There are a large number of applications for various types of cameras. However, we will be discussing video cameras as well as document cameras.
Document cameras are also famous by the name visual presenters, visualizers (in UK), docucams or digital overheads. They are primarily used to display video or images in real-time and require a connection with a laptop or PC in order to be used. This is especially used in order to show a big audience something in real-time, in contrast to something being pre-recorded. The document camera has the ability to project and magnify images of a three-dimensional object, along with transparencies.
In short, they are extremely high resolution displaying webcams, mounted on “arms” that act as a tripod. This makes it easy to angle the camera in order to show a piece of paper on the table or display a three-dimensional item to the audience.
In theory, all objects may be on the display with the use of a document camera. The camera is able to produce a live picture with the use of a projector or monitor. Various document camera/visualizer have different levels of flexibility when it comes to the placement of objects.
For example, if there is a large working area, a ceiling mounted document camera may be more handy and useful. Users may place large objects in the frame of the camera and can rotate as per use.
Below are the various applications of video cameras in modern times:
- Used in lectures or classrooms to demonstrate experiments or share various ideas so they can be better understood using visual media
- Used in conferences, training sessions, and meetings to communicate ideas or material easily
- In video conferences to ensure the presence of important meeting members in case they are not able to make it in person
- In courtrooms, to make a witness present if they are too far away to attend in person
- Used in various medical equipment such as displaying x-rays or telemedicine, or colonoscopy procedures
Modern video cameras have numerous designs and use.
- Professional video cameras are used in television studios, production of television shows
- Electronic field production cameras have three separate sensors responsible for recording each color, e.g. red, blue, and green. In addition to this, these cameras offer manual controls that allow fine-tuning to the point of rendering automated camera operations useless.
- Camcorders have combined the use of a camera and VCR and other older recording devices in a single body. These are more frequently using in the production of various live television shows, home movies, to gather electronic news and other many everyday applications. They are able to rotate a complete 360° in order to capture the entire scene effectively.
- Video cameras have been embedded and built-in to various modern devices such as tablets and smartphones. This has made sharing information very convenient and rapid because they are easily available to everyone who can afford one. Smartphone companies are actively working on improving the camera quality in each generation of smartphones they produce.
