Abstract

A display control device includes a display controller executing display control to display, on a display screen of a display device displaying an image, a whole of a display target image that is to be displayed and that has an aspect ratio differing from an aspect ratio of the display screen, and to display a partial enlarged image, which is obtained by enlarging a partial image corresponding to a part of the display target image and which has a smaller size than the display screen, at a displayed position of the partial image in superimposed relation to the display target image.

Claims

1. A display control device comprising:

a display controller executing display control to display, on a display screen of a display device displaying an image, a whole of a display target image that is to be displayed and that has an aspect ratio differing from an aspect ratio of the display screen, and to display a partial enlarged image, which is obtained by enlarging a partial image corresponding to a part of the display target image and which has a smaller size than the display screen, at a displayed position of the partial image in superimposed relation to the target image.

2. The display control device according to claim 1, further comprising a detector detecting an input externally applied to the display screen,

wherein when proximity to or a touch on the display screen is detected, the display controller displays the partial enlarged image obtained by enlarging the partial image that is displayed at a position corresponding to an instructed point on the display screen where the proximity or the touch has been detected.

3. The display control device according to claim 2, wherein when the proximity to the display screen is detected, the display controller displays the partial enlarged image, and

when the touch on the display screen is detected thereafter, the display controller starts scroll display of displaying an image after adjustment, which is obtained by adjusting a size of the display target image such that an end of the display target image in a direction defined by shorter one of horizontal and vertical sizes of the display target image is matched with a corresponding end of the display screen, while the image after the adjustment is scrolled in a direction corresponding to longer one of horizontal and vertical ends of the display screen, from a position in the image after the adjustment corresponding to a point where the touch has been detected.

4. The display control device according to claim 2, wherein when the touch on the display screen is detected, the display controller displays the partial enlarged image, and

when the touch on the display screen is released thereafter, the display controller starts scroll display of displaying an image after adjustment, which is obtained by adjusting a size of the display target image such that an end of the display target image in a direction defined by shorter one of horizontal and vertical sizes of the display target image is matched with a corresponding end of the display screen, while the image after the adjustment is scrolled in a direction corresponding to longer one of horizontal and vertical ends of the display screen, from a position in the image after the adjustment corresponding to a point where the touch has been released.

5. The display control device according to claim 2, wherein the display controller displays the display target image in such a size that an end of the display target image in a direction defined by longer one of the horizontal and vertical sizes of the display target image is matched with an end of the display screen.

6. The display control device according to claim 5, wherein on condition that a size of the display target image displayed on the display screen in a direction corresponding to shorter one of horizontal and vertical sizes of the display target image is denoted by H,

a size of the display screen in a lengthwise direction of the display target image is denoted by n,

a size of the display screen in a widthwise direction of the display target image is denoted by m,

in a two-dimensional coordinate system defined by an origin set at a lower left corner point of the display screen and two axes in a lengthwise direction and a widthwise direction of the display target image displayed on the display screen, a coordinate of the instructed point in the lengthwise direction is denoted by X, and

a positive value of which doubled value is smaller than n is denoted by a,

the display controller displays the partial enlarged image, which is obtained by enlarging a part of the display target image having lengthwise coordinates in a range of X-a×

H/m to X+a×

H/m to a size of 2a in the lengthwise direction×

m in the widthwise direction, over a lengthwise coordinate range of X−

a to X+a.

7. The display control device according to claim 6, wherein when the coordinate X of the instructed point in the lengthwise direction is larger than a and smaller than n−

a, the display controller displays the partial enlarged image, which is obtained by enlarging the part of the display target image having the lengthwise coordinates in the range of X−

a×

H/m to X+a×

H/m to the size of 2a in the lengthwise direction×

m in the widthwise direction, over the lengthwise coordinate range of X−

a to X+a,

when the coordinate X of the instructed point in the lengthwise direction is not larger than a, the display controller displays the partial enlarged image, which is obtained by enlarging the part of the display target image having the lengthwise coordinates in the range of X−

a×

H/m to X+a×

H/m to the size of 2a in the lengthwise direction×

m in the widthwise direction, over the lengthwise coordinate range of 0 to 2a, and

when the coordinate X of the instructed point in the lengthwise direction is not smaller than n−

a, the display controller displays the partial enlarged image, which is obtained by enlarging the part of the display target image having the lengthwise coordinates in the range of X−

a×

H/m to X+a×

H/m to the size of 2a in the lengthwise direction×

m in the widthwise direction, over the lengthwise coordinate range of n−

2a to n.

8. The display control device according to claim 7, wherein when the coordinate X of the instructed point in the lengthwise direction is not larger than a, the coordinate X is modified to a×

H/m when the coordinate X of the instructed point in the lengthwise direction is not larger than a×

H/m, and

when the coordinate X of the instructed point in the lengthwise direction is not smaller than n−

a, the coordinate X is modified to n−

a×

H/m when the coordinate X of the instructed point in the lengthwise direction is not smaller than n−

a×

H/m.

9. A display control method comprising:

executing display control to display, on a display screen of a display device displaying an image, a whole of a display target image that is to be displayed and that has an aspect ratio differing from an aspect ratio of the display screen, and to display a partial enlarged image, which is obtained by enlarging a partial image corresponding to a part of the display target image and which has a smaller size than the display screen, at a displayed position of the partial image in superimposed relation to the display target image.

10. A program causing a computer to function as display controller,

the display controller executing display control to display, on a display screen of a display device displaying an image, a whole of a display target image that is to be displayed and that has an aspect ratio differing from an aspect ratio of the display screen, and to display a partial enlarged image, which is obtained by enlarging a partial image corresponding to a part of the display target image and which has a smaller size than the display screen, at a displayed position of the partial image in superimposed relation to the display target image.
