  • Patent number: 8260344
    Abstract: In a mobile phone device 1 including a three-axial direction vibration sensor 16 for detecting the walking of a user carrying the mobile phone device 1 and counting the number of walking steps, when an incoming call is received, vibrations due to a notification operation by a vibrator 14 or a speaker 15 are transmitted to the three-axial direction vibration sensor 16. As a result, the three-axial direction vibration sensor 16 inevitably detects unintended vibrations in addition to vibrations from walking, causing the number of walking steps to be miscounted. To prevent this and perform the accurate detection of walking, in the present invention, the detection of walking is performed without using, among vibrations in three directions detected by the three-axial direction vibration sensor 16, vibrations in the same direction as the direction of vibrations caused by a notification operation by the vibrator 14 or the speaker 15.

  • Publication number: 20050099528
    Abstract: A mobile terminal device with a camera is provided which can secure emitted light brightness of a camera light unit and save power consumption of the device. During photographing, when the driving power of the camera light unit is increased, driving power for an illumination unit is decreased so that the increase of the total power consumption of the camera light unit and illumination unit can be minimized. In addition, the camera lamp unit and illumination unit are driven by respective driving circuits that share a power supply unit.
