10-2 NORMAL AREA MODE
10-2-1 READOUT METHOD (SCAN MODE)
(1) Readout direction
The camera readout 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).

(2) Normal readout
Perform charge readout from camera individually for all pixels.
(3) Binning 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.
(4) 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.
