9-2

READOUT METHOD

(1) Full resolution readout
Perform charge readout from the CMOS image sensor individually for all pixels.
The frame rate of all pixels readout is 64.9 fps at maximum.
(2) 2×2 Digital binning readout
With this camera, 2×2 digital binning readout are available by adding the signal of
adjacent pixels in the digital domain. The flame rate of all pixel readout is same as 1x1
Normal readout.
(3) Sub-array readout
This camera supports sub-array-scanning operation in each mode.
Sub-array scanning is a procedure in which only a portion of the image is scanned. It is
possible to increase the frame rate by reducing the number of lines scanned. The
frame rate is determined only by vertical width, the horizontal width does not affect to
the frame rate.
The Sub-array scan setting is specified by the offset from 1
width, and the selectable range is as follows.
