TC281
1036- × 1010-PIXEL CCD IMAGE SENSOR
SOCS058D – JUNE 1996 – REVISED MARCH 2003
spurious nonuniformity specification
The spurious nonuniformity specification of the TC281 CCD grade – 30 is based on several performance
characteristics:
D Amplitude of the nonuniform line or pixel signal
D Polarity of the nonuniform pixel signal
– Black
– White
D Column signal amplitude
The CCD sensors are characterized in both an illuminated condition and a dark condition. In the dark condition,
the nonuniformity is specified in terms of absolute amplitude, as shown in Figure 6. In the illuminated condition,
the nonuniformity is specified as a percentage of the total amplitude, as shown in Figure 7.
