RAW视频文件格式研究

摘要

RAW格式以其对图像原始采集,无损压缩和高可塑性的特点被广泛应用于工业技术领域的数码相机与摄像机.但由于RAW图像格式无法被计算机直接显示,所以必须将其转换为常用的图像格式BMP或JPG.其中RAW视频本质上是由RAW图像序列组成,因此本文针对RAW图像格式进行研究.为了解决以上问题,本文将使用MATLAB编程实现把RAW文件格式的图像转换为常见的BMP、JPG等位图格式,并实现缩放等图像的基本操作.经过对RAW、BMP和JPG格式的分析研究,最终实现了对RAW图像格式的转换,并加入了图形界面和图像的简单操作.%RAW format is widely used in industrial technology digital cameras and cameras with its original image acquisition, lossless compression and high plasticity characteristics. However, since the RAW image format can''t be displayed directly by the computer, it must be converted to a common image format BMP or JPG. Which RAW video is essentially composed of RAW image sequence, so this paper for RAW image format to study. In order to solve the above problems, this paper will use MATLAB programming to achieve the RAW file format images into a common BMP, JPG bitmap format, and to achieve the basic operation of rotation scaling and other images. After the analysis of RAW, BMP and JPG format, the realization of the RAW image format conversion, and joined the graphical interface and image of the simple operation.
