3. Pixel Array And Pixel Color Pattern
The output image format of PAS106BCA-323/PAS106BBA -323 is CIF (352x288 pixel array). To provide the
co-processor with the extra information it needs for interpolation at the edges of the pixel array, an border of 2
pixels on all 4 sides of the array are available. Fig 3.1. illustrates the pixel array and pixel color pattern.

Note:
1. Pixel color pattern does not apply to monochrome sensor.
2. Pixel read-out proceeds from left to right, and from bottom row to top row.
3. Pixel array not drawn to scale.
