Abstract
Abstract 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
126 words
An information retrieval apparatus, comprising: 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, wherein 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; and 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.
Claim 2
Dependent Claim
126 words
An information retrieval apparatus, comprising: 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, wherein 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; and 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.
Claim 3
Dependent Claim
47 words
An information retrieval apparatus according to claim 1, further comprising a selection section for selecting the first image, wherein the enlargement section increases the magnification ratio of the first image in proportion to a time period in which the first image is selected by the selection section.
Claim 4
Dependent Claim
66 words
An information retrieval apparatus according to claim 1, further comprising a reduction section for continuously reducing the at least one second image displayed by the display section in response to an instruction of the user, wherein when the magnification ratio of the at least one second image reduced by the reduction section reaches a prescribed value, the display section deletes the at least one second image.
Claim 5
Dependent Claim
57 words
An information retrieval apparatus according to claim 3, further comprising another selection section for selecting the at least one second image, wherein the reduction section decreases the magnification ratio of the at least one second image in proportion to a time period in which the at least one second image is selected by the another selection section.
Claim 6
Dependent Claim
16 words
An information retrieval apparatus according to claim 2, wherein the selection section is a touch panel.
Claim 7
Dependent Claim
16 words
An information retrieval apparatus according to claim 4, wherein the selection section is a touch panel.
Claim 8
Dependent Claim
113 words
An information retrieval method, comprising the steps of: displaying a first image; continuously enlarging the first image displayed in the step of displaying in response to an instruction of the user; determining that a magnification ratio of the first image enlarged in the step of enlarging has reached a prescribed value, and displaying at least one second image at a position related to the first image when the magnification ratio is determined to have reached the prescribed value, and then, when the first image is still enlarged by the enlargement section, enlarging the at least one second image at a magnification ratio equal to the magnification ratio used for enlarging the first image.
Claim 9
Dependent Claim
113 words
An information retrieval method, comprising the steps of: displaying a first image; continuously enlarging the first image displayed in the step of displaying in response to an instruction of the user; determining that a magnification ratio of the first image enlarged in the step of enlarging has reached a prescribed value, and displaying at least one second image at a position related to the first image when the magnification ratio is determined to have reached the prescribed value, and then, when the first image is still enlarged by the enlargement section, enlarging the at least one second image at a magnification ratio equal to the magnification ratio used for enlarging the first image.
Claim 10
Dependent Claim
52 words
An information retrieval method according to claim 7, further comprising the step of selecting the first image, wherein the step of enlarging includes the step of increasing the magnification ratio of the first image in proportion to a time period in which the first image is selected in the step of selecting.
Claim 11
Dependent Claim
60 words
An information retrieval method according to claim 7, further comprising the steps of: continuously reducing the at least one second image displayed in the step of displaying in response to an instruction of the user; and deleting the at least one second image when the magnification ratio of the second image reduced by the reduction section reaches a prescribed value.
Claim 12
Dependent Claim
61 words
An information retrieval method according to claim 9, further comprising the step of selecting the at least one second image, wherein the step of reducing includes the step of decreasing the magnification ratio of the at least one second image in proportion to a time period in which the at least one second image is selected in the step of selecting.
