摘要:
From profiles of an input color space and an output color space, the specific color data on respective color spaces are obtained, and a color space compression parameter is set based on each specific color data obtained. In other words, the color space compression parameter for appropriately converting data within the input color space into data within the output color space is derived from each specific color data. The color space compression processing (color matching) is performed on an absolute color space using the derived color space compression parameter so that it becomes possible to perform at a higher speed an appropriate color matching that takes into account the characteristics of the input color space and the output color space.
摘要:
The gray axis of an input apparatus is shifted so as to match the gray axis of an output apparatus. Each data on a plane of equal lightness located in the Gamut of the input apparatus is shifted in the same direction in accordance with the shift of the gray axis by an amount of shifting smaller in proportion to greater distance from the gray axis. Therefore, the image is not governed by the chromaticness in the shifting direction even if the gray axis is shifted. Points located outside the Gamut of the output apparatus is compressed-converted into points within the Gamut (surface) where color difference is minimized while maintaining the lightness. A desired image is reproduced without inversion in the lightness after Gamut compression between data.

First image data is obtained by performing an image capturing operation with a flash and, subsequently, second image data is obtained by performing an image capturing operation without a flash. By using data of a differential image between the first and second image data and a relative spectral distribution of flash light, the spectrum reflectivity in a position on a subject corresponding to each pixel is obtained and object-color component data is acquired as data from which an influence of an illumination environment has been removed. On the other hand, illuminant component data indicative of spectral distributions of a plurality of illumination light are prepared. By combining arbitrary illuminant component data to the obtained object-color component data, an image with a different illumination environment can be reproduced.

摘要:
The present invention provides a technique capable of promptly and easily acquiring object color component data of a plurality of subjects even if the spectral distribution of light illuminating said plurality of subjects is not known in advance. For example, under predetermined conditions of irradiating a subject with predetermined illumination light by using an electronic flash, an image input system captures an image of a first subject to thereby acquire first color image data. On the basis of the acquired first color image data, the image input system estimates first object color component data of the first subject. After that, the image input system captures an image of the first subject in unknown illumination environments to thereby acquire second color image data. By using the first object color component data and the second color image data, the image input system estimates the spectral distribution of unknown illumination. Subsequently, on the basis of the estimated spectral distribution of unknown illumination, the image input system calculates a conversion matrix for converting color image data of the subject acquired in the unknown illumination environments into object color component data.

A digital camera is provided with an optical filter unit 43 which is movable in the slide direction SL in front of the CCD 41, and infrared light emitters 25 and 32 for emitting near-infrared light. The optical filter 43 has an infrared cut filter 45 for cutting light in the infrared range, and a visible light cut filter for selectively transmitting light of the infrared range by cutting light in the visible light range. While maintaining the identicalness of the main object, the infrared cut filter 45 is disposed above the CCD 41 to acquire visible light image data via the CCD 41, and the object is irradiated with infrared light emitted from the infrared emitters 25 and 32, and the visible light cut filter is disposed above the CCD 41 to acquire infrared image data, i.e., non-visible light image data, by the CCD 41. As a result, a visible light image and a non-visible light image are easily acquired of the same object.
