Image processing apparatus, image processing method, and program

An image processing method, comprising:

• generating, by a normal interpolated image generation unit, an image that is interpolated between a plurality of original images reproduced along time series, the image being a normal interpolated image, based on each of the plurality of original images;
• extracting, by a high-frequency area extraction unit, a high-frequency area having a spatial frequency higher than a predetermined value in each of the plurality of original images;
• generating, by a high-frequency area interpolated image generation unit, an image that is interpolated between the plurality of original images, the image being a high-frequency area interpolated image, based on a change in position of the high-frequency area along with an elapse of time on the time series and on each of the plurality of original images;
• and
• executing, by a combination unit, combining processing to combine the normal interpolated image and the high-frequency area interpolated image.

A program causing a computer to execute:

• generating, by a normal interpolated image generation unit, an image that is interpolated between a plurality of original images reproduced along time series, the image being a normal interpolated image, based on each of the plurality of original images;
• extracting, by a high-frequency area extraction unit, a high-frequency area having a spatial frequency higher than a predetermined value in each of the plurality of original images;
• generating, by a high-frequency area interpolated image generation unit, an image that is interpolated between the plurality of original images, the image being a high-frequency area interpolated image, based on a change in position of the high-frequency area along with an elapse of time on the time series and on each of the plurality of original images;
• and
• executing, by a combination unit, combining processing to combine the normal interpolated image and the high-frequency area interpolated image.
