<p>PURPOSE:To obtain objective screens with comparatively easy control even if the screens of more than three are displayed in prescribed priority by outputting picture data in accordance with priority written in a control register. CONSTITUTION:If first to fourth priority circuits 10-40 are provided and a code showing that the first screen has first priority is outputted from the control register 70, for example, when there are four screens, for example, the first priority circuit 10 is designated. Picture data in the first screen is read from an element, into which picture data of the first screen in the first priority circuit 10 is written, is transmitted to a picture display/processing circuit and displayed on a television screen. When a code that the second screen has second priority is outputted from the control register 70, the second priority circuit 20 is designated and picture data in the second screen of the second priority circuit 20 is displayed on the television screen. Thus, the first screen of first priority is displayed in a front row, and then the screen of second priority is displayed at the backward of the first screen.</p> |
