Some of the image sensors can output the standard video formats by cropping or binning the pixels, the others may
output non-standard resolutions. The important thing is to obtain the information of the Total Horizontal Samples,
Total Vertical Lines and frame Refresh Rate. We will discuss how to calculate the bandwidth based on the above
information.
2.2. Color Depth
Color depth, also known as bit depth, can be either referred to as bits-per-pixel (bpp) which specifies the number of
bits used for a single pixel, or referred to as bits-per-component (bpc) which specifies the number of bits used to
represent each color component of a single pixel. Deep color supports 30/36/48-bit for three RGB colors. In this
document, the term Pixel Size is equivalent to the color depth in bits-per-pixel. For example, the pixel size of a 30-bit
deep color RGB is defined as 30 bits per pixel, or 10 bits per color component.
