Abstract
A blur checking region is determined by selecting a region in which a blur tends to clearly appear in a digital photograph image as the blur checking region. Then, an image of a region corresponding to the blur checking region is obtained as a checking image in a corrected image obtained by performing blur correction processing on the digital photograph image. Then, the obtained checking image is displayed in a size appropriate for the resolution of a display device.
Claims21
An image processing method comprising the steps of:
- determining a blur checking region by selecting a region in which a blur tends to clearly appear in a digital photograph image as the blur checking region, by:
- extracting edges from the digital photograph image;
- obtaining the number of the extracted edges for each of a plurality of regional images having the same size, which are formed by dividing the digital photograph image into blocks;
- and
- determining the blur checking region by selecting a region corresponding to a regional image which has a largest number of the edges as the blur checking region;
- obtaining an image of a region corresponding to the blur checking region as a checking image in a corrected image obtained by performing blur correction processing on the digital photograph image;
- and
- displaying the obtained checking image in a size appropriate for the resolution of a display device.
An image processing apparatus comprising:
- a blur checking region determination means for determining a blur checking region by selecting a region in which a blur tends to clearly appear in a digital photograph image as the blur checking region;
- a checking image obtainment means for obtaining an image of a region corresponding to the blur checking region as a checking image in a corrected image obtained by performing blur correction processing on the digital photograph image;
- and
- a display control means for displaying the obtained checking image in a size appropriate for the resolution of a display device,
- wherein the blur checking region determination means includes an edge extraction means for extracting edges from the digital photograph image, an edge number calculation means for obtaining the number of the extracted edges for each of a plurality of regional images having the same size, which are formed by dividing the digital photograph image into blocks, and a determination means for determining the blur checking region by selecting a region corresponding to a regional image which has a largest number of the edges as the blur checking region.
A computer readable memory in which a program for causing a computer to execute an image processing method is recorded, the program comprising the procedures for:
- blur checking region determination to determine a blur checking region by selecting a region in which a blur tends to clearly appear in a digital photograph image as the blur checking region;
- checking image obtainment to obtain an image of a region corresponding to the blur checking region as a checking image in a corrected image obtained by performing blur correction processing on the digital photograph image;
- and
- display control to display the obtained checking image in a size appropriate for the resolution of a display devices,
- wherein the procedure for blur checking region determination includes a procedure for extracting edges from the digital photograph image, a procedure for obtaining the number of the extracted edges for each of a plurality of regional images having the same size, which are formed by dividing the digital photograph image into blocks, and a procedure for determining the blur checking region by selecting a region corresponding to a regional image which has a largest number of the edges as the blur checking region.
