Abstract

A region in a displayed image is scraped away in accordance with a trail of touch with a touch pen or the like and an object showing “shavings” corresponding to the scraped-away region is generated. A display position of each of particles generated in accordance with a user'"'"'s operation with the touch pen 27 or the like varies over time, in line with physical motion in accordance with actual gravity. Namely, a speed of each of the particles successively varies in accordance with prescribed acceleration (comparable to gravity) and the display position thereof is successively updated in accordance with the successively varying speed.

said moving-state display step includes

an object generation step of generating said object when the color attribute of said change target region is changed, and

an object display position change step of varying over time a display position of the object generated in said object generation step.

4. The storage medium storing an image processing program according to claim 1, wherein

said image processing program causes said computer to further execute an object erase step of erasing the object after the moving state of said object is displayed.

5. The storage medium storing an image processing program according to claim 1, wherein

said input portion repeatedly obtains the input coordinate, and

said moving-state display step includes

obtaining a quantity of variation of said input coordinate, and

starting movement of said object at a speed in accordance with said quantity of variation.

6. The storage medium storing an image processing program according to claim 1, wherein

said input portion repeatedly obtains the input coordinate, and

said moving-state display step includes

obtaining a direction of movement of said input coordinate, and

starting movement of said object in a direction in accordance with said direction of movement.

7. The storage medium storing an image processing program according to claim 1, wherein

said moving-state display step includes

a variation quantity obtaining step of obtaining a quantity of variation of said input coordinate,

a mode selection step of selecting any of first and second modes based on said quantity of variation, and

an initial value setting step of setting an initial value of a first speed component along a first direction and an initial value of a second speed component along a second direction different from said first direction,

said mode selection step includes

selecting the first mode when said quantity of variation is smaller than a prescribed threshold value, and

selecting the second mode when said quantity of variation is greater than said prescribed threshold value, and

said initial value setting step includes

setting the initial value of said first speed component to zero and randomly setting the initial value of said second speed component when said first mode is selected, and

setting the initial value of said first speed component based on a component of the moving speed along said first direction and a random value and setting the initial value of said second speed component based on a component of the moving speed along said second direction and a random value when said second mode is selected.

8. The storage medium storing an image processing program according to claim 1, wherein

said moving-state display step includes displaying, regarding a plurality of partial regions within said change target region, a moving state of objects each having a color attribute in accordance with a color attribute before change of the corresponding partial region.

9. The storage medium storing an image processing program according to claim 8, wherein

said moving-state display step includes starting movement of each object after randomly setting at least one of a speed and a direction for each said object.

10. The storage medium storing an image processing program according to claim 2, wherein

said moving-state display step includes displaying a moving state of said object in number in accordance with an area of said change target region.

11. The storage medium storing an image processing program according to claim 10, wherein

said moving-state display step includes newly displaying a moving state of said object in number in accordance with an area of a region of which change of a color attribute in said color attribute change step has newly been indicated.

12. The storage medium storing an image processing program according to claim 11, wherein

said color attribute change step includes

setting, as a substantial change target region, a region except for a region in said change target region of which color attribute has already been changed, and

changing a color attribute only of said substantial change target region, and

said moving-state display step includes displaying a moving state of said object in number in accordance with an area of said substantial change target region of which color attribute has been changed in said color attribute change step.

13. The storage medium storing an image processing program according to claim 1, wherein

said target image includes a plurality of pixels each having the color attribute,

said moving-state display step includes displaying a moving state of a plurality of objects corresponding to a plurality of pixels included in said change target region respectively, a color attribute of each object being in accordance with a color attribute of each pixel before change, and

said color attribute change step includes changing the color attribute of the change target region in said target image to a transparent color attribute.

14. The storage medium storing an image processing program according to claim 10, wherein

said moving-state display step includes lowering, when an area of a region of which change of a color attribute in said color attribute change step has newly been indicated is great, a ratio of the number of said objects of which moving state is to be newly displayed to the area of that region.

15. The storage medium storing an image processing program according to claim 1, wherein

said moving-state display step includes displaying, regarding only a target region in said change target region set in advance with respect to said target image, a moving state of an object having a color attribute in accordance with a color attribute of that target region before change.

16. The storage medium storing an image processing program according to claim 15, wherein

said target image includes a plurality of pixels each having the color attribute, and
