Patent Images
1. 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, said method comprising:
- deriving an integral magnification for each of all the pixels of the input image data per direction in which the number of the pixels of the input image data is increased/decreased; and
copying a pixel value of each of said pixels based on said integral magnification to obtain said output image data, wherein said integral magnifications of all the pixels are derived and stored in a magnification table in advance, and the pixel value of each pixel is copied as many times as represented by the corresponding integral magnification stored in said magnification table to obtain said output image data.

12. 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, said method comprising:
-
deriving an integral magnification for each of all the pixels of the input image data per direction in which the number of the pixels of the input image data is increased/decreased; and
copying a pixel value of each of said pixels based on said integral magnification to obtain said output image data, wherein said integral magnification for each pixel is derived based on a predetermined regular relationship between positions of the pixels in the input image data and integral magnifications of the corresponding pixels, said predetermined regular relationship is stored in a magnification table, and the pixel value of each pixel is copied based on said magnification table and a given arithmetic expression to obtain said output image data. - View Dependent Claims (13, 14)

15. The 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, said method comprising:
-
deriving an integral magnification for each of all the pixels of the input image data per direction in which the number of the pixels of the input image data is increased/decreased; and
copying a pixel value of each of said pixels based on said integral magnification to obtain said output image data, wherein said desired magnification is divided into an integral part magnification and a decimal part magnification, and when multiplication of the decimal part magnification causes no occurrence of raising to unit, the integral part magnification is set as said integral magnification, while, when the multiplication of the decimal part magnification causes an occurrence of raising to unit, said integral magnification is derived by increasing the integral part magnification. - View Dependent Claims (16, 17, 18, 19, 20)
