mathematical transformation of RGB designed solely for storage and
transmission. YCbCr images must be converted to RGB before they can
actually be displayed. In the YCbCr colorspace, the Y (luminance)
component represents the black & white portion of the original image, and
the Cb and Cr (chrominance) components represent the color portion of the
original image. Originally, the analog equivalent of this transformation
allowed the same signal to drive both black & white and color televisions,
but JPEG images use YCbCr primarily because it allows the color data to be
optionally subsampled for the purposes of reducing bandwidth or disk
space. YCbCr is the most common JPEG colorspace, and YCbCr JPEG images
can be compressed from and decompressed to any of the extended RGB pixel
formats or grayscale, or they can be decompressed to YUV planar images.</div>
