	Grayscale - Wikipedia, the free encyclopedia
		Grayscale images are distinct from fl-and-white images, which in the context of computer imaging are images with only two colors, fl and white; grayscale images have many shades of gray in between.
		Grayscale images are often the result of measuring the intensity of light at each pixel in a single band of the electromagnetic spectrum (e.g.
		Grayscale images intended for visual display are typically stored with 8 bits per sampled pixel, which allows 256 intensities (i.e., shades of gray) to be recorded, typically on a non-linear scale.

	Grayscale
		A grayscale image is recorded by the MX camera’s sensor, which has a given pixel resolution, for example the MX40’s 2352 x 1768 which is more than 4 million pixels.
		Other cameras use grayscale only to determine where the edge of a marker is, which is a far simpler task – all the grayscale information from pixels that are deemed not to be edges is thrown away.
		Not only do the MX cameras use all the grayscale information available, the algorithm used is also extremely accurate and able to determine the center of a marker to 1/50th of a sensor pixel.

	Grayscale (Site not responding. Last check: 2007-10-10)
		Grayscaling in Nevron controls is controlled on two levels — global (or control) level and per object level which acts on individual objects such as lights, lines and fill effects.
		This line of code will turn on grayscaling and if you do not touch the grayscale related properties of the other objects in the scene (lines, fill effects etc.) the whole scene will be rendered in gray scale.
		Depending on the object it is applied to grayscaling works in a different way — for example if a texture fill effect is rendered in grayscale mode the associated OpenGL texture RGB values are converted, which essentially means that the whole texture is recreated.

	Glossary - Grayscale Images (Site not responding. Last check: 2007-10-10)
		A grayscale (or graylevel) image is simply one in which the only colors are shades of gray.
		In fact a `gray' color is one in which the red, green and blue components all have equal intensity in RGB space, and so it is only necessary to specify a single intensity value for each pixel, as opposed to the three intensities needed to specify each pixel in a full color image.
		Grayscale images are very common, in part because much of today's display and image capture hardware can only support 8-bit images.

	5.5 Conversion to Grayscale (Site not responding. Last check: 2007-10-10)
		Of the three methods for converting an image to grayscale, this one produces the flattest (that is, with the least contrast) and the darkest conversion.
		The value component is a conversion to grayscale that is based on moving to the neutral axis by selecting the maximum RGB component.
		This grayscale is clearly the brightest of the three, which makes sense because the value is defined as the maximum of the R, G, and B components (see Figure 5.6).

	Line art vs. grayscale
		Grayscale mode must be used to preserve any intermediate tones in the images.
		Grayscale mode with 256 tones is intended for pictorial images, not text, and we're used to text being sharper.
		Grayscale consumes 8 times more memory than Line art, and if Grayscale is used, then we are back to our original tune, about how scanning at more than about 100 to 150 dpi is wasted effort, because the printers halftones cannot reproduce more than this.

	What is grayscale? - a definition from Whatis.com - see also: 8-bit grayscale, 16-bit grayscale (Site not responding. Last check: 2007-10-10)
		For every pixel in a red-green-blue (RGB) grayscale image, R = G = B. The lightness of the gray is directly proportional to the number representing the brightness levels of the primary colors.
		As with 8-bit grayscale, the lightness of the gray is directly proportional to the number representing the brightness levels of the primary colors.
		In analog practice, grayscale imaging is sometimes called "fl and white," but technically this is a misnomer.

	Grayscale calibration
		Grayscale is the result of all three video channels within a display device having the correct gain and bias settings such that an accurate display gray from fl to white can be produced at or near 6500K.
		In a nutshell, calibrating a TV's for accurate grayscale helps ensure that fl images are as close to fl as possible and white images are as close to white as possible without the intrusion of unwanted colors.
		Lastly, by calibrating the grayscale, it allows the CRTs (or LCD or DLP or Plasma), to operate closer to the optimal levels where their luminance is as close to D65 or 6500 Kelvin, thus prolonging operating life.

		Setting display grayscale properly is important because image colors will only be produced accurately when grayscale is correct.
		Grayscale is the result of all three video channels within a display device having the correct gain setting and linearity such that a standard scale of gray is produced from fl to white.
		The setting of grayscale is the adjustment of the individual "brightness" and "contrast" setting for each of the three video channels, namely R, G, and B. Controls for each of the independent color channels have different names even though the function is similar.

		To grayscale is to convert a continuous-tone image, like a fl-and-white photograph, to an image made up of pixels.
		Grayscaling is different from dithering, which uses either fl or white pixels next to one another to simulate shades of gray.
		In grayscaling, each individual pixel can be a different shade of gray.

	Grayscale Image Scanning
		Grayscale images present the best opportunity for basic image enhancement.
		In a grayscale image each pixel represents one of 256 brightness levels with 0 being the least bright, (fl) and 255 being the brightest, (white).

	Olympus Microscopy Resource Center: Digital Image Processing - Grayscale Image Complement - Interactive Java Tutorial
		Grayscale image complement operations are useful for enhancing the visibility of subtle brightness variations among gray levels in regions of a digital image where fine details are obscured.
		Due to the logarithmic response of the human eye to illumination level differences, subtle brightness variations among the gray levels in bright regions of an image may be difficult to detect.
		Performing a full complement operation on a grayscale digital image reverses the brightness range of the image and produces the equivalent of a photographic negative, which can improve the visibility of gray-level variations in bright regions.

	Keohi HDTV - ISF - Michael TLV - MTLV Grayscale Report (Original Version)
		The grayscale graph is a gross simplification of the grayscale calibration process and the science behind what is being done.
		And often times, a client will misinterpret these same grayscale graphs and conclude that his TV was so closely tracking grayscale out of the box than he did not really need to hire you in the first place.
		Although this is nowhere near as colourful as the typical grayscale tracking chart found in magazines, it is easy to use and far more accurate in terms of telling the client just how different his pre-calibration grayscale was compared to the post calibration grayscale.

		The fg_graydcb() function applies a grayscale transform to a direct color bitmap, so it can only be used when a high color or true color virtual buffer is active.
		The first fg_graydcb() parameter is the name of the array containing the direct color bitmap to be transformed, and the second parameter is the name of the array that will receive the transformed direct color bitmap (these two parameters can be the same array).
		The fg_grayvb() function applies a grayscale transform to a rectangular region of the active virtual buffer.

		The terms "Grayscale" and "Black and White" are often used interchangeably, but they are not identical.
		The first problem that you're likely to run into when working with many grayscale photographs is discoloration or "yellowing" of the image.
		Most of the methods are overkill, in that they take too much time and make too many changes to the original when there is only one goal in mind: creating a true Grayscale image with no yellowing.

		Well, if a designer were to scan a grayscale image as a bitmap, he/she would note that they had lost all detail which was not either fl or white.
		Conversely, if they were to scan a bitmap image as grayscale, they would notice that the fl and white edges are not sharp and would have soft bits of gray around them.
