Image browsing device, computer control method and information recording medium

A computer control method comprising:

• a viewpoint position moving step of moving a position of a viewpoint in a virtual space where a plurality of image objects are placed, according to a view point moving operation carried out by a user;
• a far-near value obtaining step of obtaining a far-near value indicating an extent of apartness between the position of the viewpoint and a position of the respective image object;
• a semi-transparency degree determination step of determining a semi-transparency degree of the respective image object, based on the respective far-near value obtained at the far-near value obtaining step;
• a space image production step of producing a space image showing a picture obtained by viewing the virtual space from the position of the viewpoint, according to the semi-transparency degree of the respective image object, determined at the semi-transparency degree determination step;
• and
• a space image display step of displaying the space image produced at the space image production step;
• and
• selecting one or more selection image objects from one or more selection target image objects,
• wherein the one or more selection image objects are selected by a user using a cursor,
• wherein the plurality of image objects include the one or more selection target image objects that are shown opaque and one or more non-selection target image objects that are shown semi-transparent and wherein the semi-transparency degrees of the one or more selection target image objects differ from the semi-transparency degrees of the one or more non-selection target image objects by at least a predetermined value,
• wherein said opaque image objects are selectable by said cursor and said semi-transparent image objects are not selectable by said cursor, and
• wherein the semi-transparency degree determiner determines the semi-transparency degree of the respective image object such that an image object having a far-near value smaller than a predetermined first value is shown transparent, an image object having a far-near value equal to or larger than the first value and smaller than a predetermined second value is shown opaque, and an image object having a far-near value equal to or larger than the second value is shown semi-transparent.

A non-transitory information storage medium storing a program for causing a computer to function as:

• viewpoint position moving means for moving a position of a viewpoint in a virtual space where a plurality of image objects are placed, according to a viewpoint moving operation carried out by a user;
• far-near value obtaining means for obtaining a far-near value indicating an extent of apartness between the position of the viewpoint and a position of the respective image object;
• semi-transparency degree determination means for determining a semi-transparency degree of the respective image object, based on the respective far-near value obtained by the far-near value obtaining means;
• space image production means for producing a space image showing a picture obtained by viewing the virtual space from the position of the viewpoint, according to the semi-transparency degree of the respective image object, determined by the semi-transparency degree determination means;
• space image display means for displaying the space image produced by the space image production means;
• and
• image selection means for selecting one or more selection image objects from one or more selection target image objects,
• wherein the one or more selection image objects are selected by a user using a cursor,
• wherein the plurality of image objects include the one or more selection target image objects that are shown opaque and one or more non-selection target image objects that are shown semi-transparent and wherein the semi-transparency degrees of the one or more selection target image objects differ from the semi-transparency degrees of the one or more non-selection target image objects by at least a predetermined value,
• wherein said opaque image objects are selectable by said cursor and said semi-transparent image objects are not selectable by said cursor, and
• wherein the semi-transparency degree determiner determines the semi-transparency degree of the respective image object such that an image object having a far-near value smaller than a predetermined first value is shown transparent, an image object having a far-near value equal to or larger than the first value and smaller than a predetermined second value is shown opaque, and an image object having a far-near value equal to or larger than the second value is shown semi-transparent.
