Abstract
An image processing apparatus includes an identification unit configured to identify a contour region including a contour component in an input image, a determination unit configured to determine a scatter degree of the contour region in the input image, an emphasis processing unit configured to increase, in a case where the scatter degree of the contour region is greater than a determination value, an emphasis degree of the contour region in comparison to a case where the scatter degree is equal to or less than the determination value, and an output unit configured to output, to a display unit, the input image including the contour region in which the emphasis processing unit increases the emphasis degree.
Claims17
An image processing apparatus comprising:
- at least one processor;
- and
- at least one memory storing a program which, when executed by the at least one processor, causes the image processing apparatus to:
- identify a plurality of contour regions, each respectively including a contour component, in an image;
- determine a scatter degree of the plurality of contour regions in the image;
- increase, in a case where the scatter degree of the plurality of contour regions is greater than a first predetermined value, an emphasis degree of the plurality of contour regions in comparison to a case where the scatter degree is equal to or less than the first predetermined value;
- and
- output, to a display unit, the image including the plurality of contour regions, in which the emphasis degree of the plurality of contour regions is the increased emphasis degree,
- wherein the scatter degree is a degree to which the contour regions are spatially scattered in the image.
An image processing method using a processor to perform steps of:
- identifying a plurality of contour regions, each respectively including a contour component, in an image;
- determining a scatter degree of the plurality of contour regions in the image;
- increasing, in a case where the scatter degree of the plurality of contour regions is greater than a first predetermined value, the emphasis degree of the plurality of contour regions in comparison to a case where the scatter degree is equal to or less than the first predetermined value;
- and
- outputting, to a display unit, the image including the plurality of contour regions, in which the emphasis degree of the plurality of contour regions is the increased emphasis degree,
- wherein the scatter degree is a degree to which the contour regions are spatially scattered in the image.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute an image processing method comprising:
- identifying a plurality of contour regions, each respectively including a contour component, in an image;
- determining a scatter degree of the plurality of contour regions in the image;
- increasing, in a case where the scatter degree of the plurality of contour regions is greater than a first predetermined value, an emphasis degree of the plurality of contour regions in comparison to a case where the scatter degree is equal to or less than a first predetermined value;
- and
- outputting, to a display unit, the image including the plurality of contour regions, in which the emphasis degree of the plurality of contour regions is the increased emphasis degree,
- wherein the scatter degree is a degree to which the contour regions are spatially scattered in the image.
