Abstract
An image information acquiring system obtains a group of relative values to describe the image. A pixel value of each pixel in the image is acquired. Ratios between the pixel value of each pixel and a pixel value of each other pixel which is adjacent to the pixel are obtained for obtaining the group of relative values. The group of relative values is used for comparing two images or reproducing another image.
Claims4
An image information acquiring system comprising:
- a processing unit;
- a storage unit connected to the processing unit and storing a plurality of programs to be executed by the processing unit, wherein the storage unit comprises:
- a reading module to acquire a pixel value of each pixel in an image;
- a converting module to calculate a relative value of each pixel comprising ratios between the pixel value of the each pixel and the pixel values of adjacent pixels centering around the each pixel, and to obtain a group of relative values for all pixels in the image;
- and
- a storing module to store the group of relative values;
- wherein the pixel value of each pixel comprises an R value, a G value, and a B value, each ratio between the pixel value of the each pixel and the pixel values of adjacent pixels centering around the each pixel comprises a ratio between the R value of the each pixel and the R value of each of the adjacent pixels, a ratio between the G value of the each pixel and the G value of each of the adjacent pixels, and a ratio between the B value of the each pixel and the B value of each of the adjacent pixels;
- the group of relative values comprises the ratios between the pixel value of the each pixel and the pixel values of the adjacent pixels centering around the each pixel, the ratios are arranged in series according to orientations of the adjacent pixels relative to the pixel;
- wherein upon the condition that there is no pixel at an orientation of the pixel, the relative value at the orientation is marked as a character.

An image reproducing system comprising:
- a processing unit;
- a storage unit connected to the processing unit and storing a plurality of programs to be executed by the processing unit, wherein the storage unit comprises:
- a reading module to acquire a first pixel value of each pixel in an image respectively;
- a converting module to calculate a relative value of each pixel comprising ratios between the first pixel value of the each pixel and the first pixel values of adjacent pixels centering around the each pixel, and to obtain a group of relative values corresponding to the image;
- a storing module to store the group of relative values;
- a reconverting module to give each pixel a second pixel value according to the group of relative values;
- and
- a reproducing module to produce another image according to the second pixel values;
- wherein the group of each of relative values comprises the ratios between the first pixel value of the each pixel and the first pixel values of the adjacent pixels centering around the each pixel, the ratios are arranged in series according to orientations of the adjacent pixels relative to the pixel;
- wherein upon the condition that there is no pixel at an orientation of the pixel, the relative value at the orientation is marked as a character.
