Preferably, the incompatibility detection processing detects an incompatible part incompatible with the first image processing from the image constituent parts.
Abstract:
The present invention relates to a digital television, and more particularly, to an apparatus for detecting a common frame in an interlaced image. Since it is determined exactly whether interlaced scanning format fields neighboring in view of time belong to the common frame or different frames, it can be determined more exactly to detect 3:2 pull-down and 2:2 pull-down so that deinterlacing image quality of film mode image is improved.
Abstract:
Nowadays, continuous media data processing is performed more and more by programmable components, rather than dedicated single-function components. To handle such data appropriately, a system must guarantee sufficient system resources for processing. The method according to the invention proposes scalable motion compensated up-conversion of the frame rate of video sequences. By computing suitable quality measures for the algorithms (404) that perform the up-conversion (402), the method according to the invention allows to predict the required resources given an input video (406). Furthermore, the visual quality of the output video sequence is predicted. Based upon these predictions, the method selects the best algorithm to perform the up-conversion thereby allowing an optimal resource utilization of the system, for example a programmable platform for media processing.
Abstract:
A significant change of scene in a gradually changing scene is detected with the aid of at least one camera means (2) for capturing digital images of the scene. A current image (4) of the scene is formed together with a present weighted reference image (6) which is formed from a plurality of previous images (8) of the scene. Cell data is established based on the current image (4) and the present weighted reference image (6). The cell data is statistically analysed so as to be able to identify at least one difference corresponding to a significant change of scene. When identified, an indication of such significant change of scene is provided.

Abstract:
A system and process for adding a photorealistic rendering of a body of water to a virtual 3D scene or image and creating a video therefrom having interactive water effects. A region of water is added to an image by adding an area depicting the original scene as it would appear if reflected by still body of water. Then, the appearance of the added water region is distorted over a series of image frames in such a way as to simulate how the reflected scene would look if the surface of the water were in motion. The water can have dynamic waves and the user can interact with the water in numbers of ways, including generating ripples on the water surface and creating rain. In addition, these effects can be achieved at full screen resolution with the use of the latest graphics hardware by employing a texture shifting technique.

Abstract:
Method of modifying data for obtaining a scalable video signal composed of a base video signal and a set of enhancement video signals from a non-scalable video signal, in a cost-effective manner. Said method comprises: a set of attenuation steps applied to coefficients composing said non-scalable video signal, said attenuation steps being assembled in cascaded or in series for delivering said base video signal, a re-encoding step associated with each one of said attenuation steps for delivering one of said enhancement video signals, from the coding error generated in each attenuation step. The scalable video signal is directly generated from said coded video signal and expensive processing steps such as motion compensation and motion estimation performed in prior-art methods are thus no longer needed. The number of enhancement video signals can be easily increased by assembling, in cascade or in series, other attenuation and re-encoding steps.
