DEFINITION

Classification: 348/256

Color TV (e.g., saturation):

(under subclass 255) Subject matter wherein the image signal being processed has a portion representing brightness (i.e., black and white), hue (i.e., wavelength), and saturation (i.e., purity from white) as contrasted with black, white, or gray.

(1) Note. Examples of saturation are: Both red and pink have the same wavelength, but red is saturated and pink is desaturated.
