Patent ID: 7817195

Claim:
An apparatus for automatic conversion to a digital zoom mode in a wireless communication terminal, comprising: a display unit to display video data; a camera unit to capture the video data; a key pad having a digital zoom key; a video processing unit to process the video data from the camera unit, to determine a current resolution mode of the video data, and to execute a digital zoom function; a control unit to determine whether the current resolution mode of the video data supports the digital zoom function, and if the current resolution mode is too high to support the digital zoom function, to convert the current resolution mode to a highest resolution mode among resolution modes supporting the digital zoom function upon executing the digital zoom function, where the highest resolution mode supporting the digital zoom function corresponds to a lower resolution than the current resolution mode; and a memory unit to store the video data at the highest resolution mode supporting the digital zoom function, wherein the video processing unit scales the video data received from the camera unit to the highest resolution mode among resolution modes supporting the digital zoom function if the control unit determines that the current resolution mode does not support the digital zoom function.
