Abstract

An information processing apparatus of the present application includes a drawing unit that draws a line on an image in a drawing area displayed in a fixed mode, which displays an image by fixing a position of the image; a judgment unit that judges whether a position of the line during drawing by the drawing unit is positioned on a boundary indicating the drawing area; a mode switching unit that switches from the fixed mode to a predetermined mode other than the fixed mode in a case in which the position during drawing is judged as being positioned on the boundary indicating the drawing area by the judgment unit; and a display control unit that executes control to display the image based on the mode switched by the mode switching unit.

Claims

1. An information processing apparatus, comprising:

a drawing unit that draws a line on an image in a drawing area displayed in a fixed mode, which displays an image by fixing a position of the image;

a judgment unit that judges whether a position of the line during drawing by the drawing unit is positioned on a boundary indicating the drawing area;

a mode switching unit that switches from the fixed mode to a predetermined mode other than the fixed mode in a case in which the position during drawing is judged as being positioned on the boundary indicating the drawing area by the judgment unit; and

a display control unit that executes control to display the image based on the mode switched by the mode switching unit.

2. The information processing apparatus according to claim 1,

wherein the predetermined mode switched by the mode switching unit is a scroll mode that displays the image by scrolling.

3. The information processing apparatus according to claim 2,

further comprising a touch operation detection unit that detects an operation of contacting or approaching an object as a touch operation,

wherein the mode switching unit switches to the fixed mode in a case in which a touch operation cannot be detected for a predetermined period of time by the touch operation detection unit in the scroll mode.

4. The information processing apparatus according to claim 3,

wherein the mode switching unit switches to the fixed mode in a case in which a position of the touch operation detected by the touch operation detection unit in the scroll mode does not change for a predetermined period of time.

5. The information processing apparatus according to claim 2,

further comprising a touch operation detection unit that detects an operation of contacting or approaching an object as a touch operation,

wherein the mode switching unit switches to the fixed mode when a plurality of touch operations is detected by the touch operation detection unit around the same time during the scroll mode.

6. The information processing apparatus according to claim 1,

wherein the mode switching unit switches to the fixed mode upon scrolling the image to an arbitrary area in the scroll mode.

7. The information processing apparatus according to claim 1,

wherein an area of the boundary indicating the drawing area is a circumferential area of a display unit displayed by the display control unit.

8. The information processing apparatus according to claim 3,

wherein the mode switching unit switches a mode in response to the number of two-finger operations that are continuously detected by the touch operation detection unit.

9. An information processing method executed by an information processing apparatus that controls display of an image, comprising:

drawing a line on an image in a drawing area displayed in a fixed mode, which displays an image by fixing a position of the image;

judging whether a position of the line during drawing by way of the drawing is positioned on a boundary indicating the drawing area;

switching from the fixed mode to a predetermined mode other than the fixed mode in a case in which the position during drawing is judged as being positioned on the boundary indicating the drawing area by way of the judging; and

executing control to display the image based on the mode switched by way of the mode switching.

10. A non-transitory storage medium encoded with a computer-readable program that enables a computer of an information processing apparatus that controls display of an image to execute functions as:

a drawing unit that draws a line on an image in a drawing area displayed in a fixed mode, which displays an image by fixing a position of the image;

a judgment unit that judges whether a position of the line during drawing by the drawing unit is positioned on a boundary indicating the drawing area;

a mode switching unit that switches from the fixed mode to a predetermined mode other than the fixed mode in a case in which the position during drawing is judged as being positioned on the boundary indicating the drawing area by the judgment unit; and

a display control unit that executes control to display the image based on the mode switched by the mode switching unit.
