Abstract

A recording medium storing an image processing program according to one aspect of the present invention is a non-transitory computer-readable medium storing an image processing program to make a computer execute image processing on an image group on one timeline, the image processing program making the computer execute deriving a difference value that is based on a difference between pixel values of images that are adjacent in time series in the image group, and displaying a time-series difference image showing a time-series change in the difference value.

Claims

1. A non-transitory computer-readable medium storing an image processing program to make a computer execute image processing on an image group on one timeline, the image processing program making the computer execute:

deriving a difference value that is based on a difference between pixel values of images that are adjacent in time series in the image group; and

displaying a time-series difference image showing a time-series change in the difference value.

2. The non-transitory computer-readable medium storing an image processing program according to claim 1,

wherein the image processing program further makes the computer execute:

displaying a timeline image corresponding to the timeline and in time series; and

displaying, when an input selecting an arbitrary position on the timeline image is received, an image on the timeline corresponding to the selected position, and

in the display of the time-series difference image, the time-series difference image is displayed so as to correspond to the timeline image and in time series.

3. The non-transitory computer-readable medium storing an image processing program according to claim 2,

wherein the image processing program further makes the computer execute receiving designation of a color from a user, and

a range over which images containing a pixel of the designated color exist on the timeline is shown on the timeline image.

4. The non-transitory computer-readable medium storing an image processing program according to claim 1,

wherein the difference value is derived based on a largest difference between the pixel values of corresponding positions in the adjacent images.

5. The non-transitory computer-readable medium storing an image processing program according to claim 1,

wherein the difference value is derived based on an average value obtained by deriving the differences between pixel values of corresponding positions in the adjacent images, and averaging the differences of all the positions.

6. The non-transitory computer-readable medium storing an image processing program according to claim 1,

wherein the difference value is selectable from at least one of a first difference value that is derived based on a largest difference between the pixel values of corresponding positions in the adjacent images, and a second difference value that is derived based on an average value obtained by deriving the difference between the pixel values of corresponding positions in the adjacent images and averaging the differences of all the positions, and

prior to displaying the time-series difference image, the image processing program further makes the computer execute receiving selection of one of the first difference value and the second difference value from a user.

7. The non-transitory computer-readable medium storing an image processing program according to claim 1,

wherein the time-series difference image is represented by a graph.

8. The non-transitory computer-readable medium storing an image processing program according to claim 1

wherein the image processing program further makes the computer execute receiving designation, from a user, of an area on which to perform the image processing in an image, and

the difference value in the area of the designated image is derived.

9. The non-transitory computer-readable medium storing an image processing program according to claim 1,

wherein if images included in the image group are provided by color images, the difference value is derived without focusing on a specific color.

10. The non-transitory computer-readable medium storing an image processing program according to claim 1,

wherein if images included in the image group are provided by color images, the difference value is derived by focusing on a specific color.

11. The non-transitory computer-readable medium storing an image processing program according to claim 1,

wherein if images included in the image group are provided by color images, the image processing program further makes the computer execute receiving selection, from a user, of a specific color to be focused on in order to derive the difference value, and

the difference value is derived by focusing on the selected specific color.

12. The non-transitory computer-readable medium storing an image processing program according to claim 1,

wherein if images included in the image group are provided by color images, the image processing program further makes the computer execute receiving selection, from a user, of whether to focus on a specific color in order to derive the difference value, and

if selection indicating not to focus on a specific color in order to derive the difference value is received, the difference value is derived without focusing on a specific color, and if selection indicating to focus on a specific color in order to derive the difference value is received, the difference value is derived by focusing on a specific color that is designated by the user in the received selection.

13. An image processing apparatus for performing image processing on an image group on one timeline, comprising:

an image processing unit to derive a difference value that is based on a difference between pixel values of images that are adjacent in time series in the image group, and generate a time-series difference image showing a time-series change in the difference value; and

a display unit to display the time-series difference image.
