Abstract
(EN) According to various embodiments, an electronic device may comprise a communication module for communicating with an external electronic device, a display device configured with at least one display module, a memory, and a processor operatively connected to the communication module, the display device, and the memory. The processor may control the display device to at least partially change a state of the at least one display module; obtain, by using a camera of the external electronic device, an image corresponding to the at least one display module, the state of which has been changed; identify first interval information between the at least one display module, on the basis of the obtained image; compare the identified first interval information with second interval information between at least one pixel included in the at least one display module; determine a position error value of the at least one display according to a result of the comparison; determine a compensation value to be reflected in the at least one pixel according to the result of comparison; and partially control the brightness of the at least one pixel on the basis of the determined compensation value. Various other embodiments may be possible.
(FR) Selon divers modes de réalisation, un dispositif électronique peut comprendre un module de communication servant à communiquer avec un dispositif électronique externe, un dispositif d'affichage pourvu d'au moins un module d'affichage, une mémoire et un processeur fonctionnellement connecté au module de communication, au dispositif d'affichage et à la mémoire. Le processeur peut commander le dispositif d'affichage pour modifier au moins partiellement un état du ou des modules d'affichage ; obtenir, à l'aide d'une caméra du dispositif électronique externe, une image correspondant audit module d'affichage dont l'état a été modifié ; identifier des premières informations d'intervalle entre le ou les modules d'affichage sur la base de l'image obtenue ; comparer les premières informations d'intervalle identifiées à des secondes informations d'intervalle entre au moins un pixel inclus dans le ou les modules d'affichage ; déterminer une valeur d'erreur de position du ou des dispositifs d'affichage en fonction d'un résultat de la comparaison ; déterminer une valeur de compensation devant être reflétée dans le ou les pixels en fonction du résultat de la comparaison ; et régler la luminosité du ou des pixels de façon partielle sur la base de la valeur de compensation déterminée. Divers autres modes de réalisation sont possibles.
(KO) 다양한 실시예에 따르면, 전자 장치에 있어서, 외부 전자 장치와 통신하기 위한 통신 모듈, 적어도 하나의 디스플레이 모듈로 구성된 디스플레이 장치, 메모리, 및 상기 통신 모듈, 상기 디스플레이 장치, 및 상기 메모리와 작동적으로 연결된 프로세서를 포함할 수 있다. 상기 프로세서는, 상기 디스플레이 장치를 제어하여, 상기 적어도 하나의 디스플레이 모듈을 적어도 부분적으로 상태를 변화시키고, 상기 외부 전자 장치의 카메라를 이용하여, 상기 상태가 변화된 적어도 하나의 디스플레이 모듈에 대응되는 이미지를 획득하고, 상기 획득된 이미지를 기반으로, 상기 적어도 하나의 디스플레이 모듈 간의 제 1 간격 정보를 확인하고, 상기 확인된 제 1 간격 정보 및 상기 적어도 하나의 디스플레이 모듈에 포함된 적어도 하나의 픽셀 간의 제 2 간격 정보를 비교하고, 상기 비교 결과에 따른 상기 적어도 하나의 디스플레이의 위치 오차값을 결정하고, 상기 비교 결과에 따른 상기 적어도 하나의 픽셀에 반영하기 위한 보상값을 결정하고, 상기 결정된 보상값을 기반으로 상기 적어도 하나의 픽셀의 밝기를 적어도 부분적으로 제어할 수 있다. 그 밖에 다양한 실시예들이 가능할 수 있다.
