video camera tube

A film chain usually used a video camera tube as this reduced flicker.

Video camera tubes typically had a certain maximum brightness tolerance.

The size of video camera tubes is simply the overall outside diameter of the glass envelope.

The other half of the light passes to the other side, through a 45-degree angle mirror and into a video camera tube.

Later vidicon and plumbicon video camera tubes produced much cleaner, more accurate pictures.

Early TV cameras (see Video camera tube) did not have a shutter.

The common inch-based sizing system is derived from vacuum image-sensing video camera tubes, which are now obsolete.

A vidicon tube is a video camera tube design in which the target material is a photoconductor.

Philips invented the plumbicon pick up Video camera tube in 1965; almost all of their color cameras used this award winning tube.

Philips invented the Plumbicon pick up Video camera tube in 1965, that gave tube cameras a cleaner picture.

The imaging area of a Four Thirds sensor is equal to that of a video camera tube of 4/3" diameter.

The range of photoemissive devices using caesium include optical character recognition devices, photomultiplier tubes, and video camera tubes.

The new video camera tube developed by Lubszynski, Rodda and McGee in 1934 was dubbed "the super-Emitron".

That is, a special professional video camera that used a video camera tube would be pointed at a Cathode ray tube video monitor.

Although the video camera tube is now technologically obsolete, the size of solid state sensors is still expressed as the equivalent size of a camera tube.

This goes back to the way image sizes of video cameras used until the late 1980s were expressed, referring to the outside diameter of the glass envelope of the video camera tube.

The electronic video camera tube was invented in the 1920s, starting a line of development that eventually resulted in digital cameras, which largely supplanted film cameras around the start of the 21st century.

Early analog sensors were video camera tubes; most currently used are digital charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) active pixel sensors.

In a video camera or digital still camera, the signal is captured with a video camera tube or charge coupled device sensor, which sends the picture to be processed by the camera's electronics.

The video camera tube that evolved from the combined work of Farnsworth, Zworykin and many others was used in all television cameras until the late 20th century, when alternate technologies such as charge-coupled devices started to appear.

In older video cameras, before the mid to late 1980s, a video camera tube or pickup tube was used instead of a charge-coupled device (CCD) for converting an optical image into an electrical signal.

An image dissector, also called a dissector tube, is a video camera tube in which photocathode emissions create an "electron image" which is then scanned to produce an electrical signal representing the visual image.

The image sensor of Four Thirds and MFT is commonly referred to as a 4/3" type or 4/3 type sensor (inch-based sizing system is derived from now obsolete video camera tubes).

In 1926, the Hungarian engineer Kálmán Tihanyi explained in detail that the principle of "storing" electrical charges in proportion to the amount of light received throughout each scanning cycle results in a much more sensitive video camera tube.

In color television and video cameras manufactured before the 1990s, the incoming light was separated by prisms and filters into the three RGB primary colors feeding each color into a separate video camera tube (or pickup tube).
