Claims (1)
信号及び画面上のワイプ波形のサイズを連続して
変化させるサイズ制御信号によつて制御されるワ
イプ波形発生器において、前記ワイプ波形発生器
が出力するワイプ波形信号の画面上での形状毎の
外接サイズの変化をデータとして記憶すると共に
前記波形選択信号及び前記サイズ制御信号を受け
前記波形選択信号に対応するデータに応じて前記
サイズ制御信号を補正して前記ワイプ波形発生器
へ出力するサイズ補正ＲＯＭ部を備えることを特
徴とするワイプ波形発生器。 A wipe waveform generator controlled by a waveform selection signal that selects the shape of the wipe waveform on the screen and a size control signal that continuously changes the size of the wipe waveform on the screen, the wipe waveform generator outputs A change in the circumscribed size of each shape on the screen of the wipe waveform signal is stored as data, and upon receiving the waveform selection signal and the size control signal, the size control signal is corrected according to data corresponding to the waveform selection signal. A wipe waveform generator comprising: a size correction ROM section that outputs the data to the wipe waveform generator.
