Scalable
DU series provides the scalable mode that can read out defined area of the screen.
In the scalable mode, camera reads out only necessary area at the normal speed and reads out other area
at high speed. The frame rate can be faster when the vertical height size is small. However, the frame rate
cannot be faster only when the horizontal width size is small.
Only single rectangle is selectable. Concave or convex shape is not selectable.
- Window size: {A + 4 × m (H)} × {B + 2 × n (V)}
A, B = minimum unit size
m, n = integer
The window size is equal or less than maximum image size.
- Start address: {4 x i (H)} x {2 x j (V)}
i, j = integer
The window size is equal or less than maximum image size.
