Furthermore, the intensity change interval (d2) of the gray scale characteristic and the white balance characteristic measurement signal (T2) is narrower than the intensity change interval (di) of the sfl number (T1) of the video signal conversion circuit characteristic test. The human eye has a color or color difference higher than saturation, and is more sensitive to distinguish the change in brightness of white or the change in chromaticity of white. The change in the chromaticity of white means the change in the temperature of the white color. Focusing on the visual characteristics of such humans, this embodiment sets the gray scale characteristics and the white balance characteristics of the target device 5 to be more detailed than the color management characteristics. Therefore, the stipulation mode also slightly adjusts the color management of the target device to make the human visual sense. Therefore, the present embodiment can efficiently adjust the image of the target device 50. In order to measure the color reproducibility of the target device 50, it is necessary to measure rGb, 22 1357267, that is, three colors. Therefore, when the number of measurement steps of the gray scale change of one color is N1, the number of steps required for measuring the color reproducibility characteristic is the third power of Νι. Assuming that the first intensity interval d 1 = the second intensity interval d2, even if the number N1 of measurement steps of the gray scale change of one color is the same as the number N2 of measurement steps of the gray scale change of the brightness (= 256), the color reproduction is measured. The number of steps required for sexual characteristics is 256 cubics = about 16.77 million. For example, when the measurement time per step is changed to 1 second, the measurement of the color reproducibility characteristic takes about 194 days, which is impractical. However, the image quality adjusting device 1 of the present embodiment is set to the first intensity interval dl > the second intensity interval d2 ^, that is, the number of measurement steps N1 of the gray scale change of one color is less than the gray scale of the intensity The number of measured steps is N2 = 256 (N1 < N2). Therefore, for example, when the number of steps of the gray scale change of one color is N1 = 17, the number of steps required for measuring the color reproducibility characteristic is the third of 7 and about 1.3 hours. In other words, the image quality adjusting device 10 of the present embodiment sets the number of measurement steps of the gray scale change of one color to less than the number N2 of measurement steps of the gray scale change of the brightness, thereby making the measurement time of the color reproducibility characteristic Realistic value. Therefore, the quality adjusting device 1 can adjust the color reproducibility of the target device 50 with an accuracy that does not cause an obstacle. The above embodiment can also be modified as follows. The video measurement signal used in S5-1 of Fig. 7 is not limited to the first test signal T1 having the first ι intensity interval dl. The third intensity interval of the intensity change interval of the video measurement signal is set to be larger than the second intensity interval d2, that is, the display analyzer 40 is not limited to a point from the reference device 3 〇 and the target device 23 / / 267 5 individual center In the test _ |, do not 疋 two stimulus values X, Υ, Ζ. The display analyzer 40 obtains the tristimulus values X, γ, and z from the points other than the center of the target device 50 from the reference device 30ifepiA; Kui ^ teaches 0, and obtains the tristimulus values X, Y from a plurality of points. Z is also available. The component signal signal supplied by the signal generator 20 to the reference device 3 and the target device 5 is not limited to the Ypbpr signal, and may also be supplied with the code number. That is, the way in which the output signal of the video signal is 0 is not limited to the BTA S-100R. The "ive~ specification is the brightness-color difference of the so-called HD-SDI specification. The reference slot 30 and the target device 5 are not limited to the liquid crystal display, respectively, and may be an electric display or a projector. That is, the reference device 3A and the target device 50 are respectively adjustable image output devices. The image quality adjusting device 1〇' adjusts the quality of the plurality of target devices 50 to set the characteristics according to the respective target devices 5〇. For example, when a plurality of target devices 5A have a common characteristic, the quality adjusting device 10 can also set the characteristics of the plurality of target devices 50 at a time.
