Image-processing apparatus, image-capturing apparatus, image-processing method and image-processing program

Abstract

An image processing apparatus (100) for converting photographed image data representing a scene luminance into visual image data representing a visual image, comprises a data analyzing section (52) to obtain a viewing condition to view a visual image, to analyze the photographed image data, and to obtain an image converting condition and a viewing condition parameter for a color management employing a color appearance model on the basis of the analysis result of the photographed image data and the viewing condition for the visual image; an image converting section (53) to convert the photographed image data on the basis of the image converting condition obtained by the data analyzing section so as to produce the visual image data; and a formatting section (54) to attach the viewing condition parameter to the visual image data produced by the image converting section and to output the visual image data attached with the viewing condition parameter. The invention does not need executing special measuring and otherwise the special knowledge is not needed, and the image data which can be adopted to the colorful external mode can easily generated from the shooting data.

Description

technical field [0001] The present invention relates to an image processing device for processing image data, a photographing device including the image processing device, an image processing method, and an image processing program. Background technique [0002] Today, scanned images of color photographic films or digital image data photographed by photographing devices are distributed via storage devices such as CD-R (CD-Recordable, CD-Recordable), floppy disks, memory cards, and the Internet, or in Displayed on display devices such as CRT (cathode ray tube, Cathode RayTube), liquid crystal, plasma, etc., and small liquid crystal monitors of mobile phones, or using output devices such as digital printers, inkjet printers, and thermal printers , are printed as hard copy images, etc., the display and printing methods are becoming more and more diversified. [0003] However, various display and printing devices have different color gamuts and grayscale characteristics due to ...

Problems solved by technology

[0017] In this way, it is difficult to add appropriate observation condition parameters to image data, and it is almost impossible to calculate appropriate observation condition parameters for those who do not have special knowledge about color appearance models.
