目前计算图像色差的典型方法不能准确反应真实的观察效果。介绍了基于色相角算法的图像评价方法，从色相角度出发，对图像中的各个像素进行不同程度的加权，从而控制每个像素对整幅图像的影响效果。通过实验与传统色差计算方法进行了对比，验证了该方法的有效性和普遍性。

Current typical calculation methods of image color difference can not correctly reflect the true observing effect. An image evaluation method based on hue angle algorithm was introduced, which weighted every pixel on different scale in the image and then calculating the color difference of whole image. Experiment was carried out for comparison with traditional color difference calculation methods. The results showed that the method is effective and universal. This paper studied an image evaluation method which weighting every pixel on different scale in the image and then calculating the whole image color difference. This method control the result based on the color hue and the result is tested effectively and acceptably by experiment.
