Abstract

According to one embodiment, there is provided a display processing apparatus, including: a display unit configured to display an image, the display unit having a screen on which the image is displayed; an input module configured to receive a first manipulation and a second manipulation, the first manipulation being a trace manipulation performed on the screen to define a tracing locus on the image being displayed, the second manipulation being different from the first manipulation; and a display controller configured to control the display unit to enlargedly display the image in a given range, upon simultaneously receiving the first manipulation and the second manipulation through the input module, the given range being determined based on the tracing locus.

Claims

1. A display processing apparatus, comprising:

a display unit configured to display an image, the display unit having a screen on which the image is displayed;

an input device configured to receive at least one of a first manipulation or a second manipulation, the first manipulation being a loop trace manipulation performed in a first rotational direction on the screen for defining a first range of the image, the second manipulation being a loop trace manipulation performed in a second rotational direction on the screen for defining a second range of the image, each of the first range and the second range having the same aspect ratio with the screen, wherein the first rotational direction is different from second rotational direction; and

a processing unit configured to

control, upon receiving the first manipulation, the display unit to display an enlarged display of the first range of the image, and

control, upon receiving the second manipulation, the display unit to display a reduced display of the image with respect to the second range,

wherein a tracing locus of the first manipulation has a vertical length and a horizontal length which correspond to a vertical side and horizontal side of a circumscribed rectangular of the tracing locus, and

wherein, upon receiving the first manipulation, the processing unit compares the vertical length and the horizontal length of the tracing locus to select the vertical length of the tracing locus or the horizontal length of the tracing locus, and defines the first range to have a horizontal side that coincides with the horizontal length of the tracing locus, or to have a vertical side that coincides with the vertical length of the tracing locus.

2. The apparatus of claim 1,

wherein the processing unit selects a longer one of the vertical length or the horizontal length of the tracing locus, and defines the first range to have the vertical side or the horizontal side that corresponds to the longer one of the vertical length or the horizontal length of the tracing locus.

3. The apparatus of claim 1,

wherein the input device is further configured to receive a third manipulation, the third manipulation being different from the first manipulation and from the second manipulation, and

the processing unit to control the display unit to display the enlarged display of the first range of the image upon simultaneously receiving the first manipulation and the third manipulation, and to control the display unit to display the reduced display of the image with respect to the second range upon simultaneously receiving the second manipulation and the third manipulation.

4. The apparatus of claim 3,

wherein the third manipulation includes a touch manipulation on the screen of the display unit.

5. The apparatus of claim 3,

wherein the third manipulation includes a manipulation on a keyboard.

6. A display processing method, the method comprising:

displaying an image on a screen of a display unit;

receiving by an input device at least one of a first manipulation or a second manipulation, the first manipulation being a loop trace manipulation performed in a first rotational direction on the screen for defining a first range of the image, the second manipulation being a loop trace manipulation performed in a second rotational direction on the screen for defining a second range of the image, each of the first range and the second range having the same aspect ratio within the screen, wherein the first rotational direction is different from second rotational direction, wherein a tracing locus of the first manipulation has a vertical length and a horizontal length which correspond to a vertical side and horizontal side of a circumscribed rectangular of the tracing locus;

displaying by a processing unit an enlarged display of the first range of the image upon receiving the first manipulation, wherein displaying the enlarged display of the first range of the image includes, upon receiving the first manipulation;

comparing by the processing unit the vertical length and the horizontal length of the tracing locus to select the vertical length of the tracing locus or the horizontal length of the tracing locus, and

defining by the processing unit the first range to have a horizontal side that coincides with the horizontal length of the tracing locus, or to have a vertical side that coincides with the vertical length of the tracing locus,

displaying by the processing unit a reduced display of the image with respect to the second range upon receiving the second manipulation.
