Zusammenfassung:	The present invention relates to an electronic device and, more specifically, to a device and a method for improving an image resolution in a camera system including a lens that causes distortion. An electronic device according to an embodiment of the present invention comprises: an image sensor that generates pixel data based on light received through a lens that causes distortion which compresses a captured image in a first direction; and an image signal processor that performs re-mosaic processing on the pixel data for correcting the distortion occurring in the first direction and to generate re-mosaiced pixel data. 본 발명은 전자 장치에 관한 것으로, 좀 더 상세하게는 왜곡을 발생시키는 렌즈를 갖는 카메라 시스템에서 이미지 해상도를 개선하는 장치 및 방법에 관한 것이다. 본 발명의 실시 예에 따른 전자 장치는 촬영되는 이미지를 제 1 방향으로 압축시키는 왜곡을 발생시키는 렌즈를 통해 수신된 빛에 기반하여 픽셀 데이터를 생성하는 이미지 센서 및 상기 픽셀 데이터에 대해 상기 제 1 방향으로 발생한 왜곡을 보정하기 위한 리모자이크 처리(remosaic processing)를 수행하여 리모자이크된 픽셀 데이터를 생성하는 이미지 신호 프로세서를 포함한다.
