Two representative digital cameras were selected and their characteristics data before and after making ICC profile were collected. The performance difference of the cameras was analyzed through the data fitting. The results were validated by subjective evaluation through establishment of six criteria. The experimental results showed that image color difference of image with color management is less than the image without color management; by comparison of the effect difference between the image before and after making ICC profile, it was concluded that making ICC profile in digital camera is necessary. Manuscript representation of different camera under different shooting conditions was summarized and a feasible evaluation scheme was proposed for digital camera related workers and user.
