Description
Technical Field
The invention relates to a broadcast-level camera, in particular to a modular broadcast-level high-definition camera, and belongs to the technical field of camera shooting.
Background
The basic working principle of the camera is as follows: converting the optical image signal into an electrical signal for collection, editing, storage or transmission; when a user shoots an object with a camera, light reflected from an external scene and the object is collected by a camera lens, focused on a light receiving surface of an imaging device (for example, a target surface of an imaging chip) through an optical path system, and converted into electrical signals with different magnitudes through a semiconductor imaging device, so that a so-called "video signal" is obtained. Because the light-electric signal obtained by the photosensitive chip is very weak, firstly, the electric signal is amplified by the pre-amplifying circuit, and then processed and adjusted by various circuits, so that the obtained standard 'video' signal is sent to recording media such as recording or storage media to be reserved, or is broadcast by a transmission system, or is sent to a monitor to display the image.
Cameras are generally classified in the industry into three general categories, namely broadcast, professional and home.
The broadcast-level camera is mainly applied to the field of professional broadcast television, has high image quality, comprehensive performance and various special adjustable functions, but is expensive and large in size.

In order to improve performance indexes, an image pickup device having a large size is generally used. Therefore, they have the highest sharpness, the highest signal-to-noise ratio and the best image quality. Of course, the volume is large, and the price is not acceptable to the ordinary people.
2) The news interview (ENG) camera, because the operational environment of this kind of camera is special, this kind of machine is small, light in weight, portable, has good adaptability to the non-standard illumination condition, has higher safety and stability in adverse circumstances (such as the change on a large scale of operating temperature), has characteristics such as debugging convenience, degree of automation are high, control flexibility, convenient to carry, its image quality is slightly lower than camera for the studio, the price is also relatively cheap.
3) The working condition of the EFP camera is between the two cameras, and the performance index also takes the two aspects into consideration. Their image quality is similar to that of studio cameras, but their size is smaller, and they can meet the demand of portable on-site program production.
In summary, the existing broadcast-level cameras, especially the broadcast-level high-definition cameras, have high expertise, excellent image quality and relatively high price.
