(effect of execution mode)
In the execution mode of above explanation, can obtain various effects.
(1) in camera head, the RAW data that image processing part is taken the photograph body with the quilt of being taken by image pickup part are the basis, generate the image according to sRGB.Then, be recorded in the colour gamut in client's catalogue and be the standard colour gamut (AdobeRGB etc.) beyond the sRGB, generate the image that is suitable for each colour gamut most for comprising at least.
And, when video generation device is connected to image-reproducing means through image output device, in above-mentioned client's catalogue, record the reproduction color gamut information that extracts from the intrinsic information preservation portion of image-reproducing means.And,, can will reproduce color gamut information through manual input and be registered in client's catalogue not obtaining when reproducing color gamut information from image-reproducing means.Thus, can generate the image of the colour gamut of the image display device that is suitable for the user most.
(2) the reproduction color gamut information of reading from the intrinsic information preservation portion of image-reproducing means is the RGB color space of white point, redness, green, blueness.Therefore, identical with image data processed in this device, so respond well.But image-reproducing means is except being the device of processing RGB of representative with monitor and projecting apparatus, also has printer etc. to handle the device of CMYK.During this situation, make printer side have the predetermined RGB color space that comprises in the CMYK colour gamut of printer, as the reproduction color gamut information of printer.Thus, shared with the color gamut information way of realization of the device of other rgb spaces.And, have the RGB-CMYK converter section through making printer side, can the view data of RGB directly be outputed to printer side.Therefore, need not utilize image output device to carry out complex processing.Therefore,, also can show the image that effectively to apply flexibly the colour gamut of display unit, and not bear even can not change the low-grade output device of colour gamut.
(3) and, be not to carrying out treatment for correcting, but generate image, so have the advantage of color and the difficult generation of gray scale distortion according to colour gamut as the image that forms of the match colors of using the ICC private file.
(4) in addition, multiimage file has the main image data that writes down with the form according to the Exif specification according to the view data of sRGB (Standard RGB) specification and is auxiliary image data according to the view data of other specifications.
Through being the main image data of form of the Exif specification of establishing criteria specification to the Imagery Data Recording of the sRGB specification of establishing criteria; Even can not tackle the application program of multiimage file; Also can be read-only go into main image data; And because this main image data is the view data of the sRGB specification of standard, so which kind of application program no matter, view data to read in failed probability all lower.
Figure 15 is expression based on the figure of the structure of the video generation device of in the past match colors technology and image output device.
In the past, each image is generated image file, so video generation device generates a view data, image output device converts this view data to and is suitable for exporting behind the image-reproducing means.
Therefore, when the image quality of the view data that is generated by video generation device was the low image quality of the image quality that can reproduce than image-reproducing means, no matter how image output device was proofreaied and correct, and all can not export suitable image.
And image output device is conversion image data when each output, so the response shortcoming.This becomes significant disadvantages more when exporting to a plurality of image-reproducing means.
In this execution mode, constitute the image file that is stored as the image of corresponding a plurality of color gamut informations a file.As a result, the image of the image quality that is suitable for image-reproducing means can be provided all the time, and can offer image-reproducing means efficiently.
In addition, the video generation device 20 shown in this execution mode not only can be the difference independent structures with image output device 30, also can and integrate and use its function appropriate separation.
Figure 16 is the figure of the topology example of presentation video generating apparatus 20 and image output device 30.
And, also can be the device that constitutes by video generation device 20 and image output device 30 as new image output device or video generation device.
Figure 17 is the figure of other topology examples of presentation video generating apparatus 20 and image output device 30.
In addition, each function of explanation can use hardware to constitute in the above-described embodiment.And, also can make computer-readable go into to use software to record and narrate each functional programs and realize.And each function also can suitably select software, the arbitrary side of hardware to constitute.
In addition, each function also can realize through the program that computer is read in be stored in the not shown recording medium.At this, the recording medium of this execution mode can be any type of recording medium so long as computer-readable recording medium that can logging program gets final product.
Other advantages of the present invention for a person skilled in the art are obviously with distortion.So the present invention detail and the representative embodiments that illustrate and explain above aspect wider, being not limited in therefore.Thereby, can in aim that does not break away from the defined total invention category of appended claim of the present invention and equivalent thereof or scope, carry out various distortion to the present invention.
