The final YUV/YCbCr image uses this filter pattern to interpolate each pixelsBG or GR color from the light striking the cell directly, as well as from the light striking thesurrounding cells. The Raw RGB image does not have any image processing.Table 2-1 lists all OV9650 output formats.2 图像传感器阵列ov9650摄像头芯片 有效阵列规模为 1300列乘以1028行（1,336,400像素）。像素单元本身是相同的，但是线交替地安排了bg/gr 颜色模式的RG
