Image processing device

摘要

The present invention provides an image processing device that converts an interlace image signal into a progressive signal so as not to cause degradation of image quality in edge parts of letters or the like, when performing an IP conversion with respect to an image that is mixed with an OSD such as a caption and a telop. The image processing device includes: an OSD mix part that mixes an on-screen display with an input interlace image signal; a motion detecting part that detects a motion by comparing pixel data between different fields; and an interpolation pixel generating part that generates a new pixel between lines of the interlace image signal by interpolating calculation with an interpolation method that depends on an OSD mix ratio of the OSD mix part and a result of the motion detection by the motion detecting part.
