- the present invention is not limited to the above-described embodiment.
- the embodiment may be modified as follows. Moreover, you may implement combining the following modifications.
- the density of the makeup object may change according to a predetermined parameter.
- the predetermined parameter includes, for example, the length of the trajectory.
- the drawing unit 104 may decrease the density of the makeup object as the locus becomes longer.
- the predetermined parameter may include pressure.
- the user terminal 10 includes a pressure sensor that measures the pressure applied to the surface of the display 16.
- the drawing unit 104 may increase the density of the makeup object as the pressure measured by the pressure sensor increases.
- the predetermined parameter may include the moving speed of the indicator 20.
- the user terminal 10 or the indicator 20 includes a speed sensor that measures the moving speed of the indicator 20.
- the drawing unit 104 may decrease the density of the makeup object as the moving speed measured by the speed sensor increases.
- the correction unit 106 may perform correction processing as follows.
- FIG. 9 is a diagram for explaining an example of correction processing according to this modification.
- the correction unit 106 extracts densities D3 (an example of the first density) and D4 (an example of the second density) from the reference regions 37 and 38 adjacent to the overlapping portion 36, respectively.
- D3 an example of the first density
- D4 an example of the second density
- the correcting unit 106 corrects the density of the overlapping portion 36 so as to gradually change from the density D3 to the density D4. Thereby, the density difference between the overlapping portion 36 and the reference regions 37 and 38 is reduced.
- Modification 2 when a predetermined condition is satisfied, the correction process may not be performed or the degree of the correction process may be reduced. For example, when the thickness of the makeup object is equal to or less than the threshold value T2, the correction process may not be performed. On the other hand, when the thickness of the makeup object is larger than the threshold value T2, correction processing is performed as in the above-described embodiment. This is because when the makeup object is large in thickness, the density difference between the overlapped portion and the other portion is conspicuous. On the other hand, when the makeup object is small in thickness, it is between the overlapped portion and the other portion. This is because it is difficult to recognize the difference in density.
- Modification 3 In the above-described embodiment, when the overlapping portion at the position corresponding to the change point is large, there is no intention of overlapping the color in the region close to the change point, while the color is overlapped in the region far from the change point. It is thought that there is intention to paint. Accordingly, in this case, for example, correction processing is performed for a predetermined range including the change point in the overlapping portion, while correction processing is not performed for other regions, or the degree of correction processing may be reduced. Good.
- FIG. 10 is a diagram for explaining an example of the correction process according to this modification.
- the correction unit 106 corrects the density of the region 39 in a predetermined range including the point P3 in the overlapping portion 36 as in the above-described embodiment. On the other hand, the correction unit 106 does not perform density correction for the region other than the region 39 in the overlapping portion 36.
- the density of the overlapping portion may be corrected regardless of whether the trajectory has a change point.
- This overlapping portion may include not only the overlapping portion at the position corresponding to the change point but also other overlapping portions.
- the correcting unit 106 may correct the density of all the overlapping portions of the makeup object corresponding to the locus.
- This predetermined area is an area where it is difficult to specify the position accurately using the indicator 20, for example.
- the makeup object may overlap when the indicator 20 contacts an unintended position.
- the density may be corrected for the overlapping portion located in the predetermined area.
- the correcting unit 106 when the frequency or frequency at which the indicator 20 has passed the predetermined area is equal to or greater than the threshold T3, or the time interval at which the indicator 20 has passed the predetermined area is equal to or less than the threshold T4, the correcting unit 106 The density of all overlapping portions of the makeup object corresponding to the locus may be corrected. This is because even when such a condition is satisfied, it is considered that there is no intention of overlapping colors on the overlapping portion.
- a person different from the user may perform an operation of applying makeup on the face image of the user using a terminal different from the user terminal 10.
- the person different from the user is, for example, an instructor such as a professional makeup artist. In this case, the user can see the makeup applied by the instructor and learn the makeup and makeup method that suits him.
- FIG. 11 is a diagram showing an example of the image processing system 1 according to this modification.
- the image processing system 1 includes a user terminal 10 (an example of a second terminal) and another terminal 30 (an example of a first terminal).

- the transmission unit 107 transmits screen data indicating a screen displayed on the display (an example of a display unit) of the terminal 30 to the user terminal 10.
- the user terminal 10 functions as a second display control unit 108 and a correction control unit 109 in addition to the acquisition unit 101 and the correction unit 106 described in the embodiment. These functions are realized by one or more processors 11 executing programs stored in the memory 12.
- the second display control unit 108 causes the display 16 (an example of the second display unit) to display a screen corresponding to the screen data received from the terminal 30. Thereby, screen sharing is performed between the terminal 30 and the user terminal 10.
- the correction control unit 109 controls execution of correction processing by the correction unit 106 according to the screen size of the display 16.
- the user terminal 10 transmits image data indicating the user's face image 61 to the terminal 30 through the communication interface 13.
- the terminal 30 causes the first display control unit 112 to display the face image 61 indicated by the image data received from the user terminal 10 on the display.

At this time, position coordinates indicating the position of the overlapping portion at the position corresponding to the change point may be transmitted together with the screen data.
- User terminal 10 receives screen data from terminal 30 through communication interface 13. Subsequently, the user terminal 10 causes the display 16 to display a screen corresponding to the screen data by the second display control unit 108. When a makeup object having an overlapping portion at a position corresponding to the change point is included on the screen, the user terminal 10 performs a correction process for correcting the density of the overlapping portion by the correction unit 106 before displaying the screen. You may go. This overlapping portion is specified by the position coordinates received from the terminal 30.
- the user terminal 10 may control the execution of the correction process by the correction control unit 109 according to the screen size of the display 16. For example, when the screen size of the display 16 is larger than the threshold value T5, execution of the correction process may be permitted. On the other hand, when the screen size of the display 16 is equal to or smaller than the threshold T5, the execution of the correction process may be prohibited, or the degree of the correction process may be reduced. This is because when the screen size of the display 16 is small, the density difference between the overlapped portion and other portions is not noticeable. Thereby, the processing amount of the image processing system 1 can be reduced.
- the face image 61 on which makeup is applied by the instructor is displayed on the display 16 of the user terminal 10 in real time. Thereby, the user can browse a state where makeup is applied to his / her face image 61 by the instructor.

Abstract
Description
本発明は、ユーザの意図に沿った化粧のシミュレーションを行うことを目的とする。
図1は、本実施形態に係るユーザ端末10の外観の一例を示す図である。ユーザ端末10は、タブレット端末、携帯端末、パーソナルコンピュータ等のコンピュータである。ユーザ端末10は、ユーザにより使用される。ユーザ端末10は、タッチパネルを備え、ユーザの指やスタイラスペン等の指示体20を用いた操作を受け付ける。ユーザ端末10は、指示体20を用いた操作に応じて、ユーザの顔画像を用いた化粧のシミュレーションを行う。
図5は、本実施形態に係る化粧のシミュレーション処理の一例を示すフローチャートである。この処理では、ユーザの顔画像を用いた化粧のシミュレーションが行われる。
本発明は上述した実施形態に限定されない。実施形態は、以下のように変形してもよい。また、以下の変形例を組み合わせて実施してもよい。
上述した実施形態において、所定のパラメータに応じて、化粧オブジェクトの濃度が変化してもよい。この所定のパラメータには、例えば軌跡の長さが含まれる。この場合、描画部104は、軌跡が長くなるほど、化粧オブジェクトの濃度を下げてもよい。
上述した実施形態において、所定の条件を満たす場合には、補正処理を行わず、又は補正処理の程度を下げてもよい。例えば、化粧オブジェクトの太さが閾値T2以下の場合には、補正処理を行わなくてもよい。一方、化粧オブジェクトの太さが閾値T2より大きい場合には、上述した実施形態と同様に補正処理を行う。これは、化粧オブジェクトの太さが大きい場合には、重なり部分と他の部分との間の濃度差が目立つ一方、化粧オブジェクトの太さが小さい場合には、重なり部分と他の部分との間の濃度差を認識し難いためである。
上述した実施形態において、変化点に対応する位置にある重なり部分が大きい場合には、変化点に近い領域については色を重ねて塗る意図はない一方、変化点から遠い領域については色を重ねて塗る意図があるとも考えられる。したがって、この場合には、例えばこの重なり部分において変化点を含む所定の範囲の領域については補正処理を行う一方、それ以外の領域については補正処理を行わず、又は補正処理の程度を下げてもよい。
上述した実施形態において、所定の条件を満たす場合には、軌跡が変化点を有するか否かに関わらず、重なり部分の濃度が補正されてもよい。この重なり部分には、変化点に対応する位置にある重なり部分だけでなく、それ以外の重なり部分が含まれてもよい。
上述した実施形態において、ユーザとは異なる人が、ユーザ端末10とは異なる端末を用いて、ユーザの顔画像に化粧を施す操作を行ってもよい。ユーザとは異なる人とは、例えばプロのメイクアップアーティスト等のインストラクターである。この場合、ユーザは、インストラクターによって施された化粧を見て、自分に似合う化粧や化粧の仕方を学ぶことができる。
上述した実施形態では、指示体20がディスプレイ16の表面に接触することにより、顔画像上の位置が指定されていたが、顔画像上の位置を指定する方法はこれに限定されない。例えば、ユーザ端末10が、ディスプレイ16の表面から法線方向に沿って形成される所定の検出範囲内に位置する指示体20を検出するセンサーを有する場合には、指示体20がディスプレイ16の表面に近接することにより、顔画像上の位置が指定されてもよい。
軌跡の形状又は変化点の位置は、実施形態で説明した例に限定されない。例えば、軌跡は曲線であってもよい。この場合、軌跡における方向の変化量として、曲率が用いられてもよい。この場合、軌跡において閾値以上の曲率を有する点が変化点となってもよい。
ユーザ端末10又は画像処理システム1において行われる処理のステップは、上述した実施形態で説明した例に限定されない。この処理のステップは、矛盾のない限り、入れ替えられてもよい。また、本発明は、ユーザ端末10又は画像処理システム1において行われる処理のステップを備える方法として提供されてもよい。
本発明は、ユーザ端末10又は端末30において実行されるプログラムとして提供されてもよい。このプログラムは、インターネット等のネットワークを介してダウンロードされてもよい。また、これらのプログラムは、磁気記録媒体(磁気テープ、磁気ディスクなど)、光記録媒体(光ディスクなど)、光磁気記録媒体、半導体メモリなどの、コンピュータが読取可能な記録媒体に記録した状態で提供されてもよい。
