摘要： An image processing apparatus which enables error diffusion in interlaced-scanning image data. An input unit inputs image data formed by interlaced-scanning, and an adder adds error data to the input data. A binarization circuit performs level-conversion on this data. An error calculator obtains a quantization error as error data to be diffused to other pixels. The error data is stored in first and second lines in a line buffer. When processing for one scanning line is finished, error data for the next scanning line is read out of a frame buffer and stored into the first line in the line buffer, and the error data stored in the second line in the line buffer is stored at a corresponding position in the frame buffer, then the second line is cleared.

摘要： An image processing apparatus prevents an increase in random noise and the like produced by distributing a transformation error, which is produced at the time of a level-number transformation, to unprocessed pixel data. Error data X.sub.n is added to pixel data, which has entered via an input unit, by an adder. Thereafter, the resulting data is subjected to a level-number transformation by a binarizing circuit. Transformation error produced at the time of the level-number transformation is calculated by an error arithmetic unit. The transformation error thus calculated is distributed to unprocessed pixel data by an error-diffusion unit, and the error is accumulated in a line buffer memory as error data. When processing of a prescribed number of lines has ended, a line-number discriminating circuit clears the error data that has been accumulated in the line buffer memory. As a result, an increase in random noise is prevented.

By interpolating the binarization threshold values in units of blocks, the binarization threshold values in units of pixels are calculated, and the multi-valued image is binarized using the binarization threshold values in units of pixels.

摘要： An appropriate binarization threshold can be automatically set between the object density and the background density in a multi-level input image, by determining the frequencies of the luminance levels of the entire image, then calculating the average and deviation of the frequencies, then specifying a region containing the optimum threshold for separating the object and the background in the image, by judging the magnitude of the deviation, and taking the average luminance of the specified region as the binarization threshold. Also in processing an image containing objects of three or more luminance levels, highly precise binarization according to the luminance hierarchy allows exact separation of the image regions, enabling precise character recognition process according to the hierarchic luminance levels.
