ICX068AKB
Diagonal 4.5mm (Type 1/4) CCD Image Sensor for NTSC Color Video Cameras
Description
The ICX068AKB is an interline CCD solid-state
image sensor suitable for NTSC color video cameras.
High resolution is achieved through the use of Ye, Cy,
Mg, and G complementary color mosaic filters. At the
same time, high sensitivity and low dark current are
achieved through the adoption of HAD (Hole-
Accumulation Diode) sensors.
This chip features a field period readout system and
an electronic shutter with variable charge-storage
time.
Also, this outline is miniaturized by using original
package.
Features
• Maximum package dimensions: φ8mm
• High resolution, high sensitivity and low dark current
• Horizontal register: 3.6 to 5.0V drive
• No voltage adjustment
(Reset gate and substrate bias are not adjusted.)
• Low smear
• Excellent antiblooming characteristics
• Continuous variable-speed shutter
• Ye, Cy, Mg, and G complementary color mosaic filters on chip

7. Dark signal shading
After measuring 6, measure the maximum (Ydmax [mV]) and minimum (Ydmin [mV]) values of the Y signal
output and substitute the values into the following formula.
∆Ydt = Ydmax – Ydmin [mV]
8. Flicker
1) Fy
Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Y signal
output is 200mV, and then measure the difference in the signal level between fields (∆Yf [mV]). Then
substitute the value into the following formula.
Fy = (∆Yf/200) × 100 [%]
2) Fcr, Fcb
Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Y signal
output is 200mV, insert an R or B filter, and then measure both the difference in the signal level between
fields of the chroma signal (∆Cr, ∆Cb) as well as the average value of the chroma signal output (CAr, CAb).
Substitute the values into the following formula.
Fci = (∆Ci/CAi) × 100 [%] (i = r, b)
9. Line crawls
Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Y signal
output is 200mV, and then insert a white subject and R, G, and B filters and measure the difference
between Y signal lines for the same field (∆Ylw, ∆Ylr, ∆Ylg, ∆Ylb [mV]). Substitute the values into the
following formula.
Lci = (∆Yli/200) × 100 [%] (i = w, r, g, b)
10. Lag
Adjust the Y signal output value generated by strobe light to 200mV. After setting the strobe light so that it
strobes with the following timing, measure the residual signal (Ylag). Substitute the value into the following
formula.
Lag = (Ylag/200) × 100 [%]
