This measurement was
directly taken on the video
line without an amplifier.
Table 2. Electro-Optical Characteristic
Notes: (1) Tint stands for the line scanning rate or the integration time. It is determined
by the time interval between two start pulses.
(2) f stands for the input clock frequency:
@ 1.0 MHz the total active line scan time for a A4 CIS module is 2.6 ms
of the line integration time.
@ 2.0 MHz the total active line scan time for a A4 CIS module is 1.3 ms
of the line integration time.
(3) Vp is a video output signal. It is converted from the signal current by
charging the video line capacitance. An amplifier buffers the video line
capacitance and allows line to charge, and the line is discharged through a
shunting switch that shunts it to ground. This amplifier also provides a
variable gain, typically 4 to 5 times the voltage that is measured on the video
line. Hence, as indicated in the schematic, the video output level is
adjustable.
(4) Up = [(Vpmax-Vp)/Vp]x100%
Or [(Vp-Vpmin)/Vp]x100%
Where Vp = (Vpmax+Vpmin)/2
Vpmax is the maximum pixel output voltage in the light.
Vpmin is the minimum pixel output voltage in the light.
Note: In the light means the sensor is exposed to the light.
(5) Vd = (Vdmax+Vdmin)/2
Vdmax is the maximum pixel output voltage in the dark.
Vdmin is the minimum pixel output voltage in the dark.
Note: In the dark means that sensor is light shielded and has no
exposure to the light.
(5) Ud = [(Vdmax-Vdmin)/Vd]x100%
