Zusammenfassung:Provided are an electronic device for providing an avatar based on a user face and an operating method thereof. The electronic device according to an embodiment of the present disclosure may obtain a plurality of raw textures by matching a 3-dimensional shape related to the user face to a 2-dimensional plane, perform tone-matching of smoothing each of skin tones of the plurality of raw textures on the basis of an average of skin tones of a pre-plurality of raw textures, obtain a plurality of texture segments by splitting at least one of the tone-matched plurality of raw textures according to feature areas in a face, obtain a combined texture by combining a plurality of texture segments selected by a user input from among the obtained plurality of texture segments, and obtain an avatar indicating the user face in the 3-dimensional shape on the basis of the combined texture. L'invention concerne un dispositif électronique pour fournir un avatar sur la base d'un visage d'utilisateur et son procédé de fonctionnement. Le dispositif électronique selon un mode de réalisation de la présente divulgation peut obtenir une pluralité de textures brutes par mise en correspondance d'une forme tridimensionnelle associée au visage d'utilisateur avec un plan bidimensionnel, effectuer une mise en correspondance de tonalités de lissage de chacune des tonalités de peau de la pluralité de textures brutes sur la base d'une moyenne de tonalités de peau d'une prépluralité de textures brutes, obtenir une pluralité de segments de texture par division d'au moins une texture de la pluralité à tonalités mise en correspondance de textures brutes conformément aux zones de caractéristiques dans un visage, obtenir une texture combinée par combinaison d'une pluralité de segments de texture sélectionnés par une entrée d'utilisateur parmi la pluralité obtenue de segments de texture, et obtenir un avatar indiquant le visage de l'utilisateur dans la forme tridimensionnelle sur la base de la texture combinée. 사용자 얼굴에 기초한 아바타를 제공하는 전자 장치 및 그 동작 방법을 제공한다. 본 개시의 일 실시 예에 따른 전자 장치는 사용자 얼굴에 관한 3차원 형상을 2차원 평면 상에 대응시킴으로써 복수의 로우(raw) 텍스쳐들을 획득하고, 기 복수의 로우 텍스쳐들의 피부 톤(tone)의 평균에 기초하여 복수의 로우 텍스쳐들의 피부 톤을 각각 평활화하는 톤매칭(tone-matching)을 수행하고, 톤매칭된 복수의 로우 텍스쳐들 중 적어도 하나를 얼굴 내 특징 영역 별로 분할하여 복수의 텍스쳐 세그먼트들을 획득하고, 획득된 복수의 텍스쳐 세그먼트들 중 사용자 입력에 의해 선택된 복수의 텍스쳐 세그먼트들을 조합함으로써 조합 텍스쳐를 획득하고, 조합 텍스쳐에 기초하여 사용자 얼굴을 3차원 형상으로 나타내는 아바타를 획득할 수 있다.
