For an image, the term monochrome is usually taken to mean the same as black and white or, more likely, grayscale, but may also be used to refer to other combinations containing only tones of a single color, such as green-and-white or green-and-black.

One of the system's biggest issues was battery life ; while better than earlier color backlit systems, its 4 hour battery life ( 5 hours on later models ) using 6 alkaline batteries was still not as good as the Game Boy's 10 – 14 hours of four-AA battery lifespan ( due to that system's monochrome screen and lack of a backlight ).

Today, ink monochrome painting still is the art form most closely associated with Zen Buddhism.

Other systems of color photography included that used by Sergei Mikhailovich Prokudin-Gorskii, which involved three separate monochrome exposures (' separation negatives ') of a still scene through red, green, and blue filters.

Previous schemes for color television systems, which were incompatible with existing monochrome receivers, transmitted RGB signals in various ways.

Just as with the other color standards adopted for broadcast usage over the world, SECAM is a standard which permits existing monochrome television receivers predating its introduction to continue to be operated as monochrome televisions.

The electron guns used in monochrome televisions had limited resolution, and if one wanted to retain the resolution of existing monochrome displays, the guns would have to focus on individual dots three times smaller.

Since three separate images were being sent in sequence, if they used existing monochrome radio signaling standards they would have an effective refresh rate of only 20 fields, or 10 frames, a second, well into the region where flicker would become visible.

In order to avoid this, these systems increased the frame rate considerably, making the signal incompatible with existing monochrome standards.

In his system the output of the three camera tubes were re-combined to produce a single " luminance " value that was very similar to a monochrome signal and could be broadcast on the existing VHF frequencies.

The NTSC designers wanted to retain compatibility with existing monochrome TVs.

Sarnoff's tenacity and determination to win the " Color War " pushed his engineers to perfect an all-electronic color television system that used a signal that could be received on existing monochrome sets that prevailed.

* All episodes of this story excluding Episode 1 exist on their original PAL colour master tapes, with the first episode only existing as a monochrome 16mm film print.

Each country, faced with local political, technical, and economic issues, adopted a color television system which was grafted onto an existing monochrome system, using gaps in the video spectrum ( explained below ) to allow color transmission information to fit in the existing channels allotted.

The grafting of the color transmission standards onto existing monochrome systems permitted existing monochrome television receivers predating the change over to color television to continue to be operate as monochrome television.

The CBS color system was scrapped after the FCC embraced the alternative RCA all-electronic dot sequential system, which was fully compatible with the existing monochrome television standard, late in 1953.

The book has been adapted to film three times: a monochrome, British film of the 1950s, a 1952 3-D film titled Bwana Devil, and a 1996 color version called The Ghost and the Darkness, where Val Kilmer played the daring engineer who hunts down the lions of Tsavo.

Spurred on by Crosby's move into TV in the early 1950s, Mullin and Ampex developed a working monochrome videotape recorder by 1950 and a color video recorder by 1954, both created to tape Crosby's TV shows.

The Boy Scout uniform during the 1950s – 1970s continued to have a monochrome light green color for both shirts and shorts or trousers.

A monochrome signal is identical to a color one, with the exception that the elements shown in color in the diagram ( the color burst, and the chrominance signal ) are not present.

The reasons why episodes were produced in colour for monochrome transmission are not stated in any literature but it is possible that it was for the purposes of testing the look of sets and costumes using the new cameras.

A monochrome raster image where the pixel values are to be interpreted as alpha values is known as a matte.

LCD monitors have been adopted by the United States military, instead of CRT displays, because they are smaller, lighter and more efficient, although monochrome plasma displays are also used, notably for the M1 Abrams tank.

Some full color digital images are processed using a variety of techniques to create black and whites, and some manufacturers produce digital cameras that exclusively shoot monochrome.

Branded as " classic television ", these often carry re-runs of programming dating back to the monochrome television era and are promoted as nostalgia.

RGB signal formats are often based on modified versions of the RS-170 and RS-343 standards for monochrome video.

However, PAL and SECAM are just standards for the color sub carrier, used in conjunction with older standards for the base monochrome signals.

The names for these monochrome standards are letters, such as M, B / G, D / K, and L. See CCIR, OIRT and FCC ( the standardization bodies ).

When he sheds his immortal existence, he experiences life for the first time: he bleeds, sees colors for the first time ( the movie up to this point is filmed in a sepia-toned monochrome, except for brief moments when the angels are not present or looking ), tastes food and drinks coffee.

For some inkjet printers, monochrome ink sets are available either from the printer manufacturer or from third-party suppliers.

Nearly all his paintings were in fresco, very large in scale, and often in chiaroscuro or monochrome ; and are remarkable for rapidity of execution and a certain mannered style.

The names black-and-white, B & W, monochrome or monochromatic are often used for this concept, but may also designate any images that have only one sample per pixel, such as grayscale images.

The figures are presented as busts against a monochrome background which in some instances is decorated.

Color values are commonly stored in 1-bit binary ( monochrome ), 4-bit palettized, 8-bit palettized, 16-bit highcolor and 24-bit truecolor formats.

EGA can drive an MDA monitor by a special setting of switches on the board ; only 640 × 350 high-resolution monochrome graphics and the standard MDA text mode are available in this mode.

Legacy Analog TVs, whether color or monochrome, use continuous voltage signals which do not have a fixed number of different intensities, although the signals are subject to noise introduced in transmission.

The Palm Zire and Palm Zire 21 are inexpensive and are differentiated from the rest of Palm's line by having monochrome screens without backlighting, having only two quickbuttons instead of four, and a traditional up / down navigation button instead of a 5-Way Navigator, though both of these entry-level models are lightweight ( 3. 8oz or 108g ), sporting a white front with a matté gray plastic back.

The monitors are often black-and-white monochrome and have the scanning reversed to compensate for the reflection of the mirror.
