An X-ray telescope (XRT) on board HINODE satellite observes the Sun in X-rays with high special resolution (1arcsec 730km on solar the disk). This telescope has 9 X-ray filters with different temperature responses. Using these filters, the XRT can detect the coronal plasma with a wide temperature range from less than 1MK to more than 10MK. Moreover, based on observations with more than 2 filters, we can estimate the coronal temperature. In this paper, we use the filter ratio method for coronal temperature diagnostics. Using this method, we can easily estimate the averaged temperature of the coronal plasma along the line-of-sight. This method has been used frequently in the past, but the high quality XRT data give us temperature maps with unprecedented accuracy and resolution. The XRT usually takes the full Sun images with 2 kinds of filters 4 times a day. Using this data and filter ratio method, we can obtain full Sun temperature maps with high special resolution. In our analysis, we can derive reliable temperatures not only in active regions but also in quiet regions and coronal holes. This map can be created with the data set of one synoptic observation. This means that we can obtain 4 maps a day. The result is a full Sun temperature movie that gives us an unprecedented view of the time evolution of solar temperature. In this meeting, we will show the full Sun temperature movie and our coronal temperature analysis results.
