Abstract
A video processing device for converting an interlaced signal into a progressive signal includes an OSD mixer which mixes an OSD display, such as a caption or a telop, with the interlaced signal, a cinema detector which detects a pulldown pattern by comparing video images of different fields, a phase comparator which compares a timing of change in the OSD display and a timing of change in a cinema video image based on OSD mixing signals indicating OSD-mixed locations in the OSD mixer and on the pulldown pattern detected in the cinema detector, and an interpolated pixel generator which generates a new pixel between lines of the interlaced signal by an interpolation method based on a detection result in the cinema detector and on a comparison result in the phase comparator.
Claims6
A video processing device for converting an interlaced signal into a progressive signal, comprising:
- an OSD mixer configured to mix an OSD display with the interlaced signal;
- a cinema detector configured to detect a pulldown pattern by comparing video images of different fields;
- a phase comparator configured to compare a timing of change in the OSD display and a timing of change in a cinema video image based on an OSD mixing signal indicating an OSD-mixed location in the OSD mixer and on the pulldown pattern detected in the cinema detector;
- and
- an interpolated pixel generator configured to generate a new pixel between lines of the interlaced signal by an interpolation method based on a detection result in the cinema detector and on a comparison result in the phase comparator.
