By analyzing according to the four divisions of the GB component, FIG.
The data of the color histogram shown in FIG. 4 is created, colors are selected as color candidates in descending order of frequency value from the created data of the color histogram, and the color palette 3 shown in FIG. create. Further, the display unit 30 displays the color palette 3 to the operator. This allows the operator to prepare for expressing the color scheme representing the operator's emotion applied to the sample image 1 in the uncolored image 2 without selecting an emotional phrase as in the related art. , From a limited number of emotional phrases,
The operator's emotion can be accurately reflected on the uncolored image 2 without selecting a phrase representing the operator's emotion.

Further, in the color arrangement support apparatus of the first embodiment, since various sample images 1 can be inputted from the input unit 10 at any time, it corresponds to the same emotion depending on the individual or the time or place. A subtle difference in the color arrangement can be accurately reflected on the uncolored image 2.

The processing section 20 has the maximum frequency value among the 64 color groups included in the color histogram.
Instead of selecting a kind of color group and creating a color palette 3 in which the twelve kinds of color groups are arranged as color candidates, the color palette 3
May be created. That is, the processing unit 20 includes, for example,
A color pallet 3 in which at least all of the color groups having a frequency of 1 or more are arranged as color candidates as they are may be created.

In addition, instead of classifying the pixels constituting the sample image 1 into 64 types of color groups, the processing unit 20 uses a number of colors far exceeding the number required for coloring the uncolored image 2. In order to avoid candidates from being included in the color palette 3, for example, the number of color groups corresponding to the number of regions included in the uncolored image 2 or a larger number of color groups, for example, the color group shown in FIG. In color scheme 2, there are 5 groups,
Alternatively, it is desirable to classify into five or more color groups.

<Embodiment 2> A color arrangement support apparatus of Embodiment 2 will be described.
