Title:
画像処理装置、画像処理方法、およびプログラム
Document Type and Number:
Japanese Patent JP5960010
Kind Code:
B2
Abstract:
An image processing device may include an image scanning unit; an image memory; a sample area designating unit; a binarization unit for implementing a filtering process on a scanned multi-valued image, to produce the compensated image data and for binarizing the compensated image data; a correlation operation unit for acquiring each of the correlations between the binary image data and the scanned multi-valued image data; and an optimal binarization information selecting unit for selecting the optimal parameter value or binary image data based on the correlations. The binarization unit may include a parameter value setting section, a filtering process section, and a binarization process section for binarizing each of the compensated image data based on a predetermined binary threshold.
