

A method of converting data, the method comprising:

• receiving range information of input data used to calculate output data;
• calculating size information of an input buffer using the range information of the input data;
• loading the input data using the size information of the input buffer;
• and
• calculating the output data using the loaded input data.

An apparatus for converting data comprising:

• an information receiver to receive size information of an output buffer and receive range information of input data used to calculate output data corresponding to each of the points within the output buffer;
• an input buffer size information calculator, which uses at least one processor, to calculate size information of the input buffer using the size information of the output buffer and the range information of the input data;
• and
• an output data calculator to load the input data using the size information of the input buffer and calculate the output data using the loaded input data.
