Toshiba CS3950DIF manual Scalable mode

( i , j ) = ( 65, 74 )

•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.
