OM6800
VGA image sensor module
Rev. 01 — 22 November 2002
Preliminary data
1. General description
The OM6800 is a fixed-focus, highly integrated 1/4” CMOS colour imager module that
supports up to VGA resolution formats in a small package including a focused optical
system. It uses Philips SeeMOS™ technology for high sensitivity and low noise. The
sensor is digitally programmable via an I
2
C-bus serial interface and is equipped with
an integrated Programmable Gain Amplifier (PGA) and a 9-bit Analog-to-Digital
Converter (ADC). An embedded flexible timing generator enables easy matching to
various digital signal processing chips.
The module can operate as a master or as a slave. In the master mode, line and
frame synchronization output signals are generated by the module. In the slave
mode, the same pins are used as inputs for horizontal and vertical synchronization
signals.

8. Functional description
8.1 Architecture of the OM6800
8.1.1 Image section
The image section consists of a pixel array, vertical and horizontal selection circuitry,
an array of column amplifiers and a read amplifier. The pixel array contains
704 (H)
×
512 (V) pixels. The optical active pixels are covered by red, green and blue
colour filters arranged in a RGB-bayer structure. A micro-lens is placed on top of the
colour filters to increase the effective fill factor and consequently to achieve a higher
sensitivity. For black reference purposes a number of rows and columns are shielded
from light. Nine shielded rows are implemented at the top and bottom of the array.
24 black reference columns are available to the left and right. This results in an
optical active array of 656 (H)
×
494 (V) pixels.
The vertical selection circuitry has a double functionality. One is to select the line to
be read, the other is to select the line to reset, to determine the integration time
period. The integration time is determined by a rolling shutter. After a line has been
selected by the vertical selection circuitry and read by the column amplifiers, the
horizontal selection circuitry controls the selection of the pixel data that is to be
processed by the read amplifier.
The read amplifier performs Correlated Double Sampling (CDS) on the pixel data to
suppress Fixed Pattern Noise (FPN).
8.1.2 Programmable gain amplifier
The output signal of the read amplifier is applied to a PGA that has a gain range of
24 dB. The gain of the PGA can be programmed in 255 steps with an accuracy of
0.094 dB/step (typ.).
