(row 0, column 0) is covered by a red filter, (row 0, column 1) and (row 1, column 0) by green filters, and (row 1, column 1) by a blue filter. since each pixel only gets part of the frequency band, the data need further processing (i.e., color interpolation and color correction) in order to approximate the full visible spectrum. figure 2. color filter bayer pattern exposure and gain control the brightness of the scene may change by a great amount that renders the captured image either over-exposed or under-exposed. to accommodate for different brightness, the user may change the exposure time by adjusting the ad_expose_timeh, and ad_expose_timel. the exposure time is measured in terms of the time to read out one line of data, which is equal to 64 s (assuming the line length is 770 @ 24 mhz). if the number of lines per frame is set at 520 (the default), the exposure time can vary from 1 to 519 lines. 50/60hz anti-flickering control to eliminate the flickering caused by the 50hz or 60hz light source normally found indoor, an anti-flickering control circuit is build in. the selection is between off and on. when it is on, then the selection is between 50 or 60hz. r r g g r r g g g b g b g b g b r r g g r r g g g b g b g b g b
