Information retrieval apparatus and method |
摘要 |
An information retrieval apparatus includes a display section for displaying a first image; an enlargement section for continuously enlarging the first image displayed by the display section in response to an instruction of the user; and a determination section for determining that a magnification ratio of the first image enlarged by the enlargement section has reached a prescribed value. When the magnification ratio is determined to have reached the prescribed value, the display section displays at least one second image at a position related to the first image. When the first image is still enlarged by the enlargement section, the enlargement section enlarges the at least one second image at a magnification ratio equal to the magnification ratio used for enlarging the first image.
