Polaroid CSGX36BC3, CSGS20BC2, CSGU15BC18, CSGV90BC3, CSGS15BC23 instruction manual Minimum unit size

(7) Scalable mode

This camera has the scalable mode that can read out defined area of the screen. Only continuous rectangle units can be selected, concave or convex shape cannot be selected.

- Window size: {A x m(H)} x {B x n(V)}

*A and B are minimum unit size.

*m, n=integer

*The image of maximum unit size or less can be selected.

*Only one window can be selected.

- Start address:		{32 x i(H)} x {24 x j(V)}

*i, j=integer

*The image of maximum unit size or less can be selected.

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.

Notes on scalable mode:

-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.
