    • PROBLEM TO BE SOLVED: To uniformize image quality characteristics of a plurality of display terminals highly accurately. SOLUTION: An image quality adjusting device 12 which performs image quality adjustment to image information displayed on a screen of a display terminal 11 has: an analyzing means 22, which acquires chromaticity data, profile data and histogram data from image information obtained by photographing the screen of the display terminal 11 by an imaging means 21 which acquires image information using two kinds of cameras, a spectral camera and an RGB camera, and analyzes image quality characteristics consisting of still picture characteristics and moving picture characteristics; and an image quality adjusting means 23, which generates a look-up table (LUT) for adjusting the image quality of the display terminal 11 corresponding to previously set image quality adjustment contents, based on image quality evaluation data on the display terminal 11, which is obtained from the analyzing means 22, and then adjusts image quality of the display terminal 11 by updating the image quality information previously set in the display terminal 11, by using the generated look-up table.
