Abstract
PURPOSE: To perform the recognition for the character and pattern through one reading action by memorizing the same picture into the picture memory in the form of the plural number of binary-coded picture information featuring different slice levels and then selecting the picture memory for recognition.
CONSTITUTION: Same picture 3 is applied to level slicer 4 and then delivers the picture signals which is binary-coded by different slice levels. And the binary-coded signals are memorized in picture memories 5-1, 5-2 and 5-3 each. Furthermore, the contents of these memories are selected by switching unit 6 to be supplied to feature extracting circuit 7, and picture signals extracted through circuit 7 are recognized by decision circuit 8. In case the recognition is impossible, unit 6 is controlled by the control signals and via redecision control circuit 9. Thus the recognition is possible by the different slice levels memorized in other memories 5-1, 5-2 and 5-3 each. As a result, the recognition can be given assuredly for the character and pattern just through one reading action.
