Features Description

Image Section
The image section consists of a pixel array, vertical and horizontal selection circuitry, a bench of
column amplifiers and a read amplifier. The pixel array contains 708(H) × 494(V) pixels. The pix-
els are covered by red, green and blue color filters arranged in a RGB Bayer structure. A micro-
lens is placed on top of the color filters to increase the effective fill factor for higher sensitivity.
For black reference purposes a number of rows and columns are shielded from light.
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 and read by the column amplifiers,
the horizontal selection circuitry takes care of the pixel data selection that is to be processed by
the read amplifier.
The read amplifier performs Correlated Double Sampling (CDS) to suppress Fixed Pattern
Noise (FPN).
