## Abstract

An application control device according to an embodiment of the present invention has an acquisition unit that acquires image data of a skin; a division unit that divides the image data into a plurality of segments each smaller than or equal to 200 μm; and a calculation unit that calculates, from a value of one or a plurality of segments of the image data, an application amount of a cosmetic material to be applied to each portion of the skin.

## Claims

### Claim 1

An application control device comprising:
an acquisition unit that acquires image data of a skin;
a division unit that divides the image data into a plurality of segments each smaller than or equal to 200 μm or; and
a calculation unit that calculates, from a value of one or a plurality of segments of the image data, an application amount of a cosmetic material to be applied to each portion of the skin.

### Claim 2 (depends on 1)

The application control device according to claim 1, wherein a distance between the centers of adjacent segments out of the plurality of segments is larger than or equal to 20 μm and smaller than or equal to 150 μm.

### Claim 3 (depends on 1)

The application control device according to claim 1, wherein the calculation unit calculates the application amount of the cosmetic material to be applied to each portion of the skin from a value of the plurality of segments of the image data by using an impulse response function that represents a light scattering between each portion of the skin corresponding to each of the plurality of segments.

### Claim 4 (depends on 3)

The application control device according to claim 3, wherein when one of the plurality of segments is used as a target segment, the impulse response function represents:
a ratio at which a light entering a target portion of the skin corresponding to the target segment is emitted out of a surface of the target portion of the skin, or
a ratio at which a light entering a non-target portion of the skin corresponding to a non-target segment other than the target segment is emitted out of a surface of the target portion of the skin.

### Claim 5 (depends on 3)

The application control device according to claim 3,
wherein the calculation unit calculates the application amount of the cosmetic material based on a light reflection scattering model; and
wherein a light obtained at the target portion of the skin corresponding to the target segment when one of the plurality of segments is used as a target segment in the reflection scattering model at least includes:
in the light emitted to a surface of a target portion of the skin corresponding to the target segment, a component which is reflected from the surface of a target portion of the skin without inward transmission from the surface;
in the light emitted to the surface of the target portion of the skin corresponding to the target segment, a component which is reflected after inward transmission from the surface of a target portion of the skin and then emitted out of the surface of the target portion of the skin; and
in the light emitted to the surface of the non-target portion of the skin corresponding to the non-target segment other than the target segment, a component which is reflected after inward transmission from the surface of a non-target portion of the skin and then emitted out of the surface of the target portion of the skin.

### Claim 6 (depends on 1)

The application control device according to claim 1, wherein the image data includes an illuminance value.

### Claim 7 (depends on 1)

The application control device according to claim 1 further comprising:
a storage unit that stores the image data; and
an application head that forms an application film of the cosmetic material by ejecting the cosmetic material to the skin based on the application amount of the cosmetic material calculated by the calculation unit,
wherein the acquisition unit acquires the image data from the storage unit.

### Claim 8

An application control method comprising steps of:
acquiring image data of a skin;
dividing the image data into a plurality of segments each smaller than or equal to 200 μm; and
calculating, from a value of one or a plurality of segments of the image data, an application amount of a cosmetic material to be applied to each portion of the skin.

### Claim 9

A program that causes a computer to execute:
an acquisition process that acquires image data of a skin;
a division process that divides the image data into a plurality of segments each smaller than or equal to 200 μm; and
a calculation process that calculates, from a value of one or a plurality of segments of the image data, an application amount of a cosmetic material to be applied to each portion of the skin.

### Claim 10 (depends on 9)

A computer readable storage medium that stores the program according to claim 9.
