Abstract
An image processing apparatus substantially performs image processing on an image including first gray-scale conversion processing using a first gray-scale conversion curve. Then, the image processing apparatus performs second gray-scale conversion processing on the processed image using a second gray-scale conversion curve, and displays a composite gray-scale conversion curve combining the first and second gray-scale conversion curves.
Claims19
An image processing apparatus comprising:
- image processing means for performing a process on an image, the process changing a size of a high frequency component and using (i) a first gray-scale conversion process based on a first gray-scale conversion curve and (ii) a slope of the first gray-scale conversion curve;
- gray-scale conversion means for performing a second gray-scale conversion process on the high-frequency component size-changed image using a second gray-scale conversion curve;
- and
- first curve display means for displaying a composite gray-scale conversion curve combining the first and second gray-scale conversion curves.
An image processing apparatus comprising:
- an image processing section that performs a process on an image, the process changing a size of a high frequency component an using (i) a first gray-scale conversion process based on a first gray-scale conversion curve and (ii) a slope of the first gray-scale conversion curve;
- a gray-scale conversion section that performs a second gray-scale conversion process on the high-frequency component size-changed image using a second gray-scale conversion curve;
- and
- a display section that displays a composite gray-scale conversion curve combining the first and second gray-scale conversion curves.
An image processing method comprising:
- an image processing step of performing a process on an image, the process changing a size of a high frequency component and using (i) a first gray-scale conversion process based on a first gray-scale conversion curve and (ii) a slope of the first gray-scale conversion curve;
- a gray-scale conversion step of performing a second gray-scale conversion process on the high-frequency component size-changed image using a second gray-scale conversion curve;
- and
- a display step of displaying a composite gray-scale conversion curve combining the first and second gray-scale conversion curves.
A computer-readable storage medium storing a program for processing an image, the program comprising codes for executing:
- an image processing step of performing a process on an image, the process changing a size of a high frequency component and using (i) a first gray-scale conversion process based on a first gray-scale conversion curve and (ii) a slope of the first gray-scale conversion curve;
- a gray-scale conversion step of performing second gray-scale conversion process on the high-frequency component size-changed image using a second gray-scale conversion curve;
- and
- a display step of displaying a composite gray-scale conversion curve combining the first and second gray-scale conversion curves.
