Description

Digital Map Color Correction Apparatus {APPARATUS FOR MODIFYING ARRANGEMENT OF COLOR}

The present invention relates to a digital map color matching device, and more particularly, to a digital map color matching device for providing a digital map color matching model based on a user's preferred image.

Color is a visual element that psychologically affects a person's mood, and research on the effect of color on a person has been ongoing for a long time.

Although there are some differences depending on the culture, according to the study of color psychology, a single color has a meaning (meaning) and mood (mode, mood) of each color. And, color combination has an important influence on a person's mood.

In addition, colors make everyone feel different emotions based on personal experiences. And, rather than triggering a specific emotion with just one color, it was studied that a series of emotions exist according to the color combination.

Therefore, it can be assumed that colors induce specific emotions in people through their relationship with the surrounding colors, and this is similarly applied when we appreciate paintings.

In addition to quantitative factors such as area ratio, positional relationship, and shape, multiple factors such as individual differences, that is, user's personal preference and preference, age, and color vision abnormality, also have a large influence, but It is difficult to provide a single color matching model that can satisfy all needs.
