Abstract: Disclosed herein is a method of operating an electronic device having a camera. The electronic device includes a camera, a display unit, a sensor unit configured to detect an external event value, an image processor configured to process data received through the camera into a preview image, and a main processor. The main processor is configured to switch from a preview mode to a ready mode when the external event value is detected by the sensor unit, wherein the preview mode comprises activation of the camera, the image processor to display the preview image on the display unit, and the ready mode comprises deactivation of the camera and the image processor and display of a ready mode image on the display unit.

Abstract: An operating method of a wireless communication device includes: receiving a reference signal transmitted from a second wireless device; calculating a reference noise value based on the reference signal; calculating, by the processor, a noise threshold value based on the reference noise value; receiving a first data signal transmitted from the second wireless device; calculating a data noise value based on the first data signal; comparing, by the processor, the data noise value with the noise threshold value; determining whether interference occurs in a target symbol based on a result of the comparison; adjusting the noise threshold value based on the data noise value when it is determined that the interference has occurred in the target symbol; and receiving a second data signal transmitted from the second wireless device, and using the adjusted noise threshold value in processing the second data signal.
