How to use Show YCbCr / YPbPr Colors of Image
- 1. Upload the image to analyze. Add any image file. It's converted into YCbCr, the luma-and-color-difference model used by JPEG and most video codecs, following the BT.601 convention.
- 2. Review the luma, Cb and Cr panels. There are no settings to adjust. The Y panel shows brightness while Cb and Cr capture the blue-difference and red-difference color information, each rendered as a grayscale strip.
- 3. Download the channel strips. Save the file with all three panels together for a closer look at the luma and chroma split.
When to use Show YCbCr / YPbPr Colors of Image
Show YCbCr / YPbPr Colors of Image separates a photo into luma and the two color-difference channels used internally by JPEG compression and analog and digital video. It's for anyone who wants to see the actual channel structure that codecs work with rather than RGB.
- Understanding why JPEG compresses color more. JPEG compresses the Cb and Cr channels more aggressively than luma because eyes are less sensitive to color detail. Viewing the three channels separately shows why that tradeoff works visually.
- Debugging a video color pipeline. A video processing script works with YCbCr internally and a specific frame is producing odd colors. Splitting that frame into its Y, Cb and Cr components helps isolate which channel is off.
- Teaching the difference between luma and color. Explaining that brightness and color information are handled separately in most compression and broadcast formats is clearer with a real image split into its Y, Cb and Cr channels.
