Title: Scanning signal generation device
Inventor: OMATA SATOSHI
IPC: G09G1/00
Filed: 1987-10-09
Abstract: PURPOSE:To unify a blanking time of a picture signal of each mode by designating plural kinds of mode, whose frequency of countup pulses is different each other, and selecting the corresponding countup change-over data by mode designation. CONSTITUTION:For instance, when a mode 1 is selected, line buffers 11-1, 11-2 are put on the state 'ON' so that comparators 6-1 and 6-2 compare countup change-over data DH-1-1, DV1-1 with a counter output to determine change-over timing to countup. Here, changing to a mode 2, the countup change-over data are changed to DH1-2 and D1-2. A blanking time can be held constant by setting-up of the data DH1-2 and DV1-2, even when a frequency countup pulse is lowered. In this way, even when scanning speed is lowered, a picture number per unit time can be increased so as to be able to reduce a flicker of the picture.
