Abstract: There is provided a system (1) including a ball (10), which incorporates a first sensor that functions as at least a triaxial acceleration sensor, a triaxial gyro sensor, and a triaxial geomagnetic sensor and also includes a first communication unit (16) that wirelessly transmits sensor data detected by the first sensor; and a mobile terminal (20) including a second communication unit (21) that is paired with the first communication unit. The mobile terminal includes: a unit (61) that acquires external information indicating an environment in which the paired ball moves independently; and a unit (63) that generates ball movement data (55) of the paired ball in which the sensor data of the paired ball obtained via the first communication unit and the second communication unit is associated with the external information.

Abstract: A technique for drawing or managing multimedia data by desired groups. In a built-in memory of a cellular phone terminal, thirteen picked-up image data are stored. In tag information of each of the thirteen picked-up image data, information on date and time is recorded when an image of the data is picked up. When a user specifies the range of image pickup date and time, eight picked-up image data that match the specified range of image pickup date and time are selected and synthetic image data is generated from these eight picked-up image data.
