PURPOSE:To prevent an error of the check result of an ununiform picture to be checked by allowing a picture processor which finds the number of pictures to be checked and the total area to find cumulative sum data on a small area consisting of picture elements gradually. CONSTITUTION:Time-series picture data dij obtained by a two-dimentional scan is inputted to the 1st shift register 13 of M picture elements by (n) lines to be delayed successively, and each line output is extracted selectively; and sum data Si,j on (n) picture elements is found gradually from picture data, selected line output data, and data stored in the 2nd register in M-stage constitution, and stored successively in the 2nd shift register 16. The cumulative sum data is found gradually from data stored in a cumulative sum register 23, the input sum data to the shift register 16, and selected tap output data si-m,j of the 2nd shift register 16, and then stored in the cumulative sum register 23 to obtain the cumulative sum data on (m)X(n) picture elements. |
