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： When saturation conversion is done by multiplying data by a saturation conversion parameter with a constant value regardless of image features, an image which can give good impression to the user cannot always be obtained.In this invention, an image is segmented into a predetermined number of blocks, and attributes are discriminated in units of blocks. Conversion characteristics are calculated on the basis of saturation conversion parameters of an image, which are set in correspondence with the discrimination result, and saturation is converted based on the calculated characteristics. In this way, appropriate saturation correction can be achieved in correspondence with the image attribute.

摘要： A photographing environmental light spectral distribution detector acquires spectral distribution data of photographing environmental light upon photographing an object image, and an observation environmental light spectral distribution data detector acquires those of environmental light used upon observing a reproduced image. A signal processor converts an image signal photographed by a camera under the photographing environmental light in accordance with the spectral distribution data of respective types of environmental light, generates colorimetric data that an output unit can output, and outputs the colorimetric data to the output unit, thus accurately reproducing the original color of the object while the object is placed under the observation environmental light.

摘要： In a system for converting an input image signal input from an image input device into an output image signal to be output by an image output device, an image compression unit converts a spectral image input via an image input unit into R, G, and B data, obtains principal component data by making principal component analysis of the spectral image, and stores these data in an input image storage unit. When the principal component data and R, G, and B data are loaded and stored in an output image storage unit, a spectral reflectance reconstruction unit reconstructs the spectral reflectance of each pixel using these data. A printer model determines the dot quantities of inks used to record each pixel in an image output device on the basis of the calculated spectral reflectance, and generates an output image signal for the image output device. In this way, image data which allows to estimate the spectral reflectance characteristics of an input image is provided, and faithful color reproduction can be realized.
