Abstract
An edge adaptive de-interlacing apparatus and method are disclosed. The edge adaptive de-interlacing apparatus includes a complexity detection module, a qualifier, a comparator and a mixer. The complexity detection module detects complexity associated with a target pixel. The qualifier is coupled to the complexity detection module for generating similarity of at least one possible edge angle in response to the complexity. The comparator is coupled to the qualifier for comparing the similarity of the at least one possible edge to select a preferred edge angle. The mixer is coupled to the comparator for generating pixel data of the target pixel according to the preferred edge angle.
Claims12
An edge adaptive de-interlacing apparatus for de-interlacing a target pixel, comprising:
- an extreme-value detection module, for detecting at least an extreme-value position of a luminance distribution curve in a first region associated with the target pixel to output a prediction signal for indicating a predicted angle region;
- a qualifier, coupled to the extreme-value detection module for generating similarity of at least one possible edge angle in response to the predicted angle region;
- a comparator, coupled to the qualifier for comparing the similarity of the at least one possible edge angle to select a preferred edge angle;
- and
- a mixer, coupled to the comparator for generating pixel data of the target pixel according to the preferred edge angle.
An edge adaptive de-interlacing method for de-interlacing a target pixel, comprising:
- detecting at least one extreme-value position surrounding the target pixel and accordingly outputting a prediction signal for indicating a predicted angle region;
- generating similarity of at least one possible edge angle in response to the predicted angle region;
- selecting a preferred edge angle according to the similarity of the at least one possible edge angle;
- and
- generating pixel data of the target pixel according to the preferred edge angle.
