Abstract
A method and apparatus for converting an image in an image processing system are provided, in which if a plurality of low-definition video frames are used for converting a low-definition picture to a high-definition picture, a weight is determined for each of the plurality of low-definition video frames, and one of two image fields that form a high-definition video frame is generated using the plurality of low-definition video frames according to the weights of the plurality of low-definition video frames.
Claims19
A method for converting an image in an image processing system, comprising:
- determining to convert a low-definition picture obtained from a source picture to a high-definition picture using a plurality of low-definition video frames of the low-definition picture, based on whether an image characteristic of the source picture is similar to an image characteristic of a high-definition picture or an image characteristic of a low-definition picture;
- determining weights for the plurality of low-definition video frames;
- and
- generating one of two image fields that form a high-definition video frame of the high-definition video picture using the plurality of low-definition video frames according to the weights of the plurality of low-definition video frames.

An image conversion apparatus in an image processing system, comprising:
- a controller configured to determine to convert a low-definition picture obtained from a source picture to a high-definition picture using a plurality of low-definition video frames of the low-definition picture, based on whether an image characteristic of the source picture is similar to an image characteristic of a high-definition picture or an image characteristic of a low-definition picture, and determine weights for the plurality of low-definition video frames;
- and
- a converter configured to generate one of two image fields that form a high-definition video frame of the high-definition video picture using the plurality of low-definition video frames according to the weights of the plurality of low-definition video frames.
A method for converting an image in an image processing system, comprising:
- first generating a top field and a bottom field that form a high-definition picture, using a single low-definition video frame, if the high-definition picture is to be generated using the single low-definition video frame;
- second generating comprising generating the top field of the high-definition picture using a preceding low-definition video frame between two consecutive low-definition video frames and generating the bottom field of the high-definition picture using the two consecutive low-definition video frames, if the high-definition picture is to be generated using the two consecutive low-definition video frames without applying weights to the two consecutive low-definition video frames;
- and
- third generating comprising generating the top field of the high-definition picture using the preceding low-definition video frame between the two consecutive low-definition video frames and generating the bottom field of the high-definition picture by applying the weights to the two consecutive low-definition video frames, if the high-definition picture is to be generated using the two consecutive low-definition video frames according to the weights for the two consecutive low-definition video frames.
