77 / 126 page  DocID023597 Rev 11 77/126 VG6640, VD6640 Video system 125 7 Video system 7.1 Image and video capabilities The image sensor supports various video modes ranging from full field of view@45 fps to HD video, 720p@60 fps. Example configurations and output interface data rates are given in Table 35. 7.2 Bayer pattern The three color (red, green, and blue) filters are arranged over the pixel array in a repeated 2 x 2 arrangement known as the Bayer pattern. When the sensor array is read, the output order of red, green, blue depends on the settings of vertical flip and horizontal mirror. Figure 22 shows the read-out order for a sensor of 980 rows by 1304 columns, for the default settings of vertical flip and horizontal mirror (both disabled). Lines are read from left to right, then from top to bottom. Hence the order is green, red, green, red, and so on for the first line, followed by blue, green, blue, green, and so on for the second line. If vertical flip is enabled, the first line order becomes blue, green, blue, green, and so on. If horizontal mirror is enabled, the first line order becomes red, green, red, green, and so on.
