摘要: Disclosed is a device and method for recognizing characters in an image. An input part receives the A blurring decision classifies received image into character blocks background blocks, calculates average energy ratio of compares with predetermined threshold to determine whether blurred. If not blurred, binarization pixels pixel threshold, binarizes brightness value based on comparison, pixel. recognition recognizes binarized
