• •• • Scalable mode
This camera has the scalable mode that can read out defined area of the screen. The horizontal and
vertical minimum unit sizes, at 32 × 24 pixels, both represent a 32-part split of total screen horizontal
and vertical sizes. A read out area can be designed by start address (i, j). However, specify an address
by every 4 pixels. Only continuous square units can be selected, concave or convex shape cannot be
selected.
Window of 32 × 24 pixels per unit
: 32*m(H) × 24*n(V) (m/n = An integer: 1,2,3,4…32)
Selectable the video of 1024 × 768 (maximum)
Up to 1 window
Start address : 4*i(H) × 4*j(V)
(i = integer: 0,1,2,3,…248)
( j = integer: 0, 1, 2,…186)
A window is in the screen
In the scalable mode, this camera reads out only the necessary portions at the standard speed while it
scans through other unnecessary portions at high speed, so the trigger interval can be shorter if the
vertical cutout width is small. However, the trigger interval cannot be short in the horizontal
direction even if the cutout width is small due to the operation mechanism of the CCD sensor.
Notice
White lines may occur in the upper portions of the screen when strong light exists in a wide area during
the scalable mode. This is not a malfunction. If white lines occur, adjust the amount of incident light
using the lens.
