An image representation in which each pixel is represented by a single sample value representing overall luminance (on a scale from black to white) PNG also permits an alpha sample to be stored for each pixel of a grayscale image
A term for a black & white photographic image or a scanner setting Refers to the range of 256 grey tones that make up the image
A scale of shades of gray from black to white Grayscale is used to represent colors when printing with black ink only
Environmental satellite scanners, rather than photographing a scene, scan a scene line-by-line measuring light or heat levels and transmitting this information as a video image via an amplitude modulated (AM) subcarrier contained in the satellite's FM signal The video image--a 2400 Hz tone--is amplitude modulated to correspond to the light and dark areas sensed, with the louder portion of the tone representing the lighter areas of the image and the lower portion of the tone representing the darker areas of the image Intermediate volumes form the shades of the gray scale (up to 256 shades) needed to complete the image This is an analog type of data transmission, and enables the assessment of such features as heat, light, temperature, and cloud heights
Shades of gray ranging from black to white In printing, grayscale uses only a black halftone plate
An 8-bit color mode that stores and displays images using 256 shades of gray that range from black to white Each color is defined as a single value between 0 and 255 where 0 is darkest (black) and 255 is lightest (white)
- A photo made up of varying tones of black and white Grayscale is synonymous with black and white
An image type that uses black, white, and a ranges of shades of gray The number of shades of gray depends on the number of bits per pixel The larger the number of shades of gray, the better the image will look, and the larger the file will be
