<p>PURPOSE:To call an operator's attention by a flickering display and to make a variation of information easily understandable by selecting an optimum decision algorithm of a blink deciding circuit, even in the case of a display image which is hidden due to superiority or inferiority of the degree of priority by a multi-window display and a superposition display. CONSTITUTION:When a display system having a high degree of priority is brought to flickering designation, a flickering operation of its display system is executed, and when a display system having a low degree of priority is brought to flickering designation, its lighting operation is inhibited and the display of the display system having a high degree of priority is maintained. Also, when an A system and a B system are both brought to flickering designation, the flickering display is executed alternately. That is, the display of a B system display memory 14 is divided into a first and a second groups G1, G2, the G1 display sets the degree of priority lower than that of an A system memory 13 and the G2 display sets the degree of priority higher than that of the memory 13. When data of a blink plane 14b in the B system memory 14 is brought to flickering designation in a state that the A system display is flickering at present, a blink deciding circuit 18 is operated by a decision algorithm, and flickering is executed alternately by gate circuits 15, 16.</p> |
