Frequently Asked Questions

Common questions about YIQ color channel extraction

What is the YIQ color space?

YIQ is the color space used by the NTSC color TV system, employed mainly in North and Central America and Japan. Y represents the luminance (brightness) information, while I and Q represent the chrominance (color) information.

Why use YIQ instead of RGB?

YIQ is designed to take advantage of human color response characteristics. The human eye is more sensitive to changes in luminance than to changes in hue or saturation, which allowed NTSC to broadcast more luminance detail than chrominance detail.

How is Y calculated?

Y (Luminance) is calculated as: Y = 0.299R + 0.587G + 0.114B. This represents the weighted brightness of the image as perceived by the human eye.

Are my images secure?

Yes. All color channel extraction is performed entirely within your browser using the Canvas API. No image data is ever uploaded to our servers.
