KLI-4104
Linear CCD Image Sensor
Description
The KLI−4104 Image Sensor is a multi-spectral, linear solid-state
image sensor for color scanning applications where fast operation and
high resolution are required. The imager consists of three parallel
linear photodiode arrays, each with 4,080 active photosites for the
output of red, green and blue (R, G, and B) signals. The sensor
contains a fourth channel for luminance information. This array has
8,160 pixels segmented to transfer out data through one of four
luminance outputs. This device offers high sensitivity, high data rates,
low noise and negligible lag. Individual electronic exposure control
for each of the Chroma and the Luma channel is provided, allowing
the KLI−4104 sensor to be used under a variety of illumination
conditions.

Zero re-phasing errors, in the final color image, is
accomplished by having effectively center-aligned
sampling apertures (pixels) in the luminance and chroma
channels.
Even though the luminance and chroma channels are
physically edge-aligned vertically, when scan motion is
introduced it has a “center-weighted” sampling effect at the
full resolution scan speed.
The following pixel alignment diagram explains in more
detail the reason for being edge-aligned in the vertical
direction and how the 12.25 line spacing (122.5 mm) works
out to achieve zero re-phasing errors at full resolution.

Figure 4. Pixel Alignment Diagram
The y-axis of the diagram is the direction of scanning
motion (luminance-leading scan in this case). Note on the
x-axis, that the luminance sampling rate (represented by the
arrows) is 2× that of the chroma channel. Also note the
horizontal dotted line, showing that the arrows are
synchronized, depicting the effective center-aligned
sampling of luminance and chroma channels after 25
luminance lines have been acquired.
This equates to zero re-phasing error between luminance
and chroma signals at full resolution.
If scan speed is changed to lower the vertical resolution,
a small re-phasing error may be introduced.
High Speed Scanning
The KLI−4104 sensor is ideal for applications such as
high-speed document scanning.
High data throughput is achieved by having a total of 7
outputs, 4 outputs on the luminance channel (4 ⋅ 30 MHz =
120 MHz total data rate), and 1 output per chroma channel
(30 MHz each).
Readout of the pixel data for the luminance channel is
accomplished through the use of two CCD shift registers in
an odd/even pixel readout configuration (4 outputs total).
A system can be designed with the KLI−4104 to achieve
high-resolution color scans (600 dpi), when scanning the
longer length side of A4 paper size at over 150 pages per
minute.
