1. A method of processing video field, the method comprising the following steps:
- detecting a special pattern of each couple among a plurality of couples of adjacent fields distributed respectively to determine a similarity of said each couple of adjacent fields; and
generating a progressive scan television image signal according to a predetermined rule when a predetermined pattern is detected from said similarities of said adjacent fields.

Abstract
A method for the processing of video fields is disclosed. The method includes judging similarities of each couple among a plurality of couples of adjacent fields (wherein each couple of fields includes an odd field and an even field; and generated image signals of another format according to a pattern of the similarities and the original video fields. A method of detecting similarities between odd fields and even fields is further disclosed, such that similarities of adjacent interlaced fields can be utilized to judge the format of image source in order to generate progressive high quality frames more efficiently.

17. A method of detecting similarity between a couple of adjacent fields, wherein the couple of adjacent fields comprises a first field and a second field, the method comprising the following steps:
-
comparing gray levels between a target pixel of the first field and a plurality of adjacent pixels of the second field to determine if a special pattern exists at the target pixel; and
accumulating the special pattern to determine if the first field is similar to the second field. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A device for detecting similarity between couples of fields, the device comprising:
-
a pixel comparator for comparing gray levels between a first target pixel of the first field and a plurality of adjacent pixels of the second field to detect if a special pattern exists in the target pixel; and
an accumulation unit, coupled to the pixel comparator, for accumulating the special pattern to generate an accumulation result; and
a similarity decision unit, coupled to the accumulation unit, for determining whether the first field is similar to the second field according to the accumulation result. - View Dependent Claims (25, 26, 27, 28, 29)
