Image and video size capabilities

The VS6955CA supports various video modes ranging from VGA@120 fps to HD formats

like 3.8 Mpixel @ 42 fps, 1080p30 and 720p30.

7.3

Bayer pattern

The three color (Red, Green, Blue) filters are arranged over the pixel array in a repeated

2 x 2 arrangement known as the Bayer Pattern. When the pixel array is read, the output

order of red, green, blue depends on the settings of vertical flip and horizontal mirror.

Figure 25 shows the read-out order for the default settings of vertical flip and horizontal

mirror both turned off. Vertical flip changes the first line to be output from a green/red line to

a blue/green line and horizontal mirror changes the sequence within a line, for example,

green/red to red/green.

As shown in Figure 25, the first pixel to be readout from the imaging array is green followed

by red.
