Title: Binarization circuit device
Inventor: KANEKO TETSUAKI
IPC: G06T5/00
Filed: 1985-09-20
Abstract: PURPOSE:To precisely and properly binarize a picture signal at low contrast by dividing a picture in a certain section into picture element signals at plural slice levels and obtaining a binarization slice level in accordance with the number of divided picture elements. CONSTITUTION:The picture signal 1 is binarized by fixed binarization circuits 2-4 at thresholds 1a-1c, and each output is stored as digital quantity in termporary storage circuits 5-7 for each picture element unit in the specified read section. Then counting circuits 8-10 counts memory signals for each picture element unit and output signals corresponding to the counted number. A threshold calculating circuit 11 multiplies the outputs 8a-10a of the circuits 8-10 by multipliers 13 and 14. An adder 15 adds the result and a reference signal 17 to generate a floating threshold signal 16. For instance, if the signal 1 is smaller than the value 1a, the output of the counting circuit comes to zero from 10a, whereby the signal 16 turns out to be a value obtained by adding DELTAV2 to the signal 17. When the value 1b is smaller, the outputs 9a and 10a come to zero, therefore the signals 16 and 17 approximately become equal. A picture signal binarization circuit 12 binarizes the signal 1 with the aid of the signal 16.
