摘要:
A weighted median filter interpolator for the interlaced to progressive conversion of video signals is proposed in which for example depending on the available or processable source fields the filter interpolator mode can be set to realize either a three-tap weighted median interpolator or a five-tap weighted median interpolator by respective selection of the weights such that the number of median samples to be processed at a certain time is always an odd number. An increased output quality is achieved if in the case of the five-tap weighted median IPC filter mode a three-dimensional filter aperture is set spreading over a horizontal, a vertical and a temporal dimension of three consecutive fields of an incoming interlaced video signal.
摘要:
The invention relates to an interlaced to progressive conversion method and system by use of an interpolation algorithm (IPC algorithm) which is scaleable with several levels or modes with an increasing computational complexity depending on increasing availability of resources, i.e. computation power, available memory and available memory bandwidth. An IPC mode control can be implemented as a decision table. Peferably, at least five levels of the algorithm can be scaled beginning with line repetition (lowest level), linear interpolation (lower level), median inter-field computation with a three-tap or a five-tap median operator (medium level) and a combination of a linear interpolator and a median interpolator, eventually in combination with edge detection (higher levels of the scaleable algorithm).

摘要:
A piece of seating furniture has a seat plate (1) with a lower seat framework (2) arranged on the underside of said seat plate (1). Also provided is a tilting device (4), by means of which the person sitting on the piece of furniture can execute a tilting movement about a point of rotation located in the seat region. The tilting device (4) is formed by a structural unit which is separate from the seat plate (1) and is arranged on the seat plate (1) of the piece of furniture.
