11. DESCRIPTION OF VARIOUS FUNCTIONS
11-1 NORMAL AREA MODE
11-1-1 CAMERA READOUT MODES (READOUT DIRECTION)
The camera reads out the image sensor from the center line to the top and from the center line to the
bottom simultaneously (center line is depicted in red line in the diagram).

11-1-2 READOUT METHODS
(1) Normal readout (Full resolution readout mode; 1×1 readout)
Perform charge readout from camera individually for all pixels.
(2) Binning readout (2×2 / 4×4 readout)
With this camera, 2×2 binning readout and 4×4 binning 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.
(3) Sub-array readout
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 a target area is placed in
the center of the screen, sub-array readout can perform the fastest readout. In sub-array readout,
binning configuration is enabled.
Size and a position of the readout area can be configured according to the table below.

Minimum settable step of the size and position on the table is in only the case that the camera is used
with DCAM.
