Abstract
A motion blur correction device includes a motion blur correction section which performs motion blur correction processing on an intended video data, and a correction intensity judgment section which instructs the motion blur correction section to cancel the execution of the motion blur correction processing when the frame rate of the video data is equal to or less than a predetermined value. As a result, motion blur correction is prevented from being automatically performed when motion blur correction is not required.
Claims10
A motion blur correction device that performs motion blur correction on video data, comprising:
- a judgment section which judges a necessity for motion blur correction based on a frame rate of the video data;
- and
- a motion blur correction section which performs motion blur correction processing on the video data used as a judgment object according to details of a judgment result by the judgment section;
- wherein the judgment section judges that the motion blur correction processing is not necessary to be performed on the video data used as the judgment object, when the frame rate of the video data is equal to or less than a predetermined value;
- and
- wherein the motion blur correction section cancels execution of the motion blur correction processing on the video data used as the judgment object, when the judgment section judges that the motion blur correction processing is not necessary to be performed.
