Abstract
PURPOSE:To obtain plural linear light positions on a TV screen in a real time by removing an unnecessary linear light by the use of a prescribed evaluation function and executing a weighted operation. CONSTITUTION:When a brightness (V) is below a threshold again, the value of the evaluation function value S(=SIGMAV) is inputted to N comparators 22. In the respective comparators 22, the comparison of the area of a peak Si (1<=i<=N) obtained previously in the same line is executed. Then, the number of '0' (S<Si) of an output (1 bit) from the respective comparators 22 is counted by an ordinal number decision circuit 28. The output of this circuit 28 is the ordinal number K corresponding to the area of the peak. Further, the ordinal numbers Ki and K obtained in the past are compared in a comparator 24. Then, at the time of K<=i<N-1, Ki is increased by 1 and at the time of K<N and Ki= N-1, data such as Ki, Si of register groups 26 is respectively replaced by data such as K, S.
