On the other hand, if the window 11b to be displayed by the processing task 4 is currently displayed in a size of 50% of the screen on which the processing task 4 originally draws,
This screen is reduced to one half, and it is considered that the contents of the screen do not change significantly even if the screen is updated at the original update cycle. Therefore, regarding the drawing request signal, the original 2
It is assumed that the update is performed at a double cycle of 1 second, and that other drawing request signals are not sent to the display means 6. Similarly, in the processing task 5, if the window 11c is 33% of the original size, the drawing request signal updates the screen at three times the original cycle.

In the second embodiment, the drawing update cycle is calculated by dividing the update cycle by the reduced size of the screen of the CRT device 11. For example, a weighting variable is added to each screen in advance, It is also possible to change the update cycle from the weighting variable and the size of the window.
