What is 16 4 4

Image format

The image format describes the aspect ratio of film recordings or television screens. It is usually specified as width: height. For a long time, 4: 3 was the standard format for televisions and TV programs. Since movies for the wide screens are more likely to be filmed in 16: 9 or even 21: 9, black bars appear on the top and bottom when played on 4: 3 televisions. As a result, the overall TV picture is much smaller and fewer details can be seen. In the 90s the 16: 9 aspect ratio became more and more popular in television. This was and is primarily due to the fact that the development of LCD and plasma televisions made it possible to produce lighter and more compact models with a larger screen. This is accompanied by the change from television at home to home cinema, which should bring the viewer as close as possible to the action.

Advantages and disadvantages of different image formats

Different image formats each have their own advantages and disadvantages. The 4: 3 format is well suited for depicting people and faces. The rather elongated shapes can make optimal use of the height of the screen. In the 16: 9 format, however, individuals quickly appear lost on the wide area. In addition, their overall share in the picture decreases. For landscapes and their representation, however, the widescreen is much more suitable. It corresponds somewhat more to the natural field of vision of humans, which has a ratio of around 3: 2. Viewers can see the TV picture in 4: 3 format at a glance, but their eyes have to be moved for information at the top and bottom of the picture. It is also not possible to focus on both areas at the same time. The 16: 9 format does not have this disadvantage. The right and left edges are not in focus here, but they are rarely used for important elements. People also instinctively perceive movements in the corner of their eyes better than those at the top or bottom.

Black bars due to the aspect ratio

If a film or TV signal is recorded in a different picture format than the television set, black stripes often appear on the screen. When playing 16: 9 or 21: 9 on a 4: 3 television, the upper and lower edges of the screen are displayed in black because this is the only way to transmit the signal in its full width. The same thing happens when a 16: 9 television plays 21: 9 films. In the TV settings, however, it is often possible to adjust the display.
