Abstract
A method for correcting magnification in a photographic device is disclosed in this present invention. The point of this invention is that the magnification ratio of a photographic device is saved into a nonvolatile memory and read out for correcting the magnification in the photographic device, so that the image with correct dimension can be output from the photographic device. Therefore, this invention can provide a more efficient method for correcting magnification in a photographic device, and the quality of the image captured by the photographic device can be improved thereby.
Claims17
A method for correcting magnification, comprising:
- obtaining a magnification ratio in a photographic device;
- saving the magnification ratio into a nonvolatile memory;
- and
- reading the magnification ratio from the nonvolatile memory for correcting magnification.
A method for correcting magnification, comprising:
- utilizing a photographic device for capturing a image from a chart;
- obtaining a magnification ratio by calculating a ratio between a first distance within said chart and a secondary distance within said image, wherein said secondary distance is corresponding to said first distance;
- saving said magnification ratio into a nonvolatile memory;
- and
- reading the magnification ratio from said non-volatile memory for correcting magnification.
A method for correcting magnification, comprising:
- utilizing a photographic device for capturing a image from a chart, wherein said chart comprises a first distance and said image comprises a secondary distance corresponding to said first distance;
- calculating a deviation between said first distance and said secondary distance to obtain a magnification ratio;
- saving said magnification ratio into a nonvolatile memory;
- and
- reading said magnification ratio from said non-volatile memory for correcting magnification.
A method for correcting magnification in a scanner, comprising:
- capturing a image from a chart, wherein said chart comprises a first distance and said image comprises a secondary distance corresponding to said first distance;
- utilizing a program to calculate a deviation between said first distance and said secondary distance for obtaining a magnification ratio of the scanner;
- saving said magnification ratio into a nonvolatile memory;
- and
- reading said magnification ratio from said non-volatile memory for correcting magnification.
