∗1 The saturation signal level is 450mV or more by performing pull-down CSUB pin at 1.3kΩ resistor.

For high frame rate readout mode, it is 800mV.

∗2 After closing the mechanical shutter, the smear can be reduced to below the detection limit by performing

vertical register sweep operation.

∗3 Excludes vertical dark signal shading caused by vertical register high-speed transfer.
