Described in the first to third embodiments above is the configuration that the user sets a desired color tone through the color information setting screen displayed on the image display unit 11 by means of the position of the indicator 41, the hue value, or the hue difference value. That is, in the first to third embodiments described above, the user who can change the color information through the color information setting screen is limited to a person who has some expertise in colors.

A facility equipment management apparatus according to a fifth embodiment differs from those in the first to fourth embodiments in that the user can determine through the information setting screen a tint the user wants to use while seeing a colored sample image of the screen that is actually displayed. Except for this point, the fifth embodiment is the same as the first to fourth embodiments. For this reason, the fifth embodiment will be described with reference to FIGS. 1 to 5 also. In the case of the fifth embodiment, it is also possible for the user who does not understand the meaning of technical terms such as the hue value and the hue difference value to make the setting easily through the color information setting screen.

FIG. 15 is a schematic diagram showing a color information setting screen of an image display unit 11 of the facility equipment management apparatus according to the fifth embodiment. The color information setting screen includes a sample image 59 showing a color tone of a present image, an Add button 52, a Subtract button 53, an OK button 54, and a Cancel button 55. The sample image 59 presents a sample of a tint of an image displayed in accordance with a present hue value to the user and helps the user understand the tint intuitively.
