Functions
Partial Scan
Only the area selected from the effective pixel area can
be read out. Clearing unnecessary parts at high-speed
allows high-speed reading. The area size is selected by
the HEIGHT and WIDTH commands, and the read
beginning point is selected by the OFFSETX and
OFFSETY commands. Using the ROI command, you
can set HEIGHT, WIDTH, OFFSETX and OFFSETY at
the same time. Reducing HEIGHT increases the frame
rate, but changing WIDTH does not change the frame
rate. Partial scan can be set with or without a trigger.
Binning can be used at the same time.
OFFSETX and OFFSETY relate to WIDTH and
HEIGHT as follows:
O WIDTH
≤
WIDTH (maximum value)
O HEIGHT
≤
HEIGHT (maximum value)
Configurable range
Configurable values
OFFSETX, WIDTH: in 16 step
OFFSETX, HEIGHT: in 4 step
Notes
• Since the shutter setting has priority, use a shutter
speed high enough to enable partial scan at a higher
frame rate.
• When using the binning function, the configurable
range will be 1/2.
