ICX414AL
Diagonal 8mm (Type 1/2) Progressive Scan CCD Solid-state Image Sensor with Square Pixel for EIA B/W Cameras
Description
The ICX414AL is a diagonal 8mm (Type 1/2) interline
CCD solid-state image sensor with a square pixel
array suitable for EIA black-and-white cameras.
Progressive scan allows all pixel's signals to be output
independently within approximately 1/60 second. This
chip features an electronic shutter with variable
charge-storage time which makes it possible to
realize full-frame still images without a mechanical
shutter. Square pixel makes this device suitable for
image input and processing applications. High
sensitivity and low dark current are achieved through
the adoption of the HAD (Hole-Accumulation Diode)
sensors.
This chip is suitable for applications such as FA
and surveillance cameras.
Features
• Progressive scan allows individual readout of the image signals
from all pixels.
• High vertical resolution (480 TV-lines) still images without a
mechanical shutter
• Square pixel
• Supports VGA format
• Horizontal drive frequency: 24.54MHz (Max.)
• No voltage adjustments (reset gate and substrate bias are not
adjusted.)
• High resolution, high sensitivity, low dark current
• Continuous variable-speed shutter
• Low smear
• Excellent anti-blooming characteristics

Image sensor readout mode
The diagram below shows the output methods for the following three readout modes.
(1) Progressive scan mode
(2) Field readout mode
VOUT
VOUT
1. Progressive scan mode
In this mode, all pixel signals are output in non-interlace format in 1/60s.
All pixel signals within the same exposure period are read out simultaneously, making this mode suitable for
high resolution image capturing.
2. Field readout mode
All pixels are readout, 2-line transfer is performed during H blanking period and 2 pixels are added by
horizontal register. (However, guarantees only at the time of a 12MHz drive.)
(3) Center scan mode
Undesired portions (Swept by vertical register high-speed transfer)
Picture center cut-out portion
3. Center scan mode
This is the center scan mode using the progressive scan method.
The undesired portions are swept by vertical register high-speed transfer, and the picture center portion is
cut out.
There are the mode (120 frames/s) which outputs 222 lines of an output line portion, and the mode
(240 frames/s) which outputs 76 lines.
