    摘要： An image processing apparatus such as a digital printer or digital facsimile apparatus for half tone processing input image data has: an input device to input image data indicative of a concentration of an image; a discriminating circuit to discriminate whether the input image data is smaller than a threshold value or not; a binarizing circuit to binarize the input image data into binary data of high and low levels; and a setting circuit to set the binary output of the image data to the low (0) level irrespective of the result of the binarization by the binarizing circuit when the input image data is determined to be smaller than the threshold value. The input device includes a reading circuit to read the original image and a generator to generate image data indicative of the original image concentration. When the pixel concentration to be processed by an error diffusion method is smaller than the threshold value, the error data generated for that pixel is set to 0, with the result that particles-like noises in the high contrast portion are eliminated and the encoding efficiency in highlight portions is improved. Thus, a high quality image of excellent resolution and gradations can be transmitted at a high speed.

    摘要： According to the present invention, when image data are subjected to quantization processing using an error diffusion method, the generation of a striped pattern which is a cause for deterioration of picture quality in the error diffusion method is prevented. In the present invention, an original image is read and image data are generated. The image data obtained by reading the original image are quantized using an error diffusion method, and the quantized image data can be output and recorded by a thermal-head printer.Furthermore, according to the present invention, an error between the density of an input image and the density of an output image after being subjected to a quantization processing using an error diffusion method is perfectly preserved. In an image processing appartus for performing a quantization by dispersing an error between input image data and output image data which arises when the input image data are quantized, to image data of surrounding picture elements, the error between the input image data and the output image data is computed otherwise determined, the error is subjected to a predetermined weighting processing, the error subjected to the weighting processing is dispersed to surrounding picture elements, and a surplus of the error generated in the weighting processing is corrected.
