FUNCTIONS

Partial Scan Mode

The partial scan mode is a function for outputting part of the full images a region of interest on the whole image.

When the screen size needs to be set to the full size (DFW-SX900: SXGA, DFW-X700: XGA), data volume and system load can be decreased by setting the required screen size using the partial scan mode (Format_7).

Cutting size

Images can be cut only in rectangular shapes (including squares) and not with irregular features (convex and concave). Minimum unit size is shown in the table below. Minimum unit sizes can be combined and cut out together. The position of each unit can be specified but should not exceed the full size of the screen.

Note) This function can be used in both the normal mode and external trigger mode.

The frame rate is the same as the normal rate.
