Operational modes

The FXA 1012 is designed for high-resolution digital photography

with real time monitoring at reduced resolution. Two different modes

of operation make this possible.

In the still picture mode the high-resolution image is read-out directly.

A mechanical shutter ensures a 100% smear-free image with a

resolution of 1600 (H) x 1280 (V).

In the monitoring mode, images with reduced vertical resolution are

produced that are suitable for LCD displays. These images can have

for example, 120, 240 or 256 lines at up to 40 images per second.
