Appl. No.:

10/446330

Inventors:

Steve Selby - Scarborough, CA
Peter Dean Swartz - San Jose CA, US

Assignee:

Genesis Microchip Inc. - Alviso CA

International Classification:

H04N 7/01

US Classification:

348459, 348441, 348443

Abstract:

A video display system is disclosed. The video display system comprises a display generator for providing a display timing signal and a frame rate converter for receiving input video data, input video timing, and for providing output video data. The system includes a control logic for receiving a frame rate indication signal, the video input timing and the display timing signal. The control logic changes the display frame rate of the display generator in accordance with the native frame rate of the program, and in such a way as to maintain a stable image throughout.

Peter D. Swartz - San Jose CA, US

Assignee:

Genesis Microchip Inc. - Santa Clara CA

International Classification:

H04N 7/01
H04N 5/46

US Classification:

348554, 348441, 348448, 348452

Abstract:

A multi-function display controller that includes a source detector unit for determining if the source of an input stream is either film originated source originated or video source originated. A source converter unit for converting the input image stream to a common signal processing format is coupled to the source detector unit. Once converted to the common signal processing format, a determination is made if the input image stream is interlaced or non-interlaced (progressive scan). If the input image stream is interlaced, a de-interlace unit converts the interlaced signal to progressive scan using either motion adaptive or motion compensated de-interlacing techniques. It should be noted that in the described embodiment, motion vectors generated for use by the motion compensated de-interlace can be optionally stored in a memory unit for use in subsequent operations, such as motion compensated frame rate conversion or noise reduction (if any).

International Classification:

H04N 7/01

US Classification:

348452

Abstract:

Global-adaptive deinterlacing systems and methods for reducing scintillation and feathering artifacts. Motion adaptive deinterlacing (MADI) local motion quantization thresholds are adaptively adjusted according to the amount of global motion present in the video sequence, thereby minimizing scintillation and feathering artifacts when deinterlacing the fields. A set of global motion scenarios are defined for the purpose of classifying fields, and a number of global motion indicators are used to detect on a field-by-field basis different global motion scenarios.
