Problems solved by technology

For this reason, people have proposed a variety of data compression methods to reduce the amount of data. Better compression software can compress files to a few tenths of the original data amount. However, various compression methods affect the quality of image restoration to varying degrees. quality, the code-saken phenomenon occurs
At present, in libraries, archives and other units, the following two methods are generally used to store official documents, blueprints and other materials. One is to manually enter text files, and the other is to scan to form image data files. The former method saves space. However, only the text content is recorded, and the original appearance of the data cannot be preserved. The disadvantage of the latter method is that the file data volume is large, the processing and transmission efficiency is low, and the equipment requirements are high.

Embodiment Construction

[0013] The specific implementation of the method of the present invention will be further described below.

[0014] First, use special equipment, such as a scanner, to digitize the image. Then, the processing and storage of the image data includes counting all the specific colors contained in the original image according to the image data and converting each specific color image to a monochrome image. Steps in which the data is stored in the form.

[0015] Pixels with the same color value in the image usually have continuity within a certain interval. Therefore, in the process of counting specific color data, this feature can be used to improve operating efficiency and reduce noise, and the numbers are taken sequentially within the statistical format adjacent pixels, compare the color values ​​of the first and last pixels, if they are equal, use the color value as a specific color and judge whether the color value of the specific color has been counted, if not, add the color v...

Abstract

The image datamation storming includes image data processing and data storing process, in which the special colors of the original image are counted and each specific color part in the image are stored in monochromic image data. To color image, especially image with relatively simple color composition, the said method has less file number formed and can ensure the quality of the restored image.

Description

technical field [0001] The present invention relates to image processing, in particular to a data storage method for images. Background technique [0002] At present, the basic method used for digital storage of image data is to divide the entire format into pixels arranged in a row, and store the color of each pixel in the form of numerical value. Usually, image data is stored in the form of color data files or monochrome data files according to the original image characteristics and image processing requirements. When stored in the form of color data files, the color is converted into a certain proportion of basic colors. For example, red, green, and blue are represented by values ​​from 0 to 255, and the color value of a pixel is composed of the values ​​​​of the three basic colors. Record 2563 or 16777216 colors. Using this method to record and store images can better guarantee the quality of restoration, but due to the huge amount of data, the r...
