The multiple-camera setup, multiple-camera mode of production, multi-camera or simply multicam is a method of filmmaking, television production and video production. Several cameras—either film or professional video cameras —are employed on the set and simultaneously record or broadcast a scene.
Digital room correction may involve minimum phase algorithms, to maintain wavefront coherence over the intended frequency range.. The use of analog filters, such as equalizers, to normalize the frequency response of a playback system has a long history; however, analog filters are very limited in their ability to correct the distortion found in many rooms.
These vision engineers had two roles. Firstly, they set up the CCUs at the start of a production and ensured that the picture created was of broadcast quality. This process included a lengthy alignment process in which the vision engineer would work with the camera operator, to adjust the settings on both the actual camera and the CCU in tandem ...
Pitch correction is an electronic effects unit or audio software that changes the intonation (highness or lowness in pitch) of an audio signal so that all pitches will be notes from the equally tempered system (i.e., like the pitches on a piano).
Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. [1] [2] Most hi-fi equipment uses relatively simple filters to make bass and treble adjustments. Graphic and parametric ...
In that case, not only local tone mapping but also dynamic range adjustment can be effective in revealing detail throughout light and dark areas: The principle is the same as that of dodging and burning (using different lengths of exposures in different areas when making a photographic print) in the chemical darkroom. The principle is also ...
An adaptive equalizer is an equalizer that automatically adapts to time-varying properties of the communication channel. [1] It is frequently used with coherent modulations such as phase-shift keying, mitigating the effects of multipath propagation and Doppler spreading. Adaptive equalizers are a subclass of adaptive filters.
C ij = {(camera i,camera j):P'(camera i, XY i) ∩ P'(camera j, XY j) ≠ {}) So there is a set of camera vector pairs C ij for which the intersection of the inverse projections of two points XY i and XY j is a non-empty, hopefully small, set centering on a theoretical stationary point xyz.
