Definition of gray scale in English English dictionary
A range of grays with regular density intervals from white to black A gray scale image is an image that contains various levels (or shades) of gray
A strip of light to dark gray tones placed at the side of original copy when photographed to measure tonal range (gamma) and contrast
Gray scale can be viewed as a degenerate case of pseudo color, in which case the red, green, and blue values in any given color map entry are equal, thus producing shades of gray The gray values can be changed dynamically
Variations of values from white, through shades of gray, to black in a digitized image with black assigned the value of zero and white the value of one
An optical pattern consisting of discrete steps or shades of gray between black and white (188)
The range of tones, from bright white to pitch black that can be reproduced in a film and print
Generally refers to a monochrome ordering of 256 shades between black and white which are assigned to raster picture elements (pixels) according to reflected light, heat, and/or other relative intensity measurements Most common digital display option for scanned black and white orthophotos
A strip of standard gray tones ranging from white to black, to measure the tonal range obtained during photography or plate exposure See also: Sensitivity Guide to top
1 As applied to an image, composed of (discrete) shades of gray If the pixels of a gray-scale image have n bits, they may take values from zero, representing black, up to 2-1, representing white Intermediate values represent increasingly light shades of gray If n=1, the image is not called gray-scale but black-and-white (or a line drawing) 2 A range of accurately known shades of gray printed out for use in calibrating those shades on a display or printer
The tonal range from a very light gray (1% dot) up to solid black (100% dot) in increments of 1%
A color space where colors are represented by their luminance values only, i e saturation and hue are zero
a strip of standard gray tones ranging from white to black, places at the side of original copy during photography to measure tonal range and contrast obtained
A range of shades of gray in an image Gray scales of scanners are determined by the number of grays, or values between black and white, that they can recognize and reproduce
a reflection or transmission scale of gray tones in steps from clear or white at one end to black at the other, with steps in-between showing evenly intensified series of gray tones (It is attached to the original design or copy to determine accuracy of exposure and uniformity of color separations Patches of yellow, cyan and magenta are included with the scale when photographing for color separations); also referred to as gray or step wedge
Strip of gray values ranging from white to black Used by process camera and scanner operators to calibrate exposure times for film and plates Also called step wedge
A strip of standard gray tones, ranging from white to black, placed at the side of original copy during photography to measure tonal range and contrast (gamma) obtained
A scale showing the full range of gray tones between pure white and solid black While most computer software used today recognizes 256 levels of gray, the human eye can only see 80 to 100 levels
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
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
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)
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
Grayscale "raster" files come in two flavors: 8-bit and 16-bit, where possible value ranges can be from 0 (black) to, respectively, 255 or 65,535 (white)
A file created by scanning a continuous tone original and saving the information as shades of gray; also, an image containing a series of tones stepped from white to black
a color model, which can display up to 256 shades of gray ranging from white to black Grayscale images, especially photographs, are commonly referred to as "black and white "
The range of shades of gray in an image The grayscale of scanners and terminals are determined by the number of shades between black and white that they can recognize and reproduce
An application of black ink (for print) or the color black (for the screen) that simulates a range of tones Grayscale images have no hue (color) In print design, a grayscale graphic image appears to be black, white, and shades of gray, but it only uses a single color ink
GrayScale can be viewed as a degenerate case of PseudoColor, in which the red, green, and blue values in any given colormap entry are equal and thus, produce shades of gray The gray values can be changed dynamically
The tonal range from a very light grey (1% dot) up to solid black (100% dot) in increments of 1% When an image has "shading" or "screening" it is referred to as a grey scale image
