In addition, as the same algorithm is used for background correction and elimination of lamp noise, the background corrected signals show a much better signal-to-noise ratio compared to the uncorrected signals, which is also in contrast to LS AAS.

* High contrast ratio ( over 15, 000: 1 ), excellent color, fairly wide color range ( gamut ) and low black level.

Details about encryption, key management, and logging are all discussed in the specification as are the minimum specifications for the projectors employed including the color gamut, the contrast ratio and the brightness of the image.

Some LCD monitors using this technology have a feature called " Dynamic Contrast " where the backlight is dimmed to the brightest color that appears on the screen, allowing the 1000: 1 contrast ratio of the LCD panel to be scaled to different light intensities, resulting in the " 30000: 1 " contrast ratios seen in the advertising on some of these monitors.

LCD displays that use this implementation will usually have the ability to dim the LEDs in the dark areas of the image being displayed, effectively increasing the contrast ratio of the display.

When it comes to contrast ratio, AMOLED display still performs best due to its underlying technology, where the black levels are displayed as pitch black and not as dark gray.

The screen also had Nokia's Clearblack layer, improving the contrast ratio and bringing it closer to that of the AMOLED screens.

* Brightness and contrast ratio: Contrast ratio is the ratio of the brightness of a full-on pixel to a full-off pixel and, as such, would be directly tied to brightness if not for the invention of the blinking backlight ( or burst dimming ).

In any case, there are two large caveats to contrast ratio as a measure of LCD performance.

The second caveat is that the human eye can only image a contrast ratio of a maximum of about 200: 1.

The teaching is Socratic, typically with small classes, and often boasts a lower student-to-teacher ratio than at large universities ; professors teaching classes are allowed to concentrate more on their teaching responsibilities than primary research professors or graduate student teaching assistants, in contrast to the instruction common in universities.

In contrast to submachine guns and autocannons, machine guns ( like rifles ) tend to share the characteristic of a very high ratio of barrel length to caliber ( a long barrel for a small caliber ); indeed, a true machine gun is essentially a fully automatic rifle, and often the primary criterion for a machine gun as opposed to an automatic rifle is the presence of a quick-change barrel or other cooling system ( see below ).

In contrast to most eukaryotic cells, mature sperm cells largely use protamines to package their genomic DNA, most likely to achieve an even higher packaging ratio.

Also the pixel resolution, contrast ratio, refresh rate, and color gamut of an LCD preview screen cannot compete with the clarity and shadow detail of a direct-viewed optical SLR viewfinder.

Related measures are the " contrast ratio " and the " contrast-to-noise ratio ".

Windows Media Player features universal brightness, contrast, saturation and hue adjustments and pixel aspect ratio for supported video formats.

Slower scans provide a better signal-to-noise ratio, resulting in better contrast and higher resolution.

Given this inherent distortion, it is not unusual for a television or video projector to truthfully claim a linear contrast ratio ( difference between darkest and brightest output levels ) of 1000: 1 or greater, equivalent to 10 bits of audio precision even though it may only accept signals with 8-bit precision and use an LCD panel that only represents 6 or 7 bits per channel.

In contrast to the Atlantic slave trade where the male-female ratio was 2: 1 or 3: 1, the Arab slave trade usually had a higher female: male ratio instead, suggesting a general preference for female slaves.

In contrast, AMD enjoyed a remarkably smooth process transition and had ample supplies available, causing Athlon sales to become quite strong.

By contrast, if the same historian had made the same claim five times in five different places ( and no other types of evidence were available ), the claim is much weaker because it originates from a single source.

By contrast, a person who had been acquitted of a lesser offence could not be tried for an aggravated form even if new evidence became available.

Similarly, release print stocks usually are available only in two varieties: a " normal " print or a deluxe print ( on more-costly print film like Kodak Vision Premiere ) with slightly greater saturation and contrast.

In contrast, the reloading of shotshells that are usually not available in low-cost, promotional pricings, such as. 410 bore, 16 ga, 20 ga., and 28 ga., becomes more economical to reload in much smaller quantities, perhaps within only 3-5 boxes of shotshells per year.

Quasi-judicial institutions, by contrast, make rulings on cases, but these rulings are not in themselves legally binding ; the main example is the individual complaints mechanisms available under the various UN human rights treaties.

A huge selection of microscopy techniques are available to increase contrast or label a sample.

In contrast, an MUA using IMAP displays messages directly from the server, although a download option for archive purposes is usually also available.

Greater latitude was given to managers of state-owned factories, while capital was made available to them through a reformed banking system and through fiscal policies ( in contrast to the fiscal anarchy and fall in revenue experienced by the Soviet government during perestroika ).

However, the colors are less brilliant and are available in a restricted range in contrast to soft pastels.

Pie menus show available options, in contrast to invisible mouse gestures.

In a consumer protection approach, in contrast, it is acknowledged that individuals may not have the time or knowledge to make informed choices, or may not have reasonable alternatives available.

By contrast, elastic applications can take advantage of however much or little bandwidth is available.

The term shareware is used in contrast to retail software, which refers to commercial software available only with the purchase of a license which may not be copied for others ; public domain software, which refers to software not copyright protected ; open-source software, in which the source code is available for anyone to inspect and alter ; and freeware, which refers to copyrighted software for which the developers solicit no payment ( though they may request donations ).

Huxley was particularly fond of the shop and the large variety of products available there, ( in stark contrast to the much smaller selection in English chemist's shops ).

In contrast, the competing CDMA2000 system uses one or more available 1. 25 MHz channels for each direction of communication.

In contrast, Raymond claims that an inordinate amount of time and energy must be spent hunting for bugs in the Cathedral model, since the working version of the code is available only to a few developers.

The machine had vastly more application functionality, including a number of built-in application programs, an easy to use database, a diary and an alarm clock and featured end-user programmability in the form of the successful Organiser Programming Language ( OPL ), a BASIC-like language which was compiled to intermediate code, in contrast to the interpreters which were commonly available for other consumer computers of the time.

Boyle supported the policy that the Bible should be available in the vernacular language of the people ( in contrast to the Latin-only policy of the Roman Catholic Church at the time ).

In contrast, a hostile bidder will only have more limited, publicly-available information about the target company available, rendering the bidder vulnerable to hidden risks regarding the target company's finances.

In contrast to this, the same period in history marked a massive suburban expansion available primarily to whites of both wealthy and working-class backgrounds, facilitated through highway construction and the availability of federally subsidized home mortgages ( VA, FHA, HOLC ).

Many techniques are available which modify the light path to generate an improved contrast image from a sample.

In contrast to simply increasing the maximum power level covered by the scale, Carl Sagan suggested adding another dimension: the information available to the civilization.
