Table 5: Pixel Data Format for 16 bpp (10 valid data bits) for all Lw, Lt and Lg series cameras
For monochrome cameras, each byte (8bpp) or word (16bpp) represents one pixel in the image.
For color cameras, each pixel is covered by one Bayer color filter. An example of an RGGB Bayer filter is shown in
Figure 25. Each 2x2 sub mosaic contains 2 green, 1 blue and 1 red filter. In Figure 25, pixel (0,0) has a red color filter
that filters light in the red wavelength range; pixel(0,1), pixel(16,0) and pixel(16,1) filter light in the green, green and blue
wavelength ranges respectively. In other words, each pixel will represent one of the RGB colors. The raw image data
from a color sensor will have all pixel values corresponds to the intensity of light filtered by the Bayer filter, also referred
as the raw Bayer format. The raw image data is not bitmap data. To get the bitmap data, a conversion is needed.
