    • PURPOSE:To attain extraction of a retrieved item and efficient edition processing by segmenting a character region, a photographic region, a table region and a diagram region mixed in a picture automatically and deciding by which attribute of the character, picture and diagram each region is constituted automatically. CONSTITUTION:The black picture element of one line data of an inputted picture signal is counted by an accumulation circuit 2, a decision circuit 3a, a differentiation circuit 6a, a decision circuit 3b eliminate noises or a white line to detect the 1st region. The output signal (g) is given to a shift register circuit 4 via a gate circuit 5 to accumulate black picture elements in the sub-scanning direction and a decision circuit 3c, a differentiation circuit 6b and a decision circuit 3d extract the 2nd region. The a count value ri is inputted to an accumulation circuit 2c and a decision circuit 3e decides a photographic region. Further, a counter circuit 7 counts the run length of white picture elements, stores the result in a memory circuit 8, a counter circuit 9 counts the number of generated elements to obtain the mean value of the white run length and a decision circuit 3f decides whether the region is a character or a diagram.
