摘要：
Image processing technique (IPT) is a computational technique which is a simple, wide and great for many purposes. In this paper, we used IPT to obtain plasma source such as sun and sunspot temperatures. Sun image was taken by a telescope and DSLR camera and imported to MATLAB software. Using the IPT, we cropped two areas and evaluated their RGB values, using a code which was written according to Python software. We computed wavelengths and then by substituting wavelengths in Wien's law, we obtained sun's surface and sunspot temperature's. The temperature errors for surface and sunspot were 0.57% and 13% respectively. (C) 2016 The Author. Published by Elsevier B.V.
