ICX098AK
Diagonal 4.5mm (Type 1/4) Progressive Scan CCD Image Sensor with Square Pixel for Color Cameras
Description
The ICX098AK is a diagonal 4.5mm (Type 1/4)
interline CCD solid-state image sensor with a square
pixel array which supports VGA format. Progressive
scan allows all pixels signals to be output
independently within approximately 1/30 second.
Also, the adoption of monitoring mode allows output
to an NTSC monitor without passing through the
memory. 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 resolution and high color reproductivity
are achieved through the use of R, G, B primary color
mosaic filters. Further, 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.
14 pin DIP (Plastic)

5. Uniformity between video signal channels
After measuring 4, measure the maximum (Rmax [mV]) and minimum (Rmin [mV]) values of the R signal
and the maximum (Bmax [mV]) and minimum (Bmin [mV]) values of the B signal, and substitute the values
into the following formula.
∆Srg = (Rmax – Rmin)/150 × 100 [%]
∆Sbg = (Bmax – Bmin)/150 × 100 [%]
6. 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.
7. Dark signal shading
After measuring 6, measure the maximum (Vdmax [mV]) and minimum (Vdmin [mV]) values of the dark
signal output and substitute the values into the following formula.
∆Vdt = Vdmax – Vdmin [mV]
8. Line crawl
Set to standard imaging condition II. Adjusting the luminous intensity so that the average value of the Gr
signal output is 150mV, and then insert R, G, and B filters and measure the difference between G signal
lines (∆Glr, ∆Glg, ∆Glb [mV]) as well as the average value of the G signal output (Gar, Gag, Gab).

9. Lag
Adjust the Gr signal output value generated by strobe light to 150mV. After setting the strobe light so that it
strobes with the following timing, measure the residual signal (Vlag). Substitute the value into the following
formula.
Lag = (Vlag/150) × 100 [%]
