Abstract

Claims (39)

1 . A face image generation device comprising:

processing circuitry configured to

acquire a first face image to which makeup corresponding to a first pattern has been applied by a user;

extract features of the makeup of the user on the basis of the first face image and first standard data relating to features of standard makeup corresponding to the first pattern;

generate a second face image to which makeup corresponding to a second pattern different from the first pattern has been applied by reflecting the features of the makeup of the user extracted by the feature extracting unit in second standard data relating to features of standard makeup corresponding to the second pattern; and

present the second face image generated by the second face image generating unit to the user,

wherein the first standard data includes information relating to a distribution set in advance for the features of the standard makeup corresponding to the first pattern,

wherein the second standard data includes information relating to a distribution set in advance for the features of the standard makeup corresponding to the second pattern,

wherein the first standard data and the second standard data include information relating to a distribution of features of makeup with reference to a face of a standard size set in advance,

wherein the processing circuitry is further configured to:

generate a first converted face image of the standard size by converting the first face image using a conversion rate according to the first face image,

extract the features of the makeup of the user by comparing the first converted face image with the first standard data,

generate a second converted face image of the standard size by reflecting the features of the makeup of the user in the second standard data, and

generate the second face image of a size corresponding to the first face image by performing reverse conversion of the second converted face image using the conversion rate,

wherein the information relating to the distribution of the features of the makeup included in the first standard data and the second standard data includes an average and a dispersion of a parameter relating to makeup of one or more makeup target portions set in advance,

wherein the processing circuitry, for each of the makeup target portions, is configured to extract a deviation degree representing a degree of deviation of the first converted face image from the first standard data as the feature of the makeup of the user on the basis of a value of the parameter in the first converted face image and an average and a dispersion of the parameter in the first standard data, and

wherein the processing circuitry, for each of the makeup target portions, is configured to calculate a correction value on the basis of the deviation degree and the dispersion of the parameter in the second standard data and determine the value of the parameter in the second converted face image by correcting the average of the parameter in the second standard data using the correction value.

2 . The face image generation device according to claim 1 ,

wherein the processing circuitry is configured to

acquire a plurality of first face images corresponding to the first pattern,

extract the features of the makeup of the user for each of the first face images,

generate a plurality of second face images corresponding to the plurality of first face images on the basis of the features of the makeup of the user for each of the extracted first face images, and

present the plurality of second face images generated by the second face image generating unit to the user.

3 . The face image generation device according to claim 1 ,

wherein the processing circuitry is configured to

acquire a plurality of first face images corresponding to the first pattern, and

extract the features of the makeup of the user on the basis of weights according to use frequencies of the first face images.

4 . The face image generation device according to claim 1 , wherein the processing circuitry is configured to

accept, from the user, a correction of the makeup for the second face image presented to the user; store, in a memory, correction information relating to correction that has been accepted; and

generate the second face image further on the basis of the correction information in a case in which the correction information is stored in the memory.

5 . The face image generation device according to claim 1 , wherein the processing circuitry is configured to generate the first standard data and the second standard data,

wherein the first face image and the second face image are face images applied to an avatar of the user in a virtual space shared among a plurality of users, and

wherein the processing circuitry is configured to:

generate the avatar corresponding to each of a plurality of face images to which makeup in the real world has been applied; and

generate the first standard data and the second standard data on the basis of the features of the makeup of a plurality of the generated avatars.

6 . The face image generation device according to claim 1 , wherein the processing circuitry is configured to generate the first standard data and the second standard data,

wherein the first face image and the second face image are face images applied to an avatar of the user in a virtual space shared among a plurality of users, and

wherein the processing circuitry is configured to generate the first standard data and the second standard data on the basis of features of makeup of a plurality of avatars generated by a plurality of users in the virtual space.

7 . The face image generation device according to claim 6 , wherein the processing circuitry is configured to update the first standard data and the second standard data on the basis of the makeup of the plurality of avatars generated by the plurality of users within a predetermined period for each predetermined period.
