PRELIMINARY
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.
