【課題を解決するための手段】
この課題を解決するため、例えば本発明の通信端末は以下の構成を備える。すなわち、
音声および画像データの通信を行う通信端末であって、前記通信端末の筐体に配置される第１の撮像素子と、前記通信端末の筐体に配置される第２の撮像素子と、前記第１および第２の撮像素子からの出力信号を制御処理する制御処理ユニットとを有することを特徴とする。 [0010]
[Means for solving the problem]
In order to solve this problem, for example, a communication terminal of the present invention has the following configuration:
A communication terminal for communicating voice and image data, characterized in that it has a first imaging element disposed in the housing of the communication terminal, a second imaging element disposed in the housing of the communication terminal, and a control processing unit that controls and processes output signals from the first and second imaging elements.

第１のデジタル映像信号はＣＰＵ２３０で、色分離、白バランス、ガンマ補正、アパーチャ補正などの基本処理と、ビデオフォン装置２００の操作キー２１２で設定された、画像サイズ、画質調整、位置調整などの付加処理を行う。さらに、設定された圧縮方法と圧縮パラメータによって画像圧縮を行い第１の画像圧縮データを得る。同様に、第２のデジタル映像信号はＣＰＵ２３０で、色分離、白バランス、ガンマ補正、アパーチャ補正などの基本処理と、ビデオフォン装置２００の操作キー２１２で設定された画像サイズ、画質調整、位置調整などの付加処理を行う。さらに、設定された圧縮方法と圧縮パラメータによって画像圧縮を行い、第２の画像圧縮データを得る。音声データは、ビデオフォン装置２００の操作キー２１２で設定された音質調整などの付加を行い、設定された圧縮方法と圧縮パラメータによって音声圧縮データを得る。第１の画像圧縮データ、第２の画像圧縮データと音声圧縮データは、無線伝送データとして再構築され、制御データと共に送信データとしてＰＨＳインターフェース２１８に送られ、通話先に送られる。また、必要に応じて（例えば操作キー３０６中の所定キーの操作に応じて）外部入出力端子２１７にも送られる。さらに、送信画像データ確認用として、必要（操作キー３０６中の所定のキー操作）に応じて、画像圧縮データを伸長して、表示ドライバ２１３を通して、表示器２１４に表示される。 The first digital video signal is subjected to basic processing such as color separation, white balance, gamma correction, and aperture correction, as well as additional processing such as image size, image quality adjustment, and position adjustment, which are set using the operation keys 212 of the videophone device 200, by the CPU 230. Image compression is then performed using the set compression method and compression parameters to obtain first compressed image data. Similarly, the second digital video signal is subjected to basic processing such as color separation, white balance, gamma correction, and aperture correction, as well as additional processing such as image size, image quality adjustment, and position adjustment, which are set using the operation keys 212 of the videophone device 200. Image compression is then performed using the set compression method and compression parameters to obtain second compressed image data. The audio data is subjected to additional processing such as sound quality adjustment, which is set using the operation keys 212 of the videophone device 200, as well as audio compression using the set compression method and compression parameters. The first compressed image data, second compressed image data, and audio compressed data are reconstructed as wireless transmission data and sent to the PHS interface 218 as transmission data together with control data, and then transmitted to the call destination. If necessary (for example, in response to the operation of a predetermined key among the operation keys 306), the data is also sent to the external input/output terminal 217. Furthermore, for confirmation of the transmitted image data, if necessary (in response to the operation of a predetermined key among the operation keys 306), the compressed image data is expanded and displayed on the display 214 via the display driver 213.
