The additional border columns and rows are included to enable complete color reconstruction of the

final 640 by 480 sized array.

Microlens

Microlenses placed above the visible pixels improve light gathering capability hence improving

sensitivity.

Sensor data overview

Sensor data is output on a 5-wire bus. As well as pixel data there are embedded codes at the start

and end of every video line. These codes are always preceded by an escape sequence which is

guaranteed not to appear in the video data itself.
