Document Type and Number:
Japanese Patent JP6834417
Kind Code:
B2
Abstract:
An image processing apparatus includes a controller configured to control an image scanner to generate scanned data by scanning an image recorded on a document sheet, calculate an edge intensity of each of pixels included in the scanned data, determine a binarization threshold from pixel values of particular pixels, the particular pixels being a part of the pixels included in the scanned data, each particular pixel having a density value higher than density values of surrounding pixels thereof and having an edge intensity equal to or higher than an edge threshold, and generate a binary image from the scanned data, using the binarization threshold.
