Panning detection circuit
专利汇可以提供Panning detection circuit专利检索，专利查询，专利分析的服务。并且PURPOSE: To detect the movement of the entire pattern accurately with high detection accuracy by detecting it as the movement of the entire pattern due to panning and camera shake only when almost the edge of the entire pattern is a moving portion.
CONSTITUTION: A moving detection section 11 detecting a moving part of a picture signal from a difference between frames of the inputted picture signal of the interlace scanning and an edge detection section 12 detecting a picture edge part of a picture signal from the difference in the unit of blocks in the field of the picture signal or in the unit of picture elements, a moving edge count means 13 counting the part detected by both the detection sections 11, 12 simultaneously, a static edge count means 16 counting the part detected by the edge detection section 12 only and a discrimination detection section 20 detecting the movement of the entire pattern when the count of the moving edge count means 13 is large are provided to the circuit. Thus, the detection accuracy is improved in comparison with the case of detecting the moving part of the entire pattern from the quantity of the detected number.
