For Bayer pixel format.
If the color camera uses one of the Bayer pixel formats, it outputs 8, 10, or 12 bits of data per pixel. The pixel data is not processed or interpolated in any way. For each pixel covered with a red filter, you get 8, 10, or 12 bits of red data. For each pixel covered with a green filter, you get 8, 10, or 12 bits of green data. For each pixel covered with a blue filter, you get 8, 10, or 12 bits of blue data. This type of pixel data is sometimes referred to as "raw" output.
For YUV formats.
If a color camera uses this format, each pixel value in the captured image goes through a conversion process as it exits the sensor and passes through the camera. This process yields Y, U, and V color information for each pixel value. The values for U and V normally range from -128 to +127. Because of the camera transfers U values and V values with unsigned integers, 128 is added to each U value and V value before they are transferred from the camera. This way, values from 0 to 255 can be transferred.
For RGB and BGR Formats
If a color camera uses the RGB 8 or BGR 8 pixel format, the camera outputs 8 bit of red data, 8 bit of green data, and 8 bit of blue data for each pixel in the acquired frame.
The pixel formats differ by the output sequences for the color data (red, green, blue or blue, green, red).
