The most recognizable camera in the world

The history of Polaroid began in 1922 at the Mouven Summer Camp for Boys, which was located on a lake in Connecticut. Barney Griden worked as a mentor in the camp, he was passionate about physics and later patented eight inventions for scuba diving.

Barney demonstrated scientific experiments to teenagers, woke them in the middle of the night to show a thunderstorm and explain its nature. Seen experiments so influenced his students that in the future many of them took up science.

The most famous among those students was Edwin Land, he patented 535 inventions – only Thomas Edison received more patents. Land’s inventions include a polarizer, an X-ray film, 3D films, night vision devices for the army, and much more. The scientist led the development of the U2 spy plane when he was an adviser to U.S. President Dwight Continue reading

Standard Definition Video Recording Formats

First of all, it should be noted that, without exception, all modern digital video cameras use certain compression algorithms and compression of the original video, and the “recording format” just characterizes the compression algorithms used. Let’s see what recording formats are found today in standard-resolution digital video cameras; we will talk about high-resolution video cameras separately, a little later.

DV is a video format with frame-by-frame compression (compression), that is, each frame of the video is compressed individually. At the same time, the compression ratio can be variable within the same frame — areas of the image that are difficult to compress are compressed with a lower compression ratio, and simple ones with a larger one. In this case, the total compression ratio for the entire frame remains constant (5: 1). The resulting stream for video is approximately 25 Mbps. The DV frame size is fixed and is (for the PAL standard) 720×576 pixels. This format is used in miniDV camcorders, and video recording, respectively, is performed on miniDV cassettes.

It is not necessary to be afraid of robbers, a sudden fire can also make significant adjustments to the layout of the room and to your budget. Or maybe you want to look after a small child – and for this, too, there is no point in buying expensive equipment, a fairly small Internet camera.
