Image storing-transferring method and apparatus
View Patent ↗Disclosed herein is a method of storing or transferring an image along with an image-processing parameter for processing the image. When storing or transferring a second image for storage or transfer which has a second resolution for storage or transfer differing from a reference resolution, a reference image-processing parameter set according to a reference resolution image having the reference resolution is corrected based on a difference between the reference resolution and the second resolution, so that it becomes a second parameter corresponding to the second image. The second parameter obtained by the correction is stored or transferred along with the second image.
1. A method of storing or transferring an image along with an image-processing parameter for processing said image, said method comprising, when storing or transferring a second image for storage or transfer which has a second resolution for storage or transfer differing from a reference resolution, the steps of: acquiring a second image-processing parameter that corresponds to said second image, by making reference to a table in which said second resolution is correlated with said second image-processing parameter; and storing or transferring said second image-processing parameter along with said second image, wherein said second image-processing parameter is calculated based on the reference resolution,
wherein processing said image comprises applying a frequency-enhancing process or dynamic range process to said image, and said processing is based on said image-processing parameter.
2. The method according to claim 1 , wherein the image is a radiation image of a human body.
3. The method according to claim 1 , wherein the second image-processing parameter is further calculated based on the second resolution and a reference image-processing parameter, wherein the reference image-processing parameter corresponds to the image.
4. The method according to claim 1 , wherein the calculating of the second image-processing parameter comprises calculating a transformation function corresponding to the second resolution, generating a transformed image signal using the transformation function, and manipulating the transformed image signal to correspond to a reference image signal corresponding to the reference resolution.
5. An apparatus for storing or transferring an image along with an image-processing parameter for processing said image, said apparatus comprising: storage means for storing a table in which a second resolution of a second image for storage or transfer differing from a reference resolution is correlated with a second image-processing parameter; parameter acquiring means for acquiring said second image-processing parameter by making reference to said table; and means for storing or transferring said acquired second image-processing parameter along with said second image, wherein said second image-processing parameter is calculated based on the reference resolution,
wherein processing said image comprises applying a frequency-enhancing process or dynamic range process to said image, and said processing is based on second image-processing parameter.
6. An apparatus for storing or transferring a reference image having a reference resolution, said apparatus comprising:
a storage unit which stores a table comprising a second resolution of a second image, wherein the second resolution differs from the reference resolution, and is correlated with a second image-processing parameter, and wherein the second image-processing parameter is calculated based on the reference resolution;
a parameter acquiring unit which acquires said second image-processing parameter by referring to said table; and
a storage/transfer unit which stores or transfers said acquired second image-processing parameter along with said second image,
wherein processing said image comprises applying a frequency-enhancing process or dynamic range process to said image, and said processing is based on second image-processing parameter.
7. The apparatus according to claim 6 , wherein the image is acquired by reading a radiation image of a human body.
8. The apparatus according to claim 6 , wherein the second image-processing parameter is further calculated based on the second resolution and a reference image-processing parameter, wherein the reference image-processing parameter corresponds to the reference image.
9. The apparatus according to claim 6 , wherein the calculating of the second image-processing parameter comprises calculating a transformation function corresponding to the second resolution, generating a transformed image signal using the transformation function, and manipulating the transformed image signal to correspond to a reference image signal corresponding to the reference resolution.
