3.1. Pixel Array And Pixel Color Pattern
The output image format of PAS202BCB/PAS202BBB is VGA (640x480 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.
