ICX205AL
Diagonal 8mm (Type 1/2) Progressive Scan CCD Image Sensor with Square Pixel for B/W Cameras
Description
The ICX205AL is a diagonal 8mm (Type 1/2)
interline CCD solid-state image sensor with a square
pixel array and 1.45M effective pixels. Progressive
scan allows all pixels' signals to be output
independently within approximately 1/7.5 second.
Also, the adoption of high frame rate readout mode
supports 30 frames per second. This chip features
an electronic shutter with variable charge-storage
time which makes it possible to realize full-frame still
image without a mechanical shutter. High sensitivity
and low dark current are achieved through the
adoption of HAD (Hole-Accumulation Diode) sensors.
This chip is suitable for applications such as
electronic still cameras, PC input cameras, etc.
20 pin DIP (Cer-DIP)
Features
• Progressive scan allows individual readout of the
image signals from all pixels.
• High horizontal and vertical resolution (both approx.
1024TV-lines) still image without a mechanical shutter.
• Supports high frame rate readout mode
(effective 256 lines output, 30 frame/s)
• Square pixel
• Horizontal drive frequency: 14.318MHz
• No voltage adjustments
(reset gate and substrate bias are not adjusted.)
• High resolution, high sensitivity, low dark current
• Low smear, excellent antiblooming characteristics
• Continuous variable-speed shutter

Measurement conditions
1) In the following measurements, the device drive conditions are at the typical values of the progressive scan
mode, bias and clock voltage conditions.
2) In the following measurements, spot blemishes are excluded and, unless otherwise specified, the optical
black level (OB) is used as the reference for the signal output, which is taken as the value measured at
point [∗B] of the measurement system.
Definition of standard imaging conditions
1) Standard imaging condition I:
Use a pattern box (luminance : 706cd/m2, color temperature of 3200K halogen source) as a subject.
(pattern for evaluation is not applicable.) Use a testing standard lens with CM500S (t = 1.0mm) as an IR cut
filter and image at F8. The luminous intensity to the sensor receiving surface at this point is defined as the
standard sensitivity testing luminous intensity.
2) Standard imaging condition II:
Image a light source (color temperature of 3200K) with a uniformity of brightness within 2% at all angles.
Use a testing standard lens with CM500S (t = 1.0mm) as an IR cut filter. The luminous intensity is adjusted
to the value indicated in each testing item by the lens diaphragm.
1. Sensitivity
Set to standard imaging condition I. After selecting the electronic shutter mode with a shutter speed of
1/250s, measure the signal output (VS) at the center of the screen, and substitute the value into the
following formula.

2. Saturation signal
Set to standard imaging condition II. After adjusting the luminous intensity to 10 times the intensity with the
average value of the signal output, 150mV, measure the minimum value of the signal output.
3. Smear
Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, first adjust the luminous
intensity to 500 times the intensity with the average value of the signal output, 150mV. Then after the
readout clock is stopped and the charge drain is executed by the electronic shutter at the respective H
blankings, measure the maximum value (Vsm [mV]) of the signal output and substitute the value into the
following formula.

4. Video signal shading
Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity
so that the average value of the signal output is 150mV. Then measure the maximum (Vmax [mV]) and
minimum (Vmin [mV]) values of the signal output and substitute the values into the following formula.
SH = (Vmax – Vmin)/150 × 100 [%]
5. Dark signal
Measure the average value of the signal output (Vdt [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.
