Video phone call method having function of adjusting resolution quality and video phone call apparatus supporting the same

A video phone call apparatus for adjusting resolution quality, the apparatus comprising:

• a Radio Frequency (RF) communication unit configured to transmit a video phone call connection request message and to receive a video phone call connection accept message in response to the video phone call connection request message so as to form a communication channel for connection of video phone call;
• a camera configured to collect an image signal for the video phone call;
• an audio processor configured to collect an audio signal for the video phone call;
• and
• a controller configured to create a control signal for controlling the image signal and the audio signal, to create video phone call data including the image signal, the audio signal, and the control signal, and to add a collected video frame to the video phone call data to generate integral video phone call data having an additional video frame when the video phone call data has a packet size less than a preset value according to a data transfer protocol, wherein the controller comprises a network electric field information collecting unit configured to collect network electric field information of a communication network for the video phone call, and to add the additional video frame and the network electric field information in a stuffing data region when a packet size of the video phone call data is less than the data transfer protocol determined for the video phone call by a predetermined value.
