Abstract

Disclosed is a method for correcting an image displayed by an electronic device including: obtaining a first region movable based on an input in a display region included in a display for displaying a first image, sensing that movement of the obtained first region has started based on the input, determining a characteristic of an image distortion correcting filter applied based on an orientation of the electronic device with respect to a ground based on the sensing, generating a second image by correcting the first image based on the movement based on the input and the determined characteristic of the image distortion correcting filter while the input is maintained, and displaying the generated second image on the display.

First claim

What is claimed is:

1. A method for correcting an image displayed by an electronic device, the method comprising:
obtaining a first region moveable by an input in a display region included in a display for displaying a first image;
sensing that movement of the obtained first region has started based on the input;
determining a characteristic of an image distortion correcting filter applied based on an orientation of the electronic device with respect to a ground based on the sensing;
while the input is maintained, generating a second image by correcting the first image based on the movement based on the input and the determined characteristic of the image distortion correcting filter and by filling a blank space defined in the display region while correcting the first image; and
displaying the generated second image on the display,
wherein a scheme for filling the space includes at least one of:
displaying an image of a periphery portion of the first image in the space,
repeatedly filling the first image in the space,
mirroring the first image and repeatedly filling the mirrored first image in the space,
filling the space with a color of the first image adjacent to the space, and
rendering an image having an area greater than the display region in advance by being expanded to have a width equal to or greater than a margin.

2. The method of claim 1 , further comprising:
setting a region to be scrolled based on the movement based on the input being performed in the first image as the first region.

3. The method of claim 1 , further comprising:
determining whether to apply the image distortion correcting filter based on whether the movement occurs at a speed equal to or less than a first speed, and a speed equal to or greater than a second speed, a minimum speed for viewing a jelly scroll phenomenon among speeds less than the first speed, or a threshold speed for viewing the jelly scroll phenomenon in the first region.

4. The method of claim 1 , further comprising:
applying the image distortion correcting filter based on the first image moving in a second direction perpendicular to a first direction, the first direction being a scanning direction of a scan line of the display.

5. The method of claim 1 , further comprising:
obtaining a correction value for correcting the first image based on a moving distance of the first image based on the input and/or a moving speed of the first image based on the input.

6. The method of claim 5 , wherein the correction value includes:
a first value, a coordinate value of each pixel of the first image in a first direction corresponding to a scanning direction of a scan line of the display; and
a second value, a coordinate value of each pixel of the first image in a second direction perpendicular to the first direction.

7. The method of claim 1 , wherein the scheme for filling the space includes:
displaying the image of the periphery portion of the first image in the space,
repeatedly filling the first image in the space,
mirroring the first image and repeatedly filling the mirrored first image in the space,
filling the space with the color of the first image adjacent to the space, and
rendering the image having the area greater than the display region in advance by being expanded to have the width equal to or greater than the margin.

8. An electronic device comprising:
at least one sensor;
a display configured to display an image in a display region;
at least one processor operatively connected with the at least one sensor and the display; and
a memory operatively connected to the at least one processor, wherein the memory stores instructions that, when executed, cause the processor to control the electronic device to:
obtain a first region moveable based on an input in the display region for displaying a first image;
sense that movement of the obtained first region has started based on the input;
determine a characteristic of an image distortion correcting filter applied based on an orientation of the electronic device with respect to a ground based on the sensing;
while the input is maintained, generate a second image by correcting the first image based on the movement based on the input and the determined characteristic of the image distortion correcting filter and by filling a blank space defined in the display region while correcting the first image; and

display the generated second image on the display,
wherein a scheme for filling the space includes at least one of:
displaying an image of a periphery portion of the first image in the space,
repeatedly filling the first image in the space,
mirroring the first image and repeatedly filling the mirrored first image in the space,
filling the space with a color of the first image adjacent to the space, and
rendering an image having an area greater than the display region in advance by being expanded to have a width equal to or greater than a margin.

9. The electronic device of claim 8 , wherein the instructions, when executed, cause the processor to control the electronic device to set a region to be scrolled based on the movement based on the input being performed in the first image as the first region.

10. The electronic device of claim 8 , wherein the instructions, when executed, cause the processor to control the electronic device to determine whether to apply the image distortion correcting filter based on whether the movement occurs at a speed equal to or less than a threshold speed in the first region.

11. The electronic device of claim 10 , wherein the instructions, when executed, cause the processor to control the electronic device to apply the image distortion correcting filter based on the first image moving in a second direction perpendicular to a first direction, the first direction being a scanning direction of a scan line of the display.

12. The electronic device of claim 8 , wherein the instructions, when executed, cause the processor to control the electronic device to obtain a correction value for correcting the first image based on a moving distance of the first image based on the input and/or a moving speed of the first image based on the input.

13. The electronic device of claim 12 , wherein the correction value includes:
a first value, a coordinate value of each pixel of the first image in a first direction corresponding to a scanning direction of a scan line of the display; and
a second value, a coordinate value of each pixel of the first image in a second direction perpendicular to the first direction.

14. The electronic device of claim 12 , wherein the scheme for filling the space includes:
displaying the image of the periphery portion of the first image in the space,
repeatedly filling the first image in the space,
mirroring the first image and repeatedly filling the mirrored first image in the space,
filling the space with the color of the first image adjacent to the space, and
rendering the image having the area greater than the display region in advance by being expanded to have the width equal to or greater than the margin.

15. A method for correcting an image displayed by an electronic device, the method comprising:
obtaining a first region moveable based on an input in a display region included in a display for displaying a first image;
sensing that movement of the obtained first region has started based on the input;
determining a characteristic of an image distortion correcting filter applied based on orientation of the electronic device with respect to a ground based on the sensing;
generate a second image by correcting the f
