ICX238AKC
Diagonal 3mm (Type 1/6) CCD Image Sensor for NTSC Color Video Cameras
Description
The ICX238AKC is an interline CCD solid-state
image sensor suitable for NTSC small color video
cameras. High resolution is achieved hrough the use
of Ye, Cy, Mg, and G complementary color mosaic
filters.
This chip features a field period readout system and
an electronic shutter with variable charge-storage time.
The package is the smallest 12-pin SON (LCC).
12 pin SON (Plastic)
Features
• High sensitivity and low smear
• Horizontal register: 3.3 to 5.0V drive
• Reset gate:
3.3 to 5.0V drive
• No voltage adjustment
(Reset gate and substrate bias are not adjusted.)
• Low dark current and excellent antiblooming characteristics
• Continuous variable-speed shutter
• Recommended range of exit pupil distance: –10mm to –∞
• Ye, Cy, Mg, and G complementary color mosaic filters on chip
• 12-pin MID SON (LCC) package

5. Video signal shading
Set to standard imaging condition III. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity
so that the average value of the Y signal output is 200mV. Then measure the maximum (Ymax [mV]) and
minimum (Ymin [mV]) values of the Y signal and substitute the values into the following formula.
SHy = (Ymax – Ymin)/200 × 100 [%]
6. Uniformity between video signal channels
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 maximum (Crmax, Cbmax [mV]) and minimum (Crmin, Cbmin
[mV]) values of the R – Y and B – Y channels of the chroma signal and substitute the values into the
following formula.
∆Sr = | (Crmax – Crmin)/200 | × 100 [%]
∆Sb = | (Cbmax – Cbmin)/200 | × 100 [%]
7. Dark signal
Measure the average value of the Y signal output (Ydt [mV]) with the device ambient temperature 60°C and
the device in the light-obstructed state, using the horizontal idle transfer level as a reference.
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)
