An electronic device and a method of measuring an amount of user physical activity by an electronic device are provided. The method includes establishing short range communication among a plurality of electronic devices, determining one of the plurality of electronic devices as a primary device, communicating state information of remaining electronic devices to the primary device, activating a sensor on a device having a highest priority among the plurality of electronic devices according to the state information, recording physical activity information according to physical activity sensed by the sensor, communicating the physical activity information to the primary device, calculating an amount of physical activity according to the communicated physical activity information, and synchronizing the amount of physical activity among the plurality of electronic devices.

Method and device for measuring amount of user physical activity

An image filtering method and apparatus that filter a block of a plane area by using a pseudo-random filter are provided, whereby artifacts generated in image encoding and decoding procedures are removed, the method including: determining a similarity between pixel values of a the first block; and generating a second block by selectively applying a pseudo-random filter on the first block according to a result of based on the determining the determined similarity.

Image filtering method using pseudo-random number filter and apparatus thereof

A method of inter prediction encoding of an image, the method including: searching for a first reference block in a reference picture by using a current block, and estimating a first motion vector in a first pel unit in regards to the first reference block; estimating a second motion vector by using pixels included in a pre-encoded area adjacent to the current block, and pixels adjacent to the first reference block, and determining a second reference block based on the second motion vector; and encoding the current block based on the first motion vector and the second reference block.
