Abstract
An image processor which provides a color space conversion characteristic suitable for an image includes a transfer unit which transfers digital color image data representing a desired image input by an image input unit and having a color space depending on the image input unit, and extraction unit which extracts a color space conversion characteristic used to convert the color space depending on the image input unit into another color space. The transfer unit transfers the digital color image data having the color space depending on the image input unit and the color space conversion characteristic.
Claims20
An image processing uprights comprising:
- transfer means for transferring digital color image data representing a desired image input by image input means and having a color space depending on said image input means;
- and
- extraction means for extracting a color space conversion characteristic used to convert the color space depending on said image input means into another color space,
- wherein said transfer means transfers the digital color image data having the color space depending on said image input means and the color space conversion characteristic, and
- wherein said transfer means has asynchronous transfer means and isochronous transfer means.
An image processing apparatus comprising:
- storage means for storing a plurality of profiles corresponding to a plurality of image pickup conditions;
- input means for inputting an image pickup condition which is set when a desired image is obtained;
- selection means for selecting a profile suitable for the image pickup condition from the plurality of stored profiles;
- and
- transfer means for transferring image data representing the desired image in correspondence with the selected profile,
- wherein said transfer means has asynchronous transfer means and isochronous transfer means.
An image processing method in which digital color image data is transferred to a reception device having storage means for storing a plurality of profiles corresponding to image pickup conditions in correspondence with index information, comprising the steps of:
- transferring by transfer means the digital color image data representing a desired image picked up by image pickup means and having a color space depending on said image pickup means;
- selecting a color space conversion characteristic used to convert the color space depending on said image pickup means into another color space in response to the desired image;
- and
- transferring by said transfer means the digital color image data having the color space depending on said image pickup means and index information representing the selected color space conversion characteristic,
- wherein said transfer means has asynchronous transfer means and isochronous transfer means.
An image processing method comprising the steps of:
- storing a plurality of profiles corresponding to desired image pickup conditions;
- inputting an image pickup condition which is set when a desired image is obtained;
- selecting a profile suitable for the image pickup condition from the plurality of stored profiles;
- performing color matching processing for the desired image by using the selected profile;
- and
- transferring by a transfer means image data representing the desired image in correspondence with the selected profile,
- wherein said transfer means has asynchronous transfer means and isochronous transfer means.
A storage medium storing a computer readable program for controlling an image processing method in which digital color image data is transferred to a reception device having storage means for storing a plurality of profiles corresponding to image pickup conditions in correspondence with index information, the program comprising the steps of:
- transferring by transfer means the digital color image data representing a desired image picked up by image pickup means and having a color space depending on said image pickup means;
- selecting a color space conversion characteristic used to convert the color space depending on said image pickup means into another color space in response to the desired image;
- and
- transferring by said transfer means the digital color image data having the color space depending on said image pickup means and index information representing the selected color space conversion characteristic,
- wherein said transfer means has asynchronous transfer means and isochronous transfer means.
A storage medium storing a computer readable program for controlling an image processing method comprising the steps of:
- storing a plurality of profiles corresponding to desired image pickup conditions;
- inputting an image pickup condition which is set when a desired image is obtained;
- selecting a profile suitable for the image pickup condition from the plurality of stored profiles;
- performing color matching processing for the desired image by using the selected profile;
- and
- transferring by a transfer means image data representing the desired image in correspondence with the selected profile,
- wherein said transfer means has asynchronous transfer means and isochronous transfer means.
