...human eye is more sensitive to luminance than chrominance, so the loss of chrominance samples does not have a significant impact on picture quality. * 2 Chrominance blue values (Cb).

...g exploits the fact that humans are more sensitive to [[luminance]] than [[chrominance]] (color). The [[JPEG]] algorithm (amongst others) uses subsampling to thro

luminance/chrominance line Every fourth line, starting with line 0, contains both luminance (Y) and chrominance (C) data. The other lines only contain Y data.

...ndices into these tables (64 possible values for luminance and 16 for each chrominance component) are transmitted in the final bitstream. Each block can be encoded using a single chrominance sample or unique chrominance sample for each quadrant. Each quadrant has 16 luminance samples that can b

* C_b = "blue chrominance", or more precisely the color deviation from gray on a blue-yellow axis * C_r = "red chrominance", or more precisely the color deviation from gray on a red-cyan axis

...idden because no knowing indeo5 software performs any decomposition of the chrominance planes. ...EVER decomposed by the existing indeo5 software there is only one band per chrominance plane and therefore only one descriptor of this type.

TM1 uses a modified colorspace that embodies luminance (Y) and chrominance (C) information encoded as RGB deltas. Since Y information is more importan
