3. Pixel Array And Pixel Color Pattern
3.1. Pixel array and pixel color pattern
The output image format of PAS109B is QQVGA (164x124 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.
