Abstract

There is provided an image processing apparatus, an image processing method, and an image processing program realizing natural scroll display and high-speed scroll. The image processing apparatus includes: a detector detecting a scroll request; and a processor, when the detector detects a high-speed scroll request, employing a blurred picture created through a blurring process as a new picture required for a subsequent update of image displayed in a scroll region, thereby generating an image to be displayed.

Claims

1. An image processing apparatus comprising:

a detector detecting a scroll request; and

a processor, when the detector detects a high-speed scroll request, employing a blurred picture created through a blurring process as a new picture required for a subsequent update of image displayed in a scroll region, thereby generating an image to be displayed.

2. The image processing apparatus according to claim 1, wherein the blurred picture is a picture blurred along a scroll direction.

3. The image processing apparatus according to claim 1, wherein the processor, when the detector detects the high-speed scroll request, adjusts update speed of image displayed in the scroll region so that a first visual scroll speed is equal to or higher than a second visual scroll speed, the first visual scroll speed representing a scroll speed in a high-speed scroll display with use of a plurality of blurred pictures, the second visual scroll speed representing a scroll speed in a high-speed scroll display with use of non-blurred pictures.

4. The image processing apparatus according to claim 1, wherein the processor, when the detector detects a low-speed scroll request, employs a non-blurred picture as a new picture required for the subsequent update of image displayed in a scroll region, thereby generating the image to be displayed.

5. The image processing apparatus according to claim 4, wherein the blurred picture is created with use of a part of a still picture or a picture used in low-speed scroll mode.

6. The image processing apparatus according to claim 5, wherein the blurred picture is created with use of a part of a still picture or a picture used in low-speed scroll mode, which is displayed just before entering high-speed scroll mode.

7. The image processing apparatus according to claim 6, wherein the processor, when the detector detects the high-speed scroll request, creates the blurred picture thereafter.

8. The image processing apparatus according to claim 1, further comprising a storage unit storing the blurred picture,

wherein the processor, when the detector detects the high-speed scroll request, reads the blurred picture from the storage unit.

9. The image processing apparatus according to claim 1, wherein the processor displays an indicator in a region of the displayed image and changes size of the indicator in accordance with scroll speed.

10. The image processing apparatus according to claim 9, wherein the processor allows the indicator to expand or contract in a direction orthogonal to a scroll direction in accordance with the scroll speed, so that the indicator covers a part of the displayed image.

11. The image processing apparatus according to claim 10, wherein the processor performs expansion or contraction of the indicator through changing the gradation thereof.

12. The image processing apparatus according to claim 1, wherein the processor allows a speaker to output scroll sound while the displayed image is scrolled, and adjusts volume or tone of the scroll sound in accordance with scroll speed.

13. The image processing apparatus according to claim 1, wherein the processor displays the generated image to be displayed.

14. The image processing apparatus according to claim 13, further comprising a display panel for displaying the generated image to be displayed.

15. An image processing method comprising:

detecting a scroll request; and

employing, when a high-speed scroll request is detected, a blurred picture created through a blurring process as a new picture required for a subsequent update of image displayed in a scroll region, thereby generating an image to be displayed.

16. A storing medium on which an image processing program is stored, the program allowing a computer to perform procedures of:

detecting a scroll request; and

employing, when a high-speed scroll request is detected, a blurred picture created through a blurring process as a new picture required for a subsequent update of image displayed in a scroll region, thereby generating an image to be displayed.
