參數(shù)資料

Sub-screen Size

The vertical and horizontal directions are controlled independently.

1. Vertical size

1/3 to (3) scan lines are compressed to a single scan line

1/4 to (4) scan lines are compressed to a single scan line

2. Horizontal size

1/3 to A/D clock: D/A clock = 1:3

1/6 to A/D clock: D/A clock = 1:6

The data required for 1/6 reduction is one half that for 1/3 reduction.

Aspect correction function

The horizontal direction size is adjusted by changing the VCO oscillator frequency (system clock).

This can be adjusted from –30% to +30%.

However, care is required when using this function. See the Application Manual for details.

2E mode

If 2E mode is used when 1/3 size is selected, the horizontal direction is expanded by a factor of two.

This is normally used only for special functions such as split mode.

Number of Sub-screens

Between one and eight sub-screens can be specified (when 1 Mb of VRAM is used).

Split mode

Refer to the Application Manual for details on using these modes.

No. 4872-7/19
