Image producing method and apparatus
First Claim
1. An image producing method for producing different output images from an input image having been obtained, comprising the steps of:
- obtaining said input image that has a region covering all of said different output images and has a resolution corresponding to one output image of said different output images whose resolution is highest;
subjecting said obtained input image to at least one color conversion process, or a first scaling in accordance with said one output image whose resolution is highest and said at least one color conversion process to produce an intermediate image; and
subjecting said intermediate image to at least one of cropping appropriate to each output image, a second scaling based on a difference in resolution between said intermediate image and each output image, and color conversion into a color space of each output image to thereby produce said different output images.

Abstract
The image producing method and apparatus obtain an input image that has a region covering all of the different output images and has a resolution corresponding to one output image of the different output images whose resolution is highest, subject the input image to at least one color conversion process, or a first scaling in accordance with the one output image whose resolution is highest and the at least one color conversion process to produce an intermediate image and subject the intermediate image to at least one of cropping appropriate to each output image, a second scaling based on a difference in resolution between the intermediate image and each output image, and color conversion into a color space of each output image to thereby produce the different output images.

10. An image producing apparatus, comprising:
-
a scanner for photoelectrically reading an image from an original; and
an image processor for processing said image read with said scanner to obtain different output images, wherein, when said different output images are produced, said scanner reads a region of said original covering all of said different output images in a resolution corresponding to one output image of said different output images whose resolution is highest, and wherein said image processor subjects said image read with said scanner to at least one color conversion process, or a first scaling in accordance with said one output image whose resolution is highest and said at least one color conversion process to produce an intermediate image, which is then subjected to at least one of cropping appropriate to an output region of each output image, a second scaling based on a difference in resolution between said intermediate image and each output image, and color conversion into a color space of each output image to thereby produce said different output images.
