Title: Binarization system
Inventor: KOSHIRO KUNIO
IPC: H04N1/40
Filed: 1984-09-26
Abstract: PURPOSE:To apply binarization correctly to a picture of an optional object even with uneven lighting nby dividing the entire picture into rectangular partial regions and obtaining an optimum threshold value giving a ratio of black picture element number to white picture element number in coincidence with the ratio of black region to white region of a test pattern at each rectangualar partial region. CONSTITUTION:A binarization circuit reads the content of a memory 8 storing a threshold value Zkh at each partial region of the test pattern by using an address generating cirlcuit 7 to recognizes the Zkh. A comparison circuit 10 compares the Zkh with a value of all picture elements belonging to the partial region Qkh, outputs logical 1 when the value of picture element is larger than the threshold value and outputs 0 when smaller than the threshold value. An accumulation circuit 9 inputs a data 0 or 1 from the comparator circuit 10 and accumulates the value to a register Rkh corresponding to each partial region Qkh. Since the value of the picture element is compared with the threshold value Zkh at each partial region, the accumulation is executed at each register Rkh. It is possible to read the content of the register Rkh in the accumulation circuit 9 from an operating device.
