10-4 READOUT METHODS
The readout methods can set units for reading out images. In the Sub-array readout, the readout area
is also set. The methods have the below.

Designated area
(1) Normal readout (Full resolution readout)
Perform charge readout from camera individually for all pixels.
(2) Binning readout
With this camera, 2×2 binning and 4×4 binning readout are available by adding the signal of
adjacent pixels in the digital domain. Binning readout is a method for achieving high sensitivity in
exchange for losing resolution. The mode is not supported at Lightsheet Readout Mode.
(3) Sub-array readout
The Sub-array readout is a procedure only a region of interest is scanned. It is possible to
increase the frame rate by reducing the number of vertical lines scanned. (when using the
“DCAM-API” software.) In the readout, binning configuration is enabled.
