Image processing method and apparatus
First Claim
1. An image processing method, comprising the steps of:
- acquiring not only input image data from the image recorded optically with a taking lens but also an information about the taking lens used to record said image;
obtaining lens characteristics of said taking lens from the acquired lens information; and
performing image processing schemes on said input image data by using the obtained lens characteristics and a position information for said recorded image;
wherein said input image data is subjected to the image processing schemes in a first direction of said recorded image and a second direction crossing the first direction and wherein said imaae processing schemes are performed in said first and second directions independently of each other.

Abstract
The image processing method and apparatus acquire input image data from the image recorded optically with a taking lens, acquire the information about the lens used to record the image and perform image processing schemes on the input image data using the acquired lens information, provided that the type of the lens used is identified from the acquired lens information and the intensity of sharpness enhancement of the corresponding image is altered in accordance with the identified lens type. Using the obtained lens characteristics as well as the position information for the recorded image, the input image data is subjected to aberration correction for correcting the deterioration in image quality due to the lens characteristics.

15. An image processing apparatus which acquires input image data from the image recorded optically with a taking lens and performs specified image processing schemes on the input image data to produce output image data, comprising:
- acquisition means for acquiring an information about the taking lens used to record said image;
storage means for storing characteristics of said taking lens in accordance with the information about said taking lens; and
image processing means which performs the image processing schemes on said input image data in both a first direction of said recorded image and a second direction crossing the first direction, by using an information about pixel positions of the input image and the characteristics of the related taking lens as read from said storage means in accordance with the information about the taking lens acquired by said acquisition means, wherein said image processing means performs said image processing schemes in said first and second directions independently of each other. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
- acquisition means for acquiring an information about the taking lens used to record said image;
- 29. An image processing method, comprising the step of subjecting image data representing an image recorded on an image recording medium to image processing schemes in either a first direction or a second direction crossing said first direction or both directions, wherein if said image processing schemes are to be performed in both said first and second directions, contents of the image processing schemes in each of said first and second directions are altered.
-
31. An image processing apparatus comprising:
-
image processing means for performing unidirectional image processing schemes on image data that represents an image recorded on an image recording medium; and
control means for controlling said image processing means such that image processing schemes are performed on said image data in either a first direction or a second direction crossing said first direction or both directions, wherein if said control means controls said image processing means such that said image processing schemes are performed in both said first and second directions, said control means alters contents of said image processing schemes in each of said first and second directions.
-
- 32. The image processing apparatus according to claim 32, wherein said control means alters the contents of said image processing schemes by changing values of parameters in the image processing schemes in each of said first and second directions.
