Abstract: A wireless communications device establishes effective video calls, even if the user is not aware of the appropriate imaging conditions. An image resizing system and method for a wireless communication device is disclosed. Video data is captured and modified based on an operating condition. The modified video data is then transmitted through a communication channel. In this manner, processing time and processing load of a wireless communication device are reduced, while allowing a smooth communication during video calls.

Abstract: A vehicle terminal apparatus has a connection monitoring unit for monitoring a disconnection of a communication link between a wireless communication device and a portable terminal, considering an abnormal disconnection of the communication link as a link loss, considering a disconnection of the communication link by a disconnection process by the wireless communication device as a first disconnection, and considering a disconnection of the communication link by a disconnection process, by the portable terminal as a second disconnection; and a connection condition determination unit for determining a wireless connection condition of the wireless communication device based on a disconnection reason that accounts for a reason for disconnection and a pre-disconnection call condition that is a call condition of the portable terminal immediately before the disconnection when the disconnection of the communication link is detected by the connection monitoring unit.
