Abstract

An image processing apparatus that displays an image at a touch panel display, detects whether a face image is included in the displayed image, sets a point of the displayed image as a center point for a magnification ratio change based on the detected face image, and controls the touch panel display to change a magnification ratio of the displayed image centered at the center point based on a touch input received at the touch panel display.

Claims

1. (canceled)

2. :

An information processing apparatus comprising;

a touch panel display configured to display an image and to receive a touch input; and

circuitry configured to

control the touch panel display to display the image;

detect the touch input received by the touch panel display;

determine whether the touch input comprises a touch input for changing a magnification ratio of the image;

if the touch input comprises the touch input for changing the magnification ratio of the image, determine whether the touch input further comprises a drag input; and

if the touch input comprises both the touch input for changing the magnification ratio of the image and the drag input, change a magnification ratio of the image in accordance with the drag input and control the touch panel display to display the image with the changed magnification ratio.

3. :

The information processing apparatus of claim 2, wherein the circuitry is configured to

determine a distance of the drag operation; and

change the magnification ratio in accordance with the distance of the drag operation.

4. :

The information processing apparatus of claim 3, wherein the circuitry is configured to

change the magnification ratio concurrently with the drag operation while the drag operation is being performed; and

control the touch panel display to change the image with the changed magnification ratio concurrently with the drag operation while the drag operation is being performed.

5. :

The information processing apparatus of claim 2, wherein the circuitry is configured to

determine a direction of the drag operation;

increase the magnification ratio if the direction of the drag operation is a first direction; and

decrease the magnification ratio if the direction of the drag operation is a second direction that is different from the first direction.

6. :

The information processing apparatus of claim 5, wherein the first direction and the second direction are opposite directions.

7. :

The information processing apparatus of claim 6, wherein the opposite directions are an upward direction and a downward direction.

8. :

The information processing apparatus of claim 5, wherein the circuitry is configured to

determine whether the direction of the drag operation changes between the first direction and the second direction;

increase the magnification ratio if the direction of the drag operation changes from the second direction to the first direction; and

decrease the magnification ratio if the direction of the drag operation changes from the first direction to the second direction.

9. :

The information processing apparatus of claim 2, wherein the circuitry is configured to

determine whether the touch input comprises a pinch input; and

if the touch input comprises the pinch input, accept the pinch input as the touch input for changing the magnification ratio of the image and change the magnification ratio in accordance with the pinch input.

10. :

The information processing apparatus of claim 2, wherein the circuitry is configured to detect the touch input for changing the magnification ratio of the image and the drag input as separate operations performed on the touch panel display.

11. :

The information processing apparatus of claim 2, wherein;

the touch panel display has a center point; and

the circuitry is configured to set the center point of the touch panel display as a center point for changing the magnification ratio.

12. :

An image display method comprising;

displaying an image on a touch panel display;

receiving a touch input through the touch panel display;

determining, using circuitry, whether the touch input comprises a touch input for changing a magnification ratio of the image;

if the touch input comprises the touch input for changing the magnification ratio of the image, determining, using the circuitry, whether the touch input further comprises a drag input; and

if the touch input comprises both the touch input for changing the magnification ratio of the image and the drag input, changing, using the circuitry, a magnification ratio of the image in accordance with the drag input and controlling the touch panel display to display the image with the changed magnification ratio.

13. :

A non-transitory computer-readable medium including computer program instructions that, when executed by an information processing apparatus, cause the information processing apparatus to perform a method comprising;

displaying an image on a touch panel display;

receiving a touch input through the touch panel display;

determining whether the touch input comprises a touch input for changing a magnification ratio of the image;

if the touch input comprises the touch input for changing the magnification ratio of the image, determining whether the touch input further comprises a drag input; and

if the touch input comprises both the touch input for changing the magnification ratio of the image and the drag input, changing a magnification ratio of the image in accordance with the drag input and controlling the touch panel display to display the image with the changed magnification ratio
