LZ34B1B
1/4-type Color CMOS Image Sensor with
350 k Pixels
DESCRIPTION
The LZ34B1B is a 1/4-type (4.5 mm) solid-state
color image sensor that consists of PN photo-
diodes and CMOS (Complementary Metal Oxide
Semiconductor) devices. The sensor further
includes a timing generator (TG), a correlated
double sampling (CDS) circuit, an auto gain control
(AGC) circuit and an analog-to-digital converter
(ADC) circuit. With approximately 350 000 pixels
(703 horizontal x 499 vertical), the sensor provides
a stable digital color image with extremely low
power consumption.
FEATURES
• Progressive scan
• Square pixel
• Compatible with VGA standard
• Number of image pixels : 655 (H) x 493 (V)
• Number of optical black pixels
– Horizontal : 24 front and 24 rear
– Vertical : 3 front and 3 rear
• Pixel pitch : 5.6 µm (H) x 5.6 µm (V)
• R, G, and B primary color mosaic filters
• Image inversion function (horizontally and/or
vertically)
• Available for two types of power save mode
– AGC and AD circuits become power-off with
serial data
– All circuits become power-off with STBY pin
• Monitoring mode
• Analog output and 8-bit digital output
• Variable gain control (3 to 30 dB)
• Variable electronic focal plane shutter (1/15 to
1/7 875 s)
• Single +2.8 V power supply
• Package : 36-pin LCC* (N-LCC036-S425B)
* Leadless Chip Carrier

NOTES :
1. The average output voltage of G signal under uniform
illumination. The standard exposure conditions are
defined as when VO is 150 mV.
2. The image area is divided into 10 x 10 segments under
the standard exposure conditions. Each segment's
voltage is the average output voltage of all pixels within
the segment. PRNU is defined by (Vmax – Vmin)/VO,
where Vmax and Vmin are the maximum and minimum
values of each segment's voltage respectively.
3. The image area is divided into 10 x 10 segments. Each
segment's voltage is the average output voltage of all
pixels within the segment. VSAT is the minimum
segment's voltage under 10 times exposure of the
standard exposure conditions.
4. The difference between average output voltage of the
image area and that of the OB area, under non-
exposure conditions.
5. The average output voltage of G signal when a 500 lux
light source with a 90% reflector is imaged by a lens of
F4, F50 mm.
6. Total current of analog and digital power supplies, in the
dark and at the standard load conditions.
7. Total current of power supply in standby mode. (Pin
No.9 (STBY) is fixed to "H" level and other input pins are
fixed to "H" level or "L" level.)
8. One mean horizontal line signal <bi> is obtained by
adding all the horizontal line signals <aij> vertically and
dividing them by the line number. <xi> is the deviation of
the center pixel from the average of successive 5 pixels
in <bi>. VFPN is the maximum absolute value of <xi>.
