How to use Show YIQ Colors of Image
- 1. Upload the image to analyze. Add any image file. It's converted into YIQ, the color space historically used for NTSC analog television broadcasting.
- 2. Review the Y, I and Q panels. There are no settings to adjust. The Y panel shows luma while I and Q capture the in-phase and quadrature color information, each rendered as a grayscale strip.
- 3. Download the channel strips. Save the file with all three YIQ panels together for closer inspection.
When to use Show YIQ Colors of Image
Show YIQ Colors of Image splits a photo into its NTSC-derived luma, I and Q channels, the color model built to keep black-and-white television sets working alongside color broadcasts. Use it to see this historical color model applied to a real photo.
- Studying how black-and-white TVs read color signals. Understanding how NTSC kept backward compatibility with monochrome sets relies on the Y channel carrying brightness alone. Viewing it separately from I and Q shows exactly what an old black-and-white TV would have displayed.
- Restoring or analyzing archival video stills. A frame captured from old analog broadcast footage shows unusual color artifacts. Breaking it into Y, I and Q components can help identify whether the issue lives in luma or the chroma channels.
- Comparing broadcast color models for a project. A media history or engineering writeup wants to show YIQ alongside YCbCr for the same source image. Generating this breakdown gives a direct visual comparison between the two broadcast-era color models.
