Embodiment Construction

[0027] A method is provided which is implemented in a video image processing device included in a video signal path. An example of such a video signal path is in the figure 1 shown in . The video signal path is an abstract schematic. It can be implemented on one or more discrete signal processing devices. In the example shown there are three components, namely video decoder 1 , video feature processor 2 and video output processor 3 . An alternative could be a so-called system on a chip. The video signal path is included in, for example, a television set 4 (see figure 2 )middle. Alternative video image processing systems in which the present invention may be implemented include video monitors, video recorders, DVD players, and set-top boxes.

[0028] back to figure 1 , the video decoder 1 receives a composite video signal 5 from an IF (intermediate frequency) stage or a baseband input such as a SCART. The video decoder 1 will detect signal properties like PAL, NTSC and...

Abstract

A video image processing method comprising: receiving a video signal (5, 6) carrying input information indicative of a moving image occupying a display area (12); processing the received input information, and generating a video signal carrying input information indicative of occupation of the display area (12); An output video signal (10, 11) of output information of a moving image of an area (12); characterized in that a selected portion (17, 18) occupying this display area (12) represented by said input information is rescaled ) portion of the moving image independently of the other portions of the moving image occupying the remainder of the display area (12).

Description

technical field [0001] The invention relates to a video image processing method, comprising: receiving a video signal carrying input information representing a moving image occupying a display area, and processing the received input information and generating a video signal carrying input information representing a moving image occupying the display area The output video signal of the output information. [0002] In particular, the invention relates to a video image processing system which is particularly suitable for carrying out this method. [0003] The invention also relates to a display device, such as a television set, which is particularly suitable for carrying out the method. [0004] The invention also relates to a computer program product. Background technique [0005] An example of a method and an image processing system of the above-mentioned type is known from the abstract of JP 2002-044590. This publication relates to a DVD (Digital Versatile Disc) video rep...
