    摘要： A brushless direct current (BLDC) motor includes a rotor having a cylindrical permanent magnet to which a shaft is centrally coupled, and supported to rotate on the shaft. An annular stator surrounds the rotor and includes a plurality of teeth and a wound coil to generate an electromagnetic field. The permanent magnet includes a stress reducing portion, which is provided at opposite end portions thereof, and which has a shape having a mass or a volume which is smaller than a mass or a volume per unit length in an axial direction of a portion of the permanent magnet other than the opposite end portions, to reduce centrifugal stress caused by spinning of the rotor.

    摘要： According to an embodiment of the disclosure, an electronic device may include a communication interface, a dynamic vision sensor (DVS) to generate bit data for each of a plurality of image frames, based on change in illuminance, a processor electrically connected with the communication interface and the DVS, and a memory electrically connected with the processor. The memory may store instructions, and the instructions may cause the processor to filter out at least a partial frame of the plurality of image frames, based on a ratio of the number of a bit value, which is included in the bit data and corresponds to each pixel, to the number of total pixels constituting each of the plurality of image frames, and recognize a shape of a surrounding object of the electronic device, based on another frame of the plurality of image frames. Moreover, various embodiment found through the disclosure are possible.

    摘要： An electronic device is provided. The electronic device includes communication circuitry configured to communicate with an external electronic device, a processor operatively connected with the communication circuitry, and a memory operatively connected with the processor. The memory may store instructions which, when executed, cause the processor to control the electronic device to: obtain environment information associated with a video playback environment of the external electronic device, decode a high dynamic range (HDR) video, perform color conversion of the decoded HDR video based on the environment information, encode the color-converted video into a standard dynamic range (SDR) format, and transmit the encoded video to the external electronic device via the communication circuitry.
