3. Output Format

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.

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.
