- the present invention relates to a color arrangement changing device that changes the color arrangement of a screen so that the balance of the entire screen becomes appropriate, and more particularly to a color arrangement changing device that takes into account human visual characteristics.
- the type and number of information displayed on the screen vary depending on the situation. For example, in the case of a monitoring business system screen, the number of warnings and caution information displayed on the screen is greater when an abnormality occurs than during normal operation. This increases the proportion of the area of the color assigned to the warning or caution information on the screen. Thus, when the type and number of information displayed on the screen change, the balance of the conspicuousness of each color on the entire screen may be lost. For example, it is assumed that the system designer considers the warning information to be highly important information for the user and assigns red, which is a conspicuous color, as a single unit on the above-described monitoring business system screen. However, for example, if a large amount of warning information is displayed on the screen when an abnormality occurs, the proportion of red on the screen increases, and the way red stands out when viewed on the entire screen drops.
- the color scheme determined when designing the screen cannot be changed in many cases after the product is completed. Although customization by the user may be allowed even after the product is completed, the user needs to perform a change operation one by one.
