IMAGE BINARIZATION METHOD AND ELECTRONIC DEVICE

An image binarization method and an electronic device are provided. The method includes capturing an image by an image capturing device; selecting a target pixel row arranged at the front from one or more unselected first pixel rows among M pixel rows of the image according to a row order by a binarization circuit; performing, by the binarization circuit, a binarization operation on the target pixel row to obtain a binarized pixel row; storing the binarized pixel row to a main memory by the binarization circuit; performing, by the binarization circuit, the binarization operation to the remaining one or more first pixel rows until M binarized pixel rows are obtained, so as to complete the binarization operation. 本发明有关于一种影像二值化方法与电子装置。所述方法包括经由影像撷取装置撷取影像；根据列顺序，经由二值化电路从所述影像的M个像素列中尚未被选择的一或多个第一像素列选择排列在最前的目标像素列；经由所述二值化电路对所述目标像素列执行二值化操作，以获得二值化像素列；经由所述二值化电路，储存所述二值化像素列至主存储器；经由所述二值化电路对剩余的所述一或多个第一像素列执行所述二值化操作直到获得M个二值化像素列，然后完成对所述影像的二值化操作。
