Abstract An electronic device according to an embodiment of the present document may comprise an image sensor including a plurality of unit pixels, and at least one processor electrically connected to the image sensor. Each unit pixel may include PDs, i.e., TL, TR, BL, and BR, which are disposed under a micro lens and have a 2x2 arrangement. The at least one processor may: acquire a first image frame from the image sensor; determine a driving mode of the image sensor on the basis of the first image frame; and according to the driving mode of the image sensor, perform H-direction AF by using TL, BL, or TL+BL AF data and TR, BR, or TR+BR AF data or perform V-direction AF by using TL, TR, or TL+TR AF data and BL, BR, or BL+BR AF data. Various other embodiments identified through the specification are also possible. Un dispositif électronique selon un mode de réalisation du présent document peut comprendre un capteur d'image comportant une pluralité de pixels unitaires, et au moins un processeur connecté électriquement au capteur d'image. Chaque pixel unitaire peut comporter des PD, c'est-à-dire TL, TR, BL, et BR, qui sont disposés sous une microlentille et ont un agencement 2x2. Le ou les processeurs peuvent : acquérir une première trame d'image à partir du capteur d'image ; déterminer un mode de commande du capteur d'image sur la base de la première trame d'image ; et selon le mode de commande du capteur d'image, effectuer une mise au point automatique de direction H à l'aide des données de mise au point automatique TL, BL ou TL + BL et des données de mise au point automatique TR, BR ou TR + BR ou effectuer une mise au point automatique de direction V à l'aide des données de mise au point automatique TL, TR ou TL + TR et des données de mise au point automatique BL, BR, ou BL + BR. Divers autres modes de réalisation identifiés par la description sont également possibles. 본 문서의 일 실시 예에 따른 전자 장치는, 복수의 단위 픽셀들을 포함하는 이미지 센서, 및 상기 이미지 센서와 전기적으로 연결된 적어도 하나의 프로세서를 포함할 수 있다. 각각의 단위 픽셀은 마이크로 렌즈의 아래에 배치되고 2x2 배열을 가지는 PD들, 즉 TL, TR, BL, 및 BR을 포함할 수 있다. 상기 적어도 하나의 프로세서는, 상기 이미지 센서로부터 제1 이미지 프레임을 획득하고, 상기 제1 이미지 프레임을 기반으로 상기 이미지 센서의 구동 모드를 결정하고, 상기 이미지 센서의 구동 모드에 따라 TL, BL, 또는 TL+BL AF 데이터와 TR, BR, 또는 TR+BR AF 데이터를 이용하여 H 방향의 AF를 수행하거나, TL, TR, 또는 TL+TR AF 데이터와 BL, BR, 또는 BL+BR AF 데이터를 이용하여 V 방향의 AF를 수행할 수 있다. 이 외에도 명세서를 통해 파악되는 다양한 실시 예가 가능하다.
