Abstract
Aspects of the invention include a 3:2 pull down detector coupled to a 3:2 cadence processor and a color edge detector coupled to a binder. The binder may be coupled to a 3:2 cadence processor. A filter, which may be a temporal or infinite impulse response filter, may be coupled to the binder. A selector may also be coupled to the 3:2 cadence processor. A memory and a processor may also be coupled to any of the 3:2 pull down detector, the 3:2 cadence processor, the color edge detector, the binder, the filter and said output selector. The selector may select between a filtered deinterlaced output and a reverse 3:2 pull down output.
Claims22
A method for converting interlaced formatted video to progressive scan video, the method comprising:
- simultaneously performing 3:2 pull down detecting, color edge detecting and temporal filtering on a first field, a second field and a third field;
- binding an output result from said color edge detecting and from said temporal filtering to generate a bound output;
- and
- 3:2 cadence processing said bound output and an output generated from said 3:2 pull down detection.
A machine-readable storage, having stored thereon a computer program having at least one code section for converting interlaced formatted video to progressive scan video, the code sections executable by a machine for causing the machine to perform the steps comprising:
- simultaneously performing 3:2 pull down detecting, color edge detecting and temporal filtering on a first field, a second field and a third field;
- binding an output result from said color edge detecting and from said temporal filtering to generate a bound output;
- and
- 3:2 cadence processing said bound output and an output generated from said 3:2 pull down detection.
A system for converting interlaced formatted video to progressive scan video, the system comprising:
- a 3:2 pull down detector coupled to a 3:2 cadence processor;
- a color edge detector coupled to a binder;
- a filter coupled to said binder, said binder coupled to said 3:2 cadence processor;
- and
- an output selector coupled to said 3:2 cadence processor.
