Abstract
A data conversion method and a data conversion device convert a large cubic three-dimensional image data to a plurality of pieces of small cubic one-dimensional image data, or convert a plurality of pieces of small cubic one-dimensional image data to a large cubic three-dimensional image data. The data conversion method includes the following steps, marking a three-dimensional index on three-dimensional image data; converting the three-dimensional index to a writing sequence index; inputting the three-dimensional image data to a buffer memory in sequence according to the writing sequence index; computing a reading sequence index according to the writing sequence index; outputting data blocks from the buffer memory in sequence according to the reading sequence index. Through the method and the device, use of the memory is reduced, and time for conversion is lowered.
