Image data adjusting device and method

摘要

An image data adjusting method for increasing/decreasing the number of pixels of input image data in a given direction with a desired magnification to obtain output image data. The method includes deriving an integral magnification for each of all the pixels of the input image data per direction in which the number of pixels of the input image data is increased/decreased, and copying a pixel value of each of the pixels based on the integral magnification to obtain the output image data.
