摘要： An electronic device is provided. The electronic device includes at least one processor and a memory. The memory may store at least one instruction that, when executed by the at least one processor, enables the electronic device to obtain a first image frame and a second image frame. The memory may store at least one instruction that, when executed by the at least one processor, enables the electronic device to identify a first interpolation-applied object and a first interpolation non-applied object among objects included in the first image frame and identify a second interpolation-applied object and a second interpolation non-applied object among objects included in the second image frame. The memory may store at least one instruction that, when executed by the at least one processor, enables the electronic device to provide an interpolation image frame including a result of interpolation on the first interpolation-applied object and the second interpolation-applied object and the first interpolation non-applied object or the second interpolation non-applied object.

摘要： An electronic device is provided. The electronic device includes a wireless communication circuit configured to transmit or receive at least one radio frequency (RF) signal, at least one processor, and a memory. The memory includes instructions that, when executed, enable the at least one processor to generate a first random address of the electronic device, transmit a first advertising packet including the first random address, receive a scan request corresponding to the first advertising packet from an external electronic device, generate a first encrypted random address resulting from encrypting the first random address and a second encrypted random address resulting from encrypting the second random address corresponding to reception of the scan request, transmit a scan response including the first encrypted random address and the second encrypted random address to the external electronic device, and transmit a second advertising packet including the second random address.

摘要： An electronic device may comprise: a housing comprising a first plate which faces a first direction and a second plate which faces a second direction opposite to the first direction, the housing having a space formed between the first plate and the second plate; a side member which surrounds at least a part of the space; a display which is disposed inside the housing and is exposed through the first plate; a printed circuit board which is disposed inside the housing and is disposed between the display and the second plate; and a communication module which is disposed inside the housing and is coupled to the printed circuit board. The side member may comprise: a first conductive member which extends around the space; a second conductive member which extends around the space so as to be in parallel with the first conductive member, wherein the first conductive member is spaced from the second conductive member, the second conductive member is more adjacent to the second plate than the first conductive member, and the second conductive member has at least a part which is electrically connected to the communication module; and a first insulating member which extends around the space so as to be in parallel with the first conductive member and is disposed between the first conductive member and the second conductive member. In addition, other various embodiments are possible.

摘要： An electronic device configured to establish a first Bluetooth low energy (BLE) connection with an external electronic device, measure a distance between the external electronic device and the electronic device based on a first distance measurement scheme, identify whether the distance is within a set range between a first distance and a second distance. Based on a determination that the distance is within the set range, measure a distance between the external electronic device and the electronic device based on a second distance measurement scheme and establish a second BLE connection with the external electronic device. Based on a determination that the distance measured based on the second distance measurement scheme is shorter than the second distance, measure a distance between the electronic device and the external electronic device based on an ultra-wide band (UWB) technology.

摘要： Provided is an image encoding method including generating a first picture reconstructed by using a residual picture and a predicted picture; generating a second picture by applying a first artifact reduction filter to the first picture; determining a picture having a smaller bit-rate distortion cost from among the first and second pictures by comparing a first bit-rate distortion cost of the first picture with a second bit-rate distortion cost of the second picture; generating a third picture by applying an in-loop filter to the determined picture; generating a fourth picture by applying a second artifact reduction filter to the third picture; determining a picture having smaller distortion from among the third and fourth pictures by comparing first distortion of the third picture with second distortion of the fourth picture; and generating, via a processor, a bitstream including information about whether the second artifact reduction filter is applied.
