Abstract: A device includes an image sensor configured to generate a first signal corresponding to an image having a first resolution in a first mode, a second signal corresponding to an image having a second resolution higher than the first resolution in a second mode. The image sensor is configured to generate frame information regarding a resolution, the first mode and the second mode respectively determined based on a mode signal. The device further includes a channel allocator configured to allocate the first signal and the second signal to different channels, of a plurality of channels, based on the frame information; and an image signal processor (ISP) comprising the plurality of channels, a first channel configured to process the first signal and a second channel configured to process the second signal. The ISP is configured to post-process image data processed by the plurality of channels.

Abstract: The present disclosure relates to a communication scheme and system for converging a 5th generation (5G) communication system for supporting a data rate higher than that of a 4th generation (4G) system with an internet of things (IoT) technology. The present disclosure is applicable to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, and security and safety-related services) based on the 5G communication technology and the IoT-related technology. A proposed method for a base station to transmit information controlling configuration of an uplink (UL) secondary component carrier (SCC) corresponding to a secondary cell in a wireless communication system supporting carrier aggregation (CA) includes identifying first information associated with an uplink electric field of a primary cell, transmitting measurement configuration information associated with the secondary cell to a terminal, receiving a measurement report message associated with the secondary cell from the terminal, identifying second information associated with a downlink electric field of the secondary cell based on the measurement report message, and transmitting the information controlling configuration of the UL SCC of the secondary cell to the terminal based on at least one of the first information or the second information.

Abstract: The present disclosure relates to an electronic device for acquiring images by using a plurality of cameras and a method for processing images by using the same. According to an embodiment of the present disclosure, the electronic device may comprise a first camera, a second camera including a lens assembly and a driving unit capable of changing an optic axis of the lens assembly, and a processor. The processor can receive a photographing signal for an external object; acquire a first image of the external object by using the first camera, acquire a second image of the external object by setting the lens assembly of the second camera to a first direction; acquire a third image of the external object by setting the lens assembly of the second camera to a second direction; and generate an image of the external object by synthesizing at least one part of the first image with at least one part of the second image, and synthesizing at least one other part of the first image with at least one part of the third image. Further, other various embodiments can be implemented according to the present disclosure.
