摘要： There is provided an image processing apparatus which handles an image as a digital signal, comprising: an input device to input image data indicative of a concentration of an image; a binarization circuit to binarize the input image data; a positive/negative state detection circuit to detect whether error data generated when the image data is binarized by the binarization circuit is in a positive state or a negative state; and a selector to select whether the error data generated upon binarization is to be corrected or not, on the basis of the positive or negative state of the error data. The input device has a generator to read an original and generate an analog image signal and a converter to convert the analog image signal into the digital image data. The error data is the difference between the input image data and the binary data produced by the binarization circuit. With this apparatus, an image of a good picture quality can be obtained by improving the error diffusion method as a halftone processing method. Even when portions of high and low concentrations in an original are very close to each other, the blanking phenomenon, wherein no dot is printed in the low concentration area near the boundary between those portions, and the consequent problem that the reproduced image lacks its proper content can be prevented.

摘要： If the size of an error portion within an image of the frame of interest is equal to or larger than a threshold and it is determined that no error portion exists within an image of a frame immediately before the frame of interest, a display unit (115) is caused to display the image of the frame immediately before the frame of interest as the image of the frame of interest. If the size of an error portion within the image of the frame of interest is smaller than the threshold and it is determined that an error portion exists within the image of the frame immediately before the frame of interest, the display unit (115) is caused to display a result obtained by correcting the error portion within the image of the frame of interest using a pixel group surrounding the error portion.
