Videos Cameras Definition
The videos cameras it’s generally a portable device that allows images and sounds can records. It converting them into electrical signals that can be reproduced by a specific device.
In the beginning, camcorders used electronic tubes as sensors and, very different from what’s start today.
They were composed of thermionic valves that allowed images to form with the lens system by scanning by an electron beam.
In the 1980s, interconnected charging devices stood developed enabled a considerable reduction in the weight and size of videos cameras and a higher quality of image and sound.
The operational process of camcorders begins with the decomposition of light between three components (red, green, and blue) using a prism of dichroic mirrors.
On the other side of the lens are the pickups, which reconstruct the image and forward it to the preamplifier circuits.
The image continues its journey to processors that are responsible for correcting various parameters.
And once the painting is ready, they record and broadcast to the production system, that is, to the network of devices that make up the work environment.
1. TV cameras
- In the case of TV cameras, two main types can have recognized as portable, associated with the signal recording system, and studio, which works integrated into a production system.

- And with extremely low resolutions and several frames per second; on the other hand, many of these models did not include a microphone.
- About the first limitation, likely, the Internet connection speed cap available at that time.
- As well as its instability outweighed the lack of technology to improve performance.
- Such devices became more sophisticated in no time, offering options.
- And the level of quality that a few years earlier can take remains unimaginable.
- However, the Web spread to mobile phones, causing the most significant social impact of the last decade, forcing manufacturers to incorporate as many functions into their products as possible.
- And also the camcorder one of the smartphone’s essential components.
- As it allows us to video conference, take photos, and capture videos.
- And interact in innovative ways with applications and games, and even read Quick Response codes to access content instantly online.
- Although the quality of traditional cameras is much higher than that offered by the mobile phone.
- And many professionals carry both types of devices with them.
- Since it’s not always necessary to take the perfect capture but to do it quickly and comfortably.
