    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: A PDL interpreter rasterizes image data, which are described in page description language, entered from a host computer, and stores the rasterized image data in an image memory. A CPU discriminates the type of image, pixel by pixel, by referring to the image data stored in the image memory, and stores a discrimination code, which indicates the result of discrimination, in a code memory. The CPU reads out image data that have been stored in the image memory and reads the discrimination code corresponding to these image data out of the code memory. The image data read out of the image memory are subjected to different binarizing processing by two binarizing circuits. Depending upon the discrimination code read out of the code memory, a selector selects the output of one of the two binarizing circuits and sends the selected image data to a printer. Accordingly, it is possible to obtain a high-quality image which is a mixture of images having different characteristics, such as an image containing character or line drawings, continuous grayscale images, etc.
