Picture Quality For Dummies

0
Filed under Audio Video

You can easily see with your own eyes the difference between good and poor picture quality. However, the technical definitions of image quality are rather complicated: image quality is a mix of contrast ratio, color saturation, accuracy and resolution.

Contrast ratio is the ratio between the brightest and darkest color a HDTV can produce. The better your system is, the higher contrast ratio it can produce. If your system has low contrast ratio, you will experience dull and washed out images, and fine details will be lost. The good news is that there were great improvements in contrast ratio, and even cheap HDTVs have enjoyable contrast ratios at this time.

Black levels are also very important for good picture quality. Good black levels mean you see absolute blacks, not greyish blacks. Poor black levels can be especially annoying in dim light conditions, because this is when your eyes are very sensitive about blacks. Lot of people achieve absolute black by setting the black levels too low: by doing this you may have absolute blacks, but black shadow details will be lost. Another important aspect of picture quality are the high white levels.

High white levels make the images on the screen appear vivid and lively. This makes the viewing more pleasant. Again, lot of people make a mistake by setting the white levels too high: this way certain details and bright highlights can be lost.

Important characteristics of the images on your display are color temperature, saturation and accuracy. 6500K, corresponding to daytime illumination, is the standard for color temperature. This is the natural light temperature. Everything above this is bluish, and everything below is yellow or reddish. If the color temperature is not set properly, every color will be bluish or reddish.

Color saturation can be relatively easily adjusted by using the color patterns that come with calibrations discs or TV channels. Color accuracy depends on how your HDTV decodes the image data. These are pretty complicated issues. You may want to read more about this elsewhere, but if you only want to stay at beginner-level, it is enough for you to know that the decoders of your system should match the color encoding used in film production.

Greyscale and display characteristic also affect the color reproduction of your HDTV, but again this is above the beginners knowledge about image calibration. You can choose to learn about this, or you can hire a specialist to do it for you.

The latest HD resolutions provide 5 times more pixel amount compared to Standard Definition. As a result, image is not simply clearer, but there is night and day difference: the smallest detail can be noticed on the image. If you want to have the best, go for 1080 capable HDTVs.

The term of percieved sharpness relates to resolution. It means users can sharpen artificially the image without modifying the resolution by creating a crisp edge along the border of the image. This also gives the impression of better image quality.

Strange New Years Resolution

The worst thing about coming back into work after the Christmas break is that you hit reality. During the Christmas break I was getting up at 11 every single day so getting into work for the first time in just under 2 weeks for 8.30 has not been an easy thing to do. Have you made any New Year’s resolutions at all this year? My personal one this year is a bit of decorating and I have to say I do not usually bother. People who are fat are trying to cut back chocolate and go to the gym and people are doing crazy things like eat a different fish everyday of January.

One of the major questions that needs to be asked here is do resolutions stay in place or do people just drop them? It has to be said that most people with resolutions will drop them within January and I have a fact to back this one up. Are there not more and more obese people in Britain and the USA every year? This is the proof and it is quite disappointing that people cannot cut back a little bit on the fatty foods and head over to the gym for a minimal amount of time a week!

I received a very nice 46” LED television for Christmas along with a stand and thought to myself, this looks a bit out of place in my room. Well I say it was a gift, the most part of it was bought by myself as a Christmas present to me. So with this new TV in place I decided to decorate my room. This was then turned into a big New Year’s resolution by my girlfriend so I thought well I may as well keep it as my personal resolution.

So my mission for January is to get in some great looking bedroom furniture tear out my old white bedroom furniture and look for some brand new white wardrobes. It does sound like something I am going to struggle with!

What Kind of TVs Does Hitache Produce?

Even though you can still get a Hitachi projection television, this company is now developing and marketing the front projection television models which incorporate digital light processing as the procedure for transmitting the picture.  Hitachi is one of a few manufacturers that are moving towards more slender televisions to meet the demands of the public.

Projection television sets are available in rear and front projection versions.  They are still an intelligent choice for consumers who will be shopping for jumbo screen, high definition televisions as they remain more affordable than the flat screen LCD televisions, in spite of the fact that flat screen televisions have become less expensive in recent years.  The Hitachi projection television is sold as a home theater system and features digital light processing as the means by which the photo is sent to the screen. 

Most televisions manufactured recently offer digital processing due to the fact that signals are quickly switching from analog to digital.  Digital signals are more efficient and can offer consumers a better picture.  If you currently subscribe to cable or satellite television, you may have already experienced the difference in television reception provided by digital signals. 

When you choose your new Hitachi projection television, you may then decide from among several sizes that feature digital light processing technology.  This allows a small picture that is received from the video signal to be expanded to the size of the TV.  Hitachi markets several versions of a front projection television, with screens that range between 52 and 72 inches wide.  Needless to say, the expense of each model is decided primarily by the size of the screen. 

Digital light processing televisions provide high quality projections and are routinely considered a technological advancement compared to the LCD projection.  The reason why consumers overwhelmingly favor the LCD televisions is these televisions are flat. Although the Hitachi projection television is still too bulky to hang on your wall, it is significantly less bulky than older big screen televisions.  In addition, a DLP television is substantially more reasonably priced than the flat screen, LCD television with a comparably sized screen.  Because usually people do not have a television attached to their wall –as LCD flat screens are made to do - it does not matter to the majority of consumers whether the television is extremely slender, as long as it offers state of the art picture and sound. 

While there remain a few Hitachi projection televisions available which employ CRT technology which produces a heavier unit, the primary focus for the Hitachi projection television industry is concerned with front projection.  Hitachi is currently one of the major manufacturers who are working with 3D television technology which will easily adapt to front projection digital technology and might be offered to customers soon.

TV Viewing Distance and Screen Placement in the Home Theater

Filed under Computers

The optimal television screen size is directly correlated with the available viewing distance.  Conversely, there are other aspects as well that must be taken into account.

Viewing Distance: Is it just an affair of individual partiality?

Sit extremely near your big screen TV and you would be able to discern the image build-up structure - scanning lines or pixels forming the picture, consequently off-putting your attention and ruining your home theater experience. Nonetheless, stay excessively far away, and the impression will be gone.

The truth is that there are no scientific rules here. This doesn’t mean that there aren’t any principles that you need to adhere to when planning a huge screen purchase or a probable home theater room.

SMPTE Recommendations and the THX Certification standards:

The Society of Motion Pictures and Television Engineers (SMPTE) commends that the screen dimension for home theater use needs to fill a 30 degrees field of view - in the horizontal map - for the spectators. On the other hand, the perfect television viewing distance ought to be such that the screen width fills an angle of 30 degrees from the watching place.

This SMPTE principle is also similar to the THX certification guidelines in that these advise that the back line of seats has to have no less than a 26 degrees watching angle and while suggesting an optimum viewing angle of 36 degrees.

So How Does All This Translate In Practical Terms?

An overall rule for the TV watching distance based on the SMPTE and visual perception guidelines, is that the nearest TV watching distance between you and your big screen television should be limited to almost two times the screen width (more accurate 1.87 x screen width for a subtended angle of 30 degrees), while the farthest distance being barely five times the width of your screen.

On the contrary, it is also critical to comprehend that these maximum and minimum watching distances have to be seen in the light of the video signal definition.

A fully resolved HD television (1080i, 1920×1080) supports a nearer viewing distance than ordinary analog TV. While twofold the screen width will be the best television watching distance for a HDTV display, it will be a bit too close for typical TV; in the later case, a three times the screen width will be a superior pick.

When it speaking about the use of regular-size standard definition analog TVs in the home theater, i.e. around 36 / 40 diagonal, the most favorable watching distance range is between 8 feet and 12 feet. television sets tinier than 36-inches aren’t big enough to meet the requirements for Home Theater use as their smaller screen dimension would not impart the wanted impact on the watcher.

Vertical Angle of View & Screen Height:

For best possible viewing, the sight of the watcher needs to be leveled with the center of the screen.

Maximum vertical angle of view: In those home theater set-ups where this is not likely, the SMPTE principles advise that the maximum vertical angle quantified at the seated eye height from the front row center location to the top most section of the projected image should not surpass 35 degrees.

This does not stand for the best possible watching angle but rather the threshold beyond which the watcher would be exposed to an intensified neck strain.

Minimum angle of vision: While there do not appear to be any specialized SMPTE or THX guidelines in this respect, studies have presented that if the screen dimension occupies less than 15 degrees of the viewer’s vertical field of view, then that picture looks miniature.

Practical Points:

In a usual home theater set-up, you do not need to actually fret concerning neither the maximum vertical angle of view, nor concerning the tiniest vertical angle of vision for an effective movie theater experience.

If one were to adhere to the mentioned TV viewing distance of twofold the screen width (as additionally listed previously according to the SMPTE principle of 30 degrees horizontal field of vision), you would necessarily be obeying the smallest possible angle of vision. The grounds behind that is there is a preset relation between screen height and width in accordance to your home theater screen aspect ratio of either 16:9 or 4:3.

Keeping in mind that most home theater rooms are almost 10 feet (3m) high, the resulting vertical viewing angle is customary well within the maximum of 35 degrees detailed in the SMPTE principles, all you must do is solely remain within the double the screen width guideline for your viewing distance.

TV brackets are the MTV generation

There's an interesting thing that happens when you get a new TV. Realsing when you get home, that yes, there's no where to put it. You fudge the measuring process, you sort of think "yeaaaaaahhh it will fit in that corner" and set your eyes on the biggest screen your budget can afford.

Getting that it home is exciting, just make sure you have something to put it on or hang it from. Have something to hang it from, have something to put attach it to, otherwise you'll have a big stupid television rather than a big clever one.

TV stands are a good way to go if you’re putting the TV in your living room. They're best suited to a room that doesn't have enough wall space to justify a TV bracket. TV stands can be quite expensive, so shop around and get a good deal. Minimalistic simplistic. That is the best route to take.

Of course if you do have enough room to put your TV on the wall, this is a good route to take. In fact, buy yourself a TV for every wall in your house and slowly degenerate your existence into the MTV cribs era that it should be. On the subject of MTV cribs, did you know the homes used are rarely the homes of the said celebrity? Surely this is a front page scandal of huge significance? Maybe not…

If you haven't got a TV on every wall of the house, then you're no one. Everyone knows that right? You need a TV in the bathroom and one in the kitchen, a TV that pops up from the end of the bed, and a TV in the fridge. Oh and the garage of course, never forget the garage. And probably a few in your car. That about settles it doesn't it?
