Pixel Color Pattern Detail (Top Right Corner)
The output from the sensor is a Bayer pattern; alternate rows are a sequence of either
green and red pixels or blue and green pixels. The offset and gain stages of the analog
signal chain provide per-color control of the pixel data.
The control registers, timing and control, and digital processing functions shown in
Figure 1 on page 6 are partitioned into three logical parts:
• A sensor core that provides array control and data path corrections.
• A digital shading correction block to compensate for color/brightness shading intro-
• Functionality to support the SMIA standard. This includes a horizontal and vertical
The output FIFO prevents data bursts by keeping the data rate continuous. Program-
mable slew rates are also available to reduce the effect of electromagnetic interference
from the output interface.
The sensor core uses a Bayer color pattern, as shown in Figure 2. The even-numbered
rows contain green and red pixels; odd-numbered rows contain blue and green pixels.
Even-numbered columns contain green and blue pixels; odd-numbered columns
contain red and green pixels.
