摘　　要：针对OPEN-EXR图像的研究大多致力于提高图像的显示质量,而忽略了OPEN-EXR作为一种高动态范围图像（HDR）对显示设备的考虑而提出的一种基于OPEN-EXR图像的JPEG无损压缩。针对JPEG图像的占用内存小,适用设备广的两大特点,完成了OPEN-EXR图像与JPEG图像的无损转化,实现了在小于原图像大小的同时具有一定的图像质量。实验结果表明,该算法在综合考虑图像的显示质量和显示设备的基础上利用图像处理和计算机技术实现数字图像内容的改变,解决了OPEN-EXR图像存储空间大,对显示设备要求高的需求。Most of the research aimed at the open-exr image is to improve the display quality of the image.Instead of the OPEN-EXR as a high dynamic range image（HDR）,a JPEG lossless compression based on OPEN-EXR image is proposed.For the two big characteristics of small memory and wide application equipment,this algorithm completed the OPEN-EXR images and JPEG image lossless transformation,achieved a certain image quality in less than the size of the original image.The experimental results show that the algorithm in consideration of the image display quality and equipment on the basis of the use of image processing and computer technology to realize the change of the content of digital image,solve these problems which OPEN-EXR image storage space is so large,high requirements of display device.
