JP4304484B2 - Desktop holder for mobile phone with TV phone function - Google Patents

Description

  The present invention relates to a desktop holder used for a mobile phone with a TV phone function, and more particularly to a desktop holder for a mobile phone that provides a stable TV phone function to a user and a call partner when the mobile phone is mounted.

  At present, mobile phones with a TV phone function are widely used, and not only are they carrying around and using the TV phone function, but the situation of using the TV phone function by placing the mobile phone on a desk is increasing.

  For example, it is also used for negotiations with customers in business situations. When a mobile phone with a TV phone function is used on a desk, the camera position of the TV phone camera is set every time the mobile phone is placed on the desk in order to stabilize the position of the camera. The position is adjusted.

  For personal (private) use, even if the direction of the TV phone camera changes each time, the impression that the other party receives does not differ greatly, but for business use, the background What is projected by the TV phone camera is important, such as what is projected, whether the size of the image is appropriate, and whether the impression changes depending on the brightness and direction of illumination.

  When using the TV phone function, even if the direction of the TV phone camera is adjusted to the position of the face and the direction of illumination is optimally adjusted, the mobile phone is always carried and used again by placing it on the desk. In this case, the direction of the TV phone camera and the illumination direction must be reset.

  When a mobile phone is used on a desk in a quiet office, the speaker volume and microphone sensitivity are changed due to differences in speaker volume and microphone sensitivity from those used on the street.

  When using the TV phone function on an office desk, the microphone often does not want to transmit the surrounding sound to the other party. Therefore, since the directional microphone is used, the microphone direction is adjusted simultaneously with the microphone sensitivity adjustment. ing.

  When using a TV phone on a desk, the mobile phone cannot be kept stable due to slight movements such as opening / closing the drawer or using a writing instrument. Is the current situation.

Further, a related art of a holding device for holding a mobile phone with a TV phone function on a table is described in, for example, Japanese Patent Application Laid-Open No. 2002-176568 (Patent Document 1). The holding device described in Patent Document 1 performs posture control, which is adjustment of the orientation and direction of a camera-equipped mobile phone, with a dial tone signal or a signal from a remote controller while the camera-equipped mobile phone is mounted. It is configured to be able to.
