Abstract
A video image deinterlacing apparatus includes intrafield and interfield processors therein. The intrafield processor is responsive to field data (e.g., sequence of video image fields) depicting a time-varying video image. The intrafield processor is configured to determine edge and edge steepness characteristics for a plurality of omitted pixels within fields of the time-varying video image. The interfield processor, which is also responsive to the field data, is configured to identify pixels possessing time-invariant properties.
Claims12
A video image deinterlacing apparatus, comprising:
- an intrafield processor responsive to field data depicting a time-varying video image, said intrafield processor configured to determine edge and edge steepness characteristics for a plurality of omitted pixels within a first field of the time-varying video image;
- and
- an interfield processor responsive to the field data, said interfield processor configured to identify pixels within the first field possessing time-invariant properties;
- wherein said intrafield processor is configured to determine edge and edge steepness characteristics for an omitted pixel within the first field by determining first differences between a plurality of pixel values for pixels within the first field located along a first line extending across the omitted pixel at a first angle and determining a sum of the first differences using a first slope variation calculator;
- and
- wherein said intrafield processor is further configured to determine edge and edge steepness characteristics for the omitted pixel within the first field by determining second differences between a plurality of pixel values for pixels within the first field located along a second line extending across the first field at a second angle orthogonal to the first angle and determining a sum of the second differences using a second slope variation calculator.
