Abstract

The image processing method and apparatus read photoelectrically an original image to obtain input image data and subject the input image data to image processing to obtain output image data. The method and apparatus perform first conversion for outputting an image file and second conversion for outputting a print as the image processing on the input image data obtained by a single image reading operation and output first image data for outputting the image file and second image data for outputting the print. The method and apparatus make it possible to output both of the photographic print and the image file, which have a good image quality, by a simple operation and with a high operation efficiency.

Claims

outputting first image data for outputting the image file and second image data for outputting the print.

2. The image processing method according to

claim 1

, wherein a resolution of said single image reading operation is set in accordance with output information of the print and the image file.

3. The image processing method according to

claim 1

, wherein said single image reading operation is performed with a resolution corresponding to one of sizes of the image file and the print to be output.

4. The image processing method according to

claim 3

, wherein said single image reading operation is performed with a resolution corresponding to a larger number of pixels required for outputting the image file or the print in accordance with the sizes of the image file and the print to be output.
