Method and device for conversion of television image of a non-limitative way to the progressive format of the format and their applications.

摘要

The invention relates to a method and a device for the conversion of a digital image source of television of the interlaced format to the progressive format. & br / the digital image source formed of two frames t1, t2 is cut (a) in the groups of n under - frequency bands. A filtering (b) a high (hf) and low frequency (lf) of the bands of frequencies is carried out so as to discriminate between a signal of the spatial information (lf) and time (hf) representative of the structure of the evolution of the structure of the digital image source in the time interval between - frame. A recomposition (c) of the frequency spectrum of the digital image source is carried out by the frequency processing, by spectral composition of the contribution of the evolution of the structure of the image in order to generate a frequency spectrum recomposed. A progressive format image is constructed (d) from the frequency spectrum recomposed in the field of image or frequency. & br / application to the production of digital television images to the progressive format and to the estimation of movement between images.
