11. DESCRIPTION OF VARIOUS FUNCTIONS
11-1 AREA READOUT MODE, PHOTON NUMBER RESOLVING 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.
In Photon number resolving mode, 2×2, and 4×4 binning are available and implemented after the
photon number is resolved for each pixel.
