Description
Ａ／Ｄ変換回路１には、アナログの入力映像信号が入力されてデジタルデータに変換され、映像信号データとして出力される。画像変換装置２では、水平解像度変換回路４および垂直解像度変換回路５によって、映像信号データの水平解像度および垂直解像度が液晶パネル３の解像度に順次変換される。液晶パネル３では、解像度変換された映像信号データに基づいた画像が画面全体に拡大されて表示される。 An analog input video signal is input to the A / D conversion circuit 1 , converted into digital data, and output as video signal data. In the image conversion device 2, the horizontal resolution conversion circuit 4 and the vertical resolution conversion circuit 5 sequentially convert the horizontal resolution and the vertical resolution of the video signal data to the resolution of the liquid crystal panel 3. On the liquid crystal panel 3, an image based on the resolution-converted video signal data is enlarged and displayed on the entire screen.
なお、本実施形態において、画像変換装置２は、水平解像度変換回路４および垂直解像度変換回路５を有しているが、入力される映像信号がテレビ放送用の信号である場合には、水平解像度変換回路４が省略できることは言うまでもない。
また、水平解像度変換回路４の構成および動作については、垂直解像度変換回路５の説明から明らかであるので、詳しい説明を省略している。
In the present embodiment, the image conversion device 2 has a horizontal resolution conversion circuit 4 and a vertical resolution conversion circuit 5, but when the input video signal is a signal for television broadcasting, the horizontal resolution Needless to say, the conversion circuit 4 can be omitted.
Further, since the configuration and operation of the horizontal resolution conversion circuit 4 are clear from the description of the vertical resolution conversion circuit 5, detailed description is omitted.
