Display processing apparatus and display processing method

摘要

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.

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.
