11. DESCRIPTION OF VARIOUS FUNCTIONS
11-1 AREA READOUT MODE
11-1-1 CAMERA READOUT MODES (READOUT DIRECTION)
The camera reads out in two line pairs simultaneously.
11-1-2 READOUT METHODS
(1) 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 where only a region of interest is scanned. It is possible to
increase the frame rate by reducing the number of vertical lines scanned. In sub-array readout,
binning can also be 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-API.
•
Refer to 10-1-4 "FRAME RATE CALCULATION" about the frame rate of each readout mode.
