Abstract: An electronic device includes an image sensor configured to receive light that is incident on the electronic device through a lens and generate image data, a gyroscope configured to generate rotation motion data of the electronic device, and an image stabilizer configured to generate translation motion data of the electronic device based on the image data received from the image sensor and to generate a stabilized image by compensating for a motion of the electronic device while capturing the image, such as vibration of a handheld device. The stabilized image is generated based on filtered translation motion data obtained by performing a first filtering operation on the translation motion data and filtered rotation motion data obtained by performing a second filtering operation on the rotation motion data received from the gyroscope.

Abstract: Methods and apparatuses for managing wireless signal information for positioning a mobile terminal are provided. The wireless signal information obtained by measuring a signal characteristic with respect to access points of a target area, is stored in a database. At least one piece of position error information calculated based on the wireless signal information is received from at least one mobile terminal. A positioning reliability is assessed with respect to the target area, based on the at least one piece of position error information. It is determined whether to update the wireless signal information, based on the assessed position reliability.
