YCrCb Values For Various Colors? ›

YCrCb or YCbCr

The YCrCb stands for Luminance (sometimes you can see Y' as luma), Red-difference and Blue-difference chroma components. The YCrCb ranges are: 0 > Y > 255. 0 > Cr > 255.

YCrCb or YCbCr

The YCrCb stands for Luminance (sometimes you can see Y' as luma), Red-difference and Blue-difference chroma components. The YCrCb ranges are: 0 > Y > 255. 0 > Cr > 255.

YCbCr, Y′CbCr, or Y Pb/Cb Pr/Cr, also written as YC_BC_R or Y′C_BC_R, is a family of color spaces used as a part of the color image pipeline in video and digital photography systems. Y′ is the luma component and C_B and C_R are the blue-difference and red-difference chroma components.

YCbCr. The YCbCr color space is widely used for digital video. In this format, luminance information is stored as a single component (Y) and chrominance information is stored as two color-difference components (Cb and Cr).

The YCbCr and RGB color spaces have distinct applications. While RGB represents color through combinations of red, green, and blue light, YCbCr represents color in terms of one luma component (Y) and two chroma components (Cb and Cr).

Optimizing Video Output

Users should select either YCbCr color space or RGB High to match their television's specification. RGB High is often preferred for its fidelity, especially when used with TVs that handle a full RGB signal well, presenting a picture without alterations in contrast or brightness range.

There's basically no difference between RGB 4:4:4 and YCbCr 4:4:4 IF the latter option supports full range. When it doesn't, you're limited to a color ramp of 16-235 vs 0-255. But, you'll always want to use RGB on computer monitors because it's been the standard since forever.

A CMYK image has four channels: cyan, magenta, yellow, and key (black). CMYK is the standard for print, where subtractive coloring is used. A 32-bit CMYK image (the industry standard as of 2005) is made of four 8-bit channels, one for cyan, one for magenta, one for yellow, and one for key color (typically is black).

An RGB image has three channels: red, green, and blue. An HSL image has three channels: hue, saturation, and lightness. Although you cannot create or edit an image using the CMYK model, you can still split the image into four channels: cyan, magenta, yellow, and black.

Full name. Uncompressed YCbCr Video Picture Stream Family (4:2:2) Description. A digital, color-difference component video picture stream in which the two chroma components are sampled at half the rate of luma.

What is the 4 color format? ›

These four colors are Cyan, Magenta, Yellow, and Black- which are known collectively as CMYK. In fact, 4-Color Process printing is frequently referred to as CMYK printing. It is also known as Four Color Printing, 4CP, Full Color Printing, or simply Process Printing.

YCbCr422 / 420 will have fringing on text on the desktop and in games - it's only suitable for video which is typically recorded in 4:2:0. YCbCr422 / 420 10-bit is worse than RGB 8-bit in every way. Even YCbCr444 will require black level expansion and is worse than RGB, so just use RGB.

From what I understand YCbCr709 is a native color space for most HD file based codecs, and offers more detail in white and black areas.

If your design will end up on digital screens like computer monitors or TVs, you should use RGB. If you need to physically print anything like product labels, brochures, or more, you should use CMYK. Using the wrong format can lead to inaccurate color representations.

RGB = ycbcr2rgb( YCBCR ) converts the luminance (Y) and chrominance (Cb and Cr) values of a YCbCr image to red, green, and blue values of an RGB image.

YUV, YPbPr and YCbCr are all basically same, but just with different scale factors for the signals. YUV signals are used when encoding/decoding analog composite video, YPbPr signals exists at analog component video interface and YCbCr signals are digital numbers.

Simply put, CMYK is the color mode intended for printing with ink, such as business card designs and posters. RGB is the color mode intended for digital communication, such as websites and television. The more color added in CMYK mode, the darker the result. The more color added to RGB, the lighter the result.

For most images, pixel values are integers that range from 0 (black) to 255 (white). The 256 possible gray intensity values are shown below. The range of intensity values from 0 (black) to 255 (white).
