    摘要： By smoothing a full-color image, staircasing of characters even in a gradation image is removed. An area to be smoothed is detected from image data having a plurality of color components, and image data included in the detected area is smoothed in units of color components.Image data which places an importance on resolution is smoothed by increasing the resolution to reproduce smooth characters and figures. Image data which places an importance on gradation characteristic is output without increasing the resolution, thus attaining high-gradation recording. A character or figure is detected from bitmap image data input from external equipment, and is smoothed. In correspondence with the density of the smoothed image data, the pulse width is switched, thereby changing the resolution of image data.

    摘要： In order to produce a high-quality output of an image which is a mixture of images having different characteristics, there is provided an image processing apparatus having an image memory storing an entered color image and a feature detector, arranged for detecting a feature signal from the entered color image and storing the feature signal in the image memory. The feature signal represents a feature of the entered color image. An outputter is arranged for reading an image signal of the entered color image and the feature signal thereof out of the image memory, and outputting the image and feature signals as a recording signal. Processors are arranged for respectively processing one of a number of color components, which represent color image information, in accordance with the recording signal. The detection and storage in the image memory of feature signals and the readout of the image signal and associated feature signal from the image memory are performed in parallel.

    摘要： An image processing apparatus is provided that is capable, in case of forming a color image based on color image data entered from an external device, of improving the print quality by smoothing the contour of the printed character or pattern. In consideration of the reproducibility of the printer, a character or a fine line not exceeding a predetermined density is printed with a lowered resolving power. Also the reproduced density is selected between the average of the interpolating density or the original density. As a result, in case of outputting a multi-value image composed of a character or a pattern giving emphasis on the resolving power, the multi-value smoothing interpolation can be executed according to the density of the character, thereby smoothing the contour of such character or pattern and improving the print quality.

    摘要： An image processing apparatus and method are adapted to prevent a decline in image quality while reducing the number of bits in a discrimination signal stored in memory. The apparatus includes an image compressing device for encoding image data in prescribed block units and then storing the encoded data in a memory, after which the stored image data is decoded and outputted. A black-character discriminating unit discriminates a plurality of attributes of the image data, and a black-character compressing device encodes the plural results of discrimination in conformity with the image processing. The plurality of codes are divided into blocks of different sizes in such a manner that resolution is reduced, and the codes are stored in memory. Thereafter, the stored codes are decompressed and sent to a masking UCR circuit and to a spatial filter. On the basis of the codes sent, the masking UCR circuit and spatial filter apply image processing to the image data outputted from the image compressing device.
