YIQ Adjust

Allows color adjustment in YIQ color space. The YIQ color space definition was formerly used to describe an NTSC broadcast signal.

Adjust this filter using the parameter controls in the Filters Inspector:

  • Y: Sets the intensity of the Y color channel. (Y represents the luma component/grayscale information.)

  • I: Sets the phase of the I color channel. (I represents the hue component/chroma information.)

  • Q: Sets the phase of the Q color channel. (Q represents the saturation component/chroma information.)

  • Mix: Sets the percentage of the original image to be blended with the color-corrected image.
