Techniques for distinguishing a pulldown field sequence from a normal field sequence are disclosed. According to one aspect of the techniques, the method for detecting pulldown field sequence comprises receiving a field sequence, combining two adjacent fields into one frame, detecting whether the combined frame has a combing phenomenon, if there is such a combing phenomenon, and determining a number of how many times the combing phenomenon occurs continuously in the combined frame. Based on the number, it can be determined whether the field sequence is a normal field sequence or a pulldown field sequence.
