TCD1304AP
TOSHIBA CCD LINEAR IMAGE SENSOR CCD(Charge Coupled Device)
TCD1304AP
The TCD1304AP is a high sensitive and low dark current 3648 −elements linear image sensor. The sensor can be used for POS scanner. The device consist of sensitivity CCD chip. The TCD1304AP has electronic shutter function (ICG). Electronic shutter funtion can keep always output voltage constant that vary with intensity of lights.

Note 2: Measured at 50% of SE (Typ.)
Definition of PRNU: PRNU = Dc ´100%
c
Where ? is average of total signal outputs and ,? is the maximum deviation from ? under uniform illumination.
Note 3: Measured at 50% of SE (Typ.)
RI is defined as follows:
3647
å cn - cn + 1
RI = n=1
´ 100%
3647·c
Where ? n and ? n+1 are signal outputs of each pixel. ? is average of total signal outputs.
Note 4: VSAT is defined as minimum saturation output voltage of all effective pixels. Note 5: VMDK is defined as maximum dark signal voltage of all effective pixels.

Note 6: Definition of DR : DR = VSAT
VMDK
VMDK is proportional to tINT (Integration time).
So the shorter tINT condition makes wider DR value.
