<p>PURPOSE:To attain the frame displaying switching in a short time even when a processing capability is in the low environment by overlapping, displaying and outputting the blanked frame data to clear the displaying element of an old frame in the displaying and the displaying data of a new frame. CONSTITUTION:Frame data to line-decompose a displaying element 14 of an old frame 10 during the displaying and the displaying element 14 being blanked are, for example, prepared in a program buffer. When the old frame 10 is displayed and switched to a new frame 12, a displaying element 16 line-decomposes so as to become maximum 1 data per line, further, the overlapping data to overlap the new frame 12 are prepared, and by outputting and displaying this, the switching and displaying are executed from the old frame 10 to the new frame 12. Consequently, when the displaying element of the old frame is cleared, simultaneously, it can be rewritten to the displaying element of the new frame. Thus, even when the processing capability is in the low environment, the frame can be displayed and switched in a short time.</p> |
