LZ34C10  
1/4-type Color CMOS Image Sensor with  
110 k Pixels  
LZ34C10  
DESCRIPTION  
PIN CONNECTIONS  
The LZ34C10 is a 1/4-type (4.5 mm) solid-state  
color image sensor that consists of PN photo-  
diodes and CMOS (Complementary Metal Oxide  
Semi-conductor) 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 110 000 pixels  
(393 horizontal x 299 vertical), the sensor provides  
a stable digital color image with extremely low  
power consumption.

NOTES :  
1. The average output voltage of G signal under uniform  
illumination. The standard exposure conditions are  
defined as when VO is 150 mV.  
5. The image area is divided into 10 x 10 segments under  
non-exposure conditions. DSNU is defined by (Vdmax –  
Vdmin), where Vdmax and Vdmin are the maximum and  
minimum values of each segment's voltage respectively.  
6. The average output voltage of G signal when a 1 000  
lux light source with a 90 % reflector is imaged by a lens  
of F4, F50 mm.  
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.  
7. Total current of analog and digital power supplies, in the  
dark and at the standard load conditions.  
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.  
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>.  
4. The difference between average output voltage of the  
effective area and that of the OB (A) area, under non-  
exposure conditions.
